&lt;p&gt;&lt;strong&gt;Original Article Date:&lt;/strong&gt; &lt;em&gt;December 2006&lt;/em&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Updated:&lt;/strong&gt;&amp;nbsp; &lt;em&gt;February 2011&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;MicroStation&amp;#39;s Auxiliary Coordinate Systems (ACS) now includes a tool to align an ACS with a reference. This tool will allow you to set up, measure and draw using the units of a scaled reference. And..it&amp;#39;s easy! The contents of this tutorial is for MicroStation V8 XM Edition - SELECT Update #1 (08.09.03.48) or later and was compiled from discussions on Bentley&amp;#39;s &lt;a href="http://discussion.bentley.com"&gt;news groups&lt;/a&gt;.&lt;/p&gt;
&lt;div style="border-bottom:#cccccc 1pt solid;"&gt;&lt;/div&gt;
&lt;p&gt;Download &lt;a href="/askingapics/308.zip"&gt;308.dgn&lt;/a&gt;, open it with MicroStation V8 XM Edition SELECT Update #1 (08.09.03.48) or later and follow along to learn something new!&lt;br /&gt;&lt;br /&gt;Take a peek at the &lt;em&gt;Model&lt;/em&gt; dialog and note the existance of two models: &lt;br /&gt;&lt;br /&gt;&lt;em&gt;203Kv Tower&lt;/em&gt; - A simple line drawing of a transmission tower drawn at 1:1 and set up in meters.&lt;br /&gt;&lt;em&gt;Plot Layout&lt;/em&gt; - An &amp;quot;A&amp;quot; size sheet layout (8 1/2 x 11) with the design model attached as a reference at a scale of 1:250. This model is set up in inches to coincide with the imperial paper size.&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic1.jpg" border="0" alt=" " /&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;Before getting into the ACS tool, let&amp;#39;s first take a couple of height measurements.&lt;br /&gt;&lt;br /&gt;Navigate to the &lt;em&gt;203Kv Tower&lt;/em&gt; model and using &lt;em&gt;Measure Distance&lt;/em&gt; (D+1) - measure the height of the tower.&lt;br /&gt;Note that it measures nearly 37 meters.&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic2.jpg" border="0" alt=" " /&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;Go to the &lt;em&gt;Plot Layout&lt;/em&gt; model and measure the height of the same tower that&amp;#39;s attached as a reference at 1:250. You should get a resulting distance of about 5.8 inches which is correct for the model that the measurement is being taken in. Remember, this particular model is set up in inches and the paper size you see is an 8 1/2 x 11.&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic3.jpg" border="0" alt=" " /&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;To measure the tower in meters, which are the units it was drawn in, go to &lt;em&gt;Settings &amp;gt; Drawing Scale&lt;/em&gt; and set the Working Units to &lt;em&gt;Meters / Centimters&lt;/em&gt;. Re-measure the height of the scaled reference and notice that the distance now reads about 0.15 meters.&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic3A.jpg" border="0" alt=" " /&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;Still - it&amp;#39;s no where near the actual 37 meters since the measuring tools are measuring the distance between the datapoints in the active model. In other words, it&amp;#39;s not taking the scale of the reference into consideration. Let&amp;#39;s fix all that by using an Auxiliary Coordinate System based on the scale of the reference!&lt;br /&gt;&lt;br /&gt;To enable accurate measuring of scaled references, you&amp;#39;ll need access to the auxiliary coordinate tool set. These tools are available as a separate tool box via &lt;em&gt;Tools &amp;gt; Auxiliary Coordinates&lt;/em&gt; or can be accessed via the &lt;em&gt;Auxiliary Coordinates&lt;/em&gt; dialog which you can open from &lt;em&gt;Utilities &amp;gt; Auxiliary Coordinates&lt;/em&gt;, or by selecting the &lt;em&gt;Auxilary Coordinates&lt;/em&gt; button from the &lt;em&gt;Primary Tools&lt;/em&gt; tool box.&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic4.jpg" border="0" alt=" " /&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;To set up an ACS from the scaled reference, select &lt;em&gt;Define ACS (Aligned by Reference)&lt;/em&gt; and identify the reference with a datapoint. Look at the dialog and notice that the &lt;em&gt;Scale&lt;/em&gt; column is now now populated with the scale the selected reference.&amp;nbsp; Since you might want to keep this ACS in the file, select &lt;em&gt;Copy ACS&lt;/em&gt; and enter a name such as &lt;em&gt;Tower&lt;/em&gt;. This enables you to easily recognize this particular ASC in the event that others are created in the same file.&lt;br /&gt;&lt;br /&gt;Note:&amp;nbsp; An alternative approach is to simply select &lt;em&gt;Create a New ACS&lt;/em&gt;&amp;nbsp; and set the scale manually from the &amp;nbsp;available picklist in the &lt;em&gt;Scale&lt;/em&gt; column.&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic5.jpg" border="0" alt=" " /&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;The last thing to do is to verify that all of this is working as designed and, of course, the easiest way to do that is to measure the height of the tower in meters. &lt;br /&gt;&lt;br /&gt;From the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog, select &lt;em&gt;Meters / Centimeters&lt;/em&gt; for the units. Select &lt;em&gt;Tower&lt;/em&gt; as the ACS and notice that it automatically fills in the scale as being 1:250. Take your height measurement an notice that it&amp;#39;s now correct.