&lt;p&gt;&lt;span style="font-size:150%;"&gt;&lt;strong&gt;Positioning in a global context&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Most often, Revit models have been correctly configured with the appropriate local grid coordinates X (eastings) and Y (northings) directions. However, to correctly position a Revit&amp;nbsp;model in a global context, the iTwin connector requires a global position, which cannot be obtained solely from the X and Y values.&lt;/p&gt;
&lt;p&gt;Without this information, the models will therefore be positioned at the default location set in Revit.&lt;img style="max-height:311px;max-width:778px;" alt=" " height="311" src="/resized-image/__size/1556x622/__key/communityserver-wikis-components-files/00-00-00-05-55/07.png" width="778" data-uw-rm-ima="un" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 1 - Revit model at default set location&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;To achieve a correct positioning, the model file must be updated with the correct latitude and longitude values. Unlike other design applications where a user can select a global coordinate system from a built-in library, Revit relies on the input of latitude and longitude values. In return, these settings can be used not only to create a correctly positioned iModel but also for Revit solar studies and analysis. Furthermore, when exporting to IFC files, global coordinates will be made available.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:443px;max-width:775px;" alt=" " height="443" src="/resized-image/__size/1550x886/__key/communityserver-wikis-components-files/00-00-00-05-55/08.png" width="775" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 2 - Correctly positioned Revit model&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;

&lt;/div&gt;
&lt;h1 id="mcetoc_1h6dtig5e0"&gt;&lt;span style="font-size:inherit;"&gt;Revit Coordinates&lt;/span&gt;&lt;/h1&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;To achieve a correctly geolocated Model, typically a model file needs:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Shared coordinates established&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Survey Point set to local coordinates (X and Y location)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Latitude and Longitude set&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="mcetoc_1h6dtngo81"&gt;&lt;span style="font-size:inherit;"&gt;Survey Point (SP)&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;To set specific coordinates for the SP:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Select the SP&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Unclip the SP&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-05-55/pastedimage1690449774341v1.png" /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 3 - Unclipped Survey Point&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;em&gt;Use the Specify Coordinates at Point tool to set the coordinates for the SP. This is usually a known point supplied by a qualified surveyor indicating the nearest survey mark.&lt;/em&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;em&gt;&lt;img style="max-height:312px;max-width:693px;" alt=" " height="312" src="/resized-image/__size/1386x624/__key/communityserver-wikis-components-files/00-00-00-05-55/10.png" width="693" /&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 4 - Specify coordinates at point tool&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Set the North/South (Y) and East/West (X) orientation, the elevation and finally the angle to true north&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;img style="max-height:331px;max-width:312px;" alt=" " height="331" src="/resized-image/__size/624x662/__key/communityserver-wikis-components-files/00-00-00-05-55/11.png" width="312" /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 5 -&amp;nbsp;&amp;nbsp;- Specify coordinates&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;This will update the SP with the coordinates specified.&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Clip the SP again to ensure it cannot be accidentally modified&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;img style="max-height:130px;max-width:462px;" alt=" " height="130" src="/resized-image/__size/924x260/__key/communityserver-wikis-components-files/00-00-00-05-55/12.png" width="462" /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;Image 6 - updated Survey Point with example UTM84 coordinates&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;h2 id="mcetoc_1h6dto0s72"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Project Base Point (PBP)&lt;/span&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;The PBP is often used as a project coordinate point indicating key features on-site or a building set-out point. Measurements can then be taken from that point (PBP).&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:294px;max-width:525px;" alt=" " height="294" src="/resized-image/__size/1050x588/__key/communityserver-wikis-components-files/00-00-00-05-55/40283.png" width="525" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 7 - Project Base Point&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;The PBP will always be relative to the SP. Moving the PBP while the SP is in its clipped state will have no effect on the SP itself. The PBP only plays a minor role when creating iModels.&lt;/span&gt;&lt;/p&gt;
&lt;h3 id="mcetoc_1h6dtosvm3"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Verify the location in a CAD application&lt;/span&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Export a site drawing to a DWG file with shared coordinates enabled&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-05-55/pastedimage1690460087286v1.png" /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;Image 8 -&amp;nbsp;Export settings - Units &amp;amp; Coordinates&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Attach the exported file as a reference in MicroStation or Civil3D (AutoCAD)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;Select and enable a suitable global coordinate system from the library&lt;/li&gt;
&lt;li&gt;Turn on the background map&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img style="max-height:522px;max-width:544px;" alt=" " height="522" src="/resized-image/__size/1088x1044/__key/communityserver-wikis-components-files/00-00-00-05-55/15.png" width="544" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 9 - DWG export with background map overlay&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;A MicroStation or C3D file with the correct GCS can be used to acquire the latitude and longitude relative to the SP.&lt;/p&gt;
&lt;p&gt;&amp;lt;&amp;lt;&lt;em&gt;Insert link to training session&amp;gt;&amp;gt;&lt;/em&gt;&lt;/p&gt;
&lt;h3 id="mcetoc_1h6dtq7d34"&gt;Setting latitude and longitude&lt;/h3&gt;
&lt;p&gt;The latitude and longitude must be set before the Revit model can be connected to an iModel.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:155px;max-width:551px;" alt=" " height="155" src="/resized-image/__size/1102x310/__key/communityserver-wikis-components-files/00-00-00-05-55/16.png" width="551" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;Image 9 -&amp;nbsp; Updated lat / long in Revit&amp;nbsp;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;This will shift the location from the Blue Hill Cemetry near Boston to Coffs Harbour, NSW.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;The location settings can be found and modified in Manage-&amp;gt; Location.&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Define the location by selecting Default City List and entering the lat / long coordinates&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;Click OK and open the menu again to verify the settings&lt;/li&gt;
&lt;li&gt;Check that the pin is pointing to the correct location&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;em&gt;&lt;span style="color:#000000;"&gt;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;img alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-05-55/17.png" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;&amp;nbsp;Image 10 - Location and Site settings&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;h3 id="mcetoc_1h6dtqe7d5"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Resulting iModel&lt;/span&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;The finished iModel will be positioned at the defined location, with the SP matching the latitude and longitude values.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;&lt;img style="max-height:368px;max-width:643px;" alt=" " height="368" src="/resized-image/__size/1286x736/__key/communityserver-wikis-components-files/00-00-00-05-55/18.png" width="643" /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;em&gt;&lt;span style="color:#000000;"&gt;&lt;span style="color:#969696;font-size:75%;"&gt;Image 11 - Coordinates measured in an iTwin app&lt;/span&gt;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;h2 id="mcetoc_1h6dtqls86"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Eyeballing Method&lt;/span&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Additionally, this method can be used in cases where there are no local grid (X and Y) coordinates available. The SP can remain at 0,0 (the default location) BUT the latitude and longitude must be set.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Here, the lat / long can be grabbed from Google Maps, using an approximate location where the model can be positioned.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;In Google Maps click at the point, where the SP should be located&lt;/li&gt;
&lt;li&gt;Right-click and copy the coordinate values&lt;/li&gt;
&lt;li&gt;Add the latitude and longitude values to the&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;em&gt;Location and Site&lt;/em&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;menu&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img style="max-height:114px;max-width:434px;" alt=" " height="114" src="/resized-image/__size/868x228/__key/communityserver-wikis-components-files/00-00-00-05-55/19.png" width="434" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 12 - Grabbing coordinates from Google Maps&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Please note that this approach is not accurate and should only be used in cases where it is impossible to acquire accurate location information. Additionally, please be aware that measuring coordinates in the iModel will not be possible.&lt;/p&gt;
&lt;h2 id="mcetoc_1h6dtseu27"&gt;Notes&lt;/h2&gt;
&lt;p&gt;Consider using the SP for everything related to a &amp;lsquo;global&amp;rsquo; positioning of a project. The SP can be set to the location of a known survey marker or an existing fixed infrastructure feature, such as a utility access hole cover. Something with a known location, easily verifiable on site.&lt;/p&gt;
&lt;p&gt;Use the PBP for everything &amp;lsquo;project&amp;rsquo; related, such as linking Revit files with each other or to continue &amp;lsquo;working in CAD&amp;rsquo;.&lt;/p&gt;
&lt;p&gt;Independently verify any survey information.&lt;/p&gt;
&lt;p&gt;&lt;em&gt;There are multiple Revit workflows available describing the setup and use of shared coordinate systems and location settings. To discuss all would go beyond the scope of this document, and further advice can be found on the Autodesk website.&lt;/em&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;

&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Select the SP&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Unclip the SP&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;em&gt;Use the Specify Coordinates at Point tool to set the coordinates for the SP. This is usually a known point supplied by a qualified surveyor indicating the nearest survey mark.&lt;/em&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;em&gt;&lt;img style="max-height:312px;max-width:693px;" alt=" " height="312" src="/resized-image/__size/1386x624/__key/communityserver-wikis-components-files/00-00-00-05-55/10.png" width="693" /&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Set the North/South (Y) and East/West (X) orientation, the elevation and finally the angle to true north&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;img style="max-height:331px;max-width:312px;" alt=" " height="331" src="/resized-image/__size/624x662/__key/communityserver-wikis-components-files/00-00-00-05-55/11.png" width="312" /&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;This will update the SP with the coordinates specified.&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Clip the SP again to ensure it cannot be accidentally modified&lt;/span&gt;&lt;/li&gt;

&lt;h2 id="mcetoc_1h6dto0s72"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Project Base Point (PBP)&lt;/span&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;The PBP is often used as a project coordinate point indicating key features on-site or a building set-out point. Measurements can then be taken from that point (PBP).&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:294px;max-width:525px;" alt=" " height="294" src="/resized-image/__size/1050x588/__key/communityserver-wikis-components-files/00-00-00-05-55/40283.png" width="525" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 7 - Project Base Point&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;The PBP will always be relative to the SP. Moving the PBP while the SP is in its clipped state will have no effect on the SP itself. The PBP only plays a minor role when creating iModels.&lt;/span&gt;&lt;/p&gt;
&lt;h3 id="mcetoc_1h6dtosvm3"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Verify the location in a CAD application&lt;/span&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Export a site drawing to a DWG file with shared coordinates enabled&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-05-55/pastedimage1690460087286v1.png" /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;Image 8 -&amp;nbsp;Export settings - Units &amp;amp; Coordinates&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Attach the exported file as a reference in MicroStation or Civil3D (AutoCAD)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;Select and enable a suitable global coordinate system from the library&lt;/li&gt;
&lt;li&gt;Turn on the background map&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img style="max-height:522px;max-width:544px;" alt=" " height="522" src="/resized-image/__size/1088x1044/__key/communityserver-wikis-components-files/00-00-00-05-55/15.png" width="544" /&gt;&lt;/p&gt;

&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;A MicroStation or C3D file with the correct GCS can be used to acquire the latitude and longitude relative to the SP.&lt;/p&gt;
&lt;p&gt;&amp;lt;&amp;lt;&lt;em&gt;Insert link to training session&amp;gt;&amp;gt;&lt;/em&gt;&lt;/p&gt;
&lt;h3 id="mcetoc_1h6dtq7d34"&gt;Setting latitude and longitude&lt;/h3&gt;
&lt;p&gt;The latitude and longitude must be set before the Revit model can be connected to an iModel.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:155px;max-width:551px;" alt=" " height="155" src="/resized-image/__size/1102x310/__key/communityserver-wikis-components-files/00-00-00-05-55/16.png" width="551" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;Image 9 -&amp;nbsp; Updated lat / long in Revit&amp;nbsp;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;This will shift the location from the Blue Hill Cemetry near Boston to Coffs Harbour, NSW.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;The location settings can be found and modified in Manage-&amp;gt; Location.&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Define the location by selecting Default City List and entering the lat / long coordinates&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;Click OK and open the menu again to verify the settings&lt;/li&gt;
&lt;li&gt;Check that the pin is pointing to the correct location&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;em&gt;&lt;span style="color:#000000;"&gt;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;img alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-05-55/17.png" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;&amp;nbsp;Image 10 - Location and Site settings&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;h3 id="mcetoc_1h6dtqe7d5"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Resulting iModel&lt;/span&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;The finished iModel will be positioned at the defined location, with the SP matching the latitude and longitude values.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;&lt;img style="max-height:368px;max-width:643px;" alt=" " height="368" src="/resized-image/__size/1286x736/__key/communityserver-wikis-components-files/00-00-00-05-55/18.png" width="643" /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;em&gt;&lt;span style="color:#000000;"&gt;&lt;span style="color:#969696;font-size:75%;"&gt;Image 11 - Coordinates measured in an iTwin app&lt;/span&gt;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;h2 id="mcetoc_1h6dtqls86"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Eyeballing Method&lt;/span&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Additionally, this method can be used in cases where there are no local grid (X and Y) coordinates available. The SP can remain at 0,0 (the default location) BUT the latitude and longitude must be set.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Here, the lat / long can be grabbed from Google Maps, using an approximate location where the model can be positioned.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;In Google Maps click at the point, where the SP should be located&lt;/li&gt;
&lt;li&gt;Right-click and copy the coordinate values&lt;/li&gt;
&lt;li&gt;Add the latitude and longitude values to the&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;em&gt;Location and Site&lt;/em&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;menu&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img style="max-height:114px;max-width:434px;" alt=" " height="114" src="/resized-image/__size/868x228/__key/communityserver-wikis-components-files/00-00-00-05-55/19.png" width="434" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 12 - Grabbing coordinates from Google Maps&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Please note that this approach is not accurate and should only be used in cases where it is impossible to acquire accurate location information. Additionally, please be aware that measuring coordinates in the iModel will not be possible.&lt;/p&gt;
&lt;h2 id="mcetoc_1h6dtseu27"&gt;Notes&lt;/h2&gt;
&lt;p&gt;Consider using the SP for everything related to a &amp;lsquo;global&amp;rsquo; positioning of a project. The SP can be set to the location of a known survey marker or an existing fixed infrastructure feature, such as a utility access hole cover. Something with a known location, easily verifiable on site.&lt;/p&gt;
&lt;p&gt;Use the PBP for everything &amp;lsquo;project&amp;rsquo; related, such as linking Revit files with each other or to continue &amp;lsquo;working in CAD&amp;rsquo;.&lt;/p&gt;
&lt;p&gt;Independently verify any survey information.&lt;/p&gt;
&lt;p&gt;&lt;em&gt;There are multiple Revit workflows available describing the setup and use of shared coordinate systems and location settings. To discuss all would go beyond the scope of this document, and further advice can be found on the Autodesk website.&lt;/em&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;

&lt;p&gt;&lt;span style="font-size:150%;"&gt;&lt;strong&gt;Positioning in a global context&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Most often, Revit models have been correctly configured with the appropriate local grid coordinates X (eastings) and Y (northings) directions. However, to correctly position a Revit&amp;nbsp;model in a global context, the iModel connector requires a global position, which cannot be obtained solely from the X and Y values.&lt;/p&gt;
&lt;p&gt;Without this information, the models will therefore be positioned at the default location set in Revit.&lt;img style="max-height:311px;max-width:778px;" alt=" " height="311" src="/resized-image/__size/1556x622/__key/communityserver-wikis-components-files/00-00-00-05-55/07.png" width="778" data-uw-rm-ima="un" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 1 - Revit model at default set location&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;To achieve a correct positioning, the model file must be updated with the correct latitude and longitude values. Unlike other design applications where a user can select a global coordinate system from a built-in library, Revit relies on the input of latitude and longitude values. In return, these settings can be used not only to create a correctly positioned iModel but also for Revit solar studies and analysis. Furthermore, when exporting to IFC files, global coordinates will be made available.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:443px;max-width:775px;" alt=" " height="443" src="/resized-image/__size/1550x886/__key/communityserver-wikis-components-files/00-00-00-05-55/08.png" width="775" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 2 - Correctly positioned Revit model&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span style="font-size:inherit;"&gt;To achieve a correctly geolocated Model, typically a model file needs:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Shared coordinates established&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;Survey Point set to local coordinates (X and Y location)&lt;/span&gt;&lt;/li&gt;

&lt;/ul&gt;

&lt;li&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Export a site drawing to a DWG file with shared coordinates enabled&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-05-55/pastedimage1690460087286v1.png" /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;Image 8 -&amp;nbsp;Export settings - Units &amp;amp; Coordinates&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Attach the exported file as a reference in MicroStation or Civil3D (AutoCAD)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;Select and enable a suitable global coordinate system from the library&lt;/li&gt;
&lt;li&gt;Turn on the background map&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img style="max-height:522px;max-width:544px;" alt=" " height="522" src="/resized-image/__size/1088x1044/__key/communityserver-wikis-components-files/00-00-00-05-55/15.png" width="544" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 9 - DWG export with background map overlay&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;A MicroStation or C3D file with the correct GCS can be used to acquire the latitude and longitude relative to the SP.&lt;/p&gt;
&lt;p&gt;&amp;lt;&amp;lt;&lt;em&gt;Insert link to training session&amp;gt;&amp;gt;&lt;/em&gt;&lt;/p&gt;
&lt;h3 id="mcetoc_1h6dtq7d34"&gt;Setting latitude and longitude&lt;/h3&gt;
&lt;p&gt;The latitude and longitude must be set before the Revit model can be connected to an iModel.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:155px;max-width:551px;" alt=" " height="155" src="/resized-image/__size/1102x310/__key/communityserver-wikis-components-files/00-00-00-05-55/16.png" width="551" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;Image 9 -&amp;nbsp; Updated lat / long in Revit&amp;nbsp;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;This will shift the location from the Blue Hill Cemetry near Boston to Coffs Harbour, NSW.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;The location settings can be found and modified in Manage-&amp;gt; Location.&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="color:#000000;font-size:inherit;"&gt;Define the location by selecting Default City List and entering the lat / long coordinates&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;Click OK and open the menu again to verify the settings&lt;/li&gt;
&lt;li&gt;Check that the pin is pointing to the correct location&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;em&gt;&lt;span style="color:#000000;"&gt;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;img alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-05-55/17.png" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;em&gt;&lt;span style="color:#969696;"&gt;&amp;nbsp;Image 10 - Location and Site settings&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;h3 id="mcetoc_1h6dtqe7d5"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Resulting iModel&lt;/span&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;The finished iModel will be positioned at the defined location, with the SP matching the latitude and longitude values.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;&lt;img style="max-height:368px;max-width:643px;" alt=" " height="368" src="/resized-image/__size/1286x736/__key/communityserver-wikis-components-files/00-00-00-05-55/18.png" width="643" /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;em&gt;&lt;span style="color:#000000;"&gt;&lt;span style="color:#969696;font-size:75%;"&gt;Image 11 - Coordinates measured in an iTwin app&lt;/span&gt;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;h2 id="mcetoc_1h6dtqls86"&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Eyeballing Method&lt;/span&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;span style="color:#000000;"&gt;Additionally, this method can be used in cases where there are no local grid (X and Y) coordinates available. The SP can remain at 0,0 (the default location) BUT the latitude and longitude must be set.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Here, the lat / long can be grabbed from Google Maps, using an approximate location where the model can be positioned.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;In Google Maps click at the point, where the SP should be located&lt;/li&gt;
&lt;li&gt;Right-click and copy the coordinate values&lt;/li&gt;
&lt;li&gt;Add the latitude and longitude values to the&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;em&gt;Location and Site&lt;/em&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;menu&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img style="max-height:114px;max-width:434px;" alt=" " height="114" src="/resized-image/__size/868x228/__key/communityserver-wikis-components-files/00-00-00-05-55/19.png" width="434" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="color:#969696;font-size:75%;"&gt;&lt;em&gt;Image 12 - Grabbing coordinates from Google Maps&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Please note that this approach is not accurate and should only be used in cases where it is impossible to acquire accurate location information. Additionally, please be aware that measuring coordinates in the iModel will not be possible.&lt;/p&gt;
&lt;h2 id="mcetoc_1h6dtseu27"&gt;Notes&lt;/h2&gt;
&lt;p&gt;Consider using the SP for everything related to a &amp;lsquo;global&amp;rsquo; positioning of a project. The SP can be set to the location of a known survey marker or an existing fixed infrastructure feature, such as a utility access hole cover. Something with a known location, easily verifiable on site.&lt;/p&gt;
&lt;p&gt;Use the PBP for everything &amp;lsquo;project&amp;rsquo; related, such as linking Revit files with each other or to continue &amp;lsquo;working in CAD&amp;rsquo;.&lt;/p&gt;
&lt;p&gt;Independently verify any survey information.&lt;/p&gt;
&lt;p&gt;&lt;em&gt;There are multiple Revit workflows available describing the setup and use of shared coordinate systems and location settings. To discuss all would go beyond the scope of this document, and further advice can be found on the Autodesk website.&lt;/em&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