&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic6.jpg" border="0" alt=" " /&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;A couple of finishing notes:&lt;br /&gt;&lt;br /&gt;It&amp;#39;s not necessary to create an ACS from a scaled reference. If you prefer, you can simply select the correct &amp;quot;scale&amp;quot; from the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog. Of course, this may leave a little room for error so use caution when making your selection.&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic7.jpg" border="0" alt=" " /&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;A huge benefit of using an ACS is that it&amp;#39;s stored with the file and is applied to all tools. This enables you to use the scale (and/or rotation) of a reference to measure as well as draw new geometry! &lt;br /&gt;&lt;br /&gt;Lastly, you can tidy up the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog to only show the information you really need.&lt;br /&gt;Park it in your status bar and you&amp;#39;re ready to go!&lt;/p&gt;
&lt;table style="width:100%;" border="0" cellpadding="6"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img align="left" src="/askIngaPics/308Pic8.gif" border="0" alt=" " /&gt;&lt;/td&gt;

&lt;p&gt;Before getting into the ACS tool, let&amp;#39;s first take a couple of height measurements.&lt;br /&gt;&lt;br /&gt;Navigate to the &lt;em&gt;203Kv Tower&lt;/em&gt; model and using &lt;em&gt;Measure Distance&lt;/em&gt; (D+1) - measure the height of the tower.&lt;br /&gt;Note that it measures nearly 37 meters. &lt;/p&gt;
&lt;table cellpadding="6" border="0" style="width:100%;"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic2.jpg" align="left" border="0" alt="" /&gt; &lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;Go to the &lt;em&gt;Plot Layout&lt;/em&gt; model and measure the height of the same tower that&amp;#39;s attached as a reference at 1:250. You should get a resulting distance of about 5.8 inches which is correct for the model that the measurement is being taken in. Remember, this particular model is set up in inches and the paper size you see is an 8 1/2 x 11. &lt;/p&gt;
&lt;table cellpadding="6" border="0" style="width:100%;"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic3.jpg" align="left" border="0" alt="" /&gt; &lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;To measure the tower in meters, which are the units it was drawn in, go to &lt;em&gt;Settings &amp;gt; Drawing Scale&lt;/em&gt; and set the Working Units to &lt;em&gt;Meters / Centimters&lt;/em&gt;. Re-measure the height of the scaled reference and notice that the distance now reads about 0.15 meters. &lt;/p&gt;
&lt;table cellpadding="6" border="0" style="width:100%;"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic3A.jpg" align="left" border="0" alt="" /&gt; &lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;Still - it&amp;#39;s no where near the actual 37 meters since the measuring tools are measuring the distance between the datapoints in the active model. In other words, it&amp;#39;s not taking the scale of the reference into consideration. Let&amp;#39;s fix all that by using an Auxiliary Coordinate System based on the scale of the reference!&lt;br /&gt;&lt;br /&gt;To enable accurate measuring of scaled references, you&amp;#39;ll need access to the auxiliary coordinate tool set. These tools are available as a separate tool box via &lt;em&gt;Tools &amp;gt; Auxiliary Coordinates&lt;/em&gt; or can be accessed via the &lt;em&gt;Auxiliary Coordinates&lt;/em&gt; dialog which you can open from &lt;em&gt;Utilities &amp;gt; Auxiliary Coordinates&lt;/em&gt;, or by selecting the &lt;em&gt;Auxilary Coordinates&lt;/em&gt; button from the &lt;em&gt;Primary Tools&lt;/em&gt; tool box. &lt;/p&gt;
&lt;table cellpadding="6" border="0" style="width:100%;"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic4.jpg" align="left" border="0" alt="" /&gt; &lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;To set up an ACS from the scaled reference, select &lt;em&gt;Define ACS (Aligned by Reference)&lt;/em&gt; and identify the reference with a datapoint. Look at the dialog and notice that the &lt;em&gt;Scale&lt;/em&gt; column is now now populated with the scale the selected reference. &lt;/p&gt;
&lt;table cellpadding="6" border="0" style="width:100%;"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic5.jpg" align="left" border="0" alt="" /&gt; &lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;Since you might want to keep this ACS in the file, select &lt;em&gt;Copy ACS&lt;/em&gt; and enter a name such as &lt;em&gt;Tower&lt;/em&gt;. This enables you to easily recognize this particular ASC in the event that others are created in the same file.&lt;br /&gt;&lt;br /&gt;The last thing to do is to verify that all of this is working as designed and, of course, the easiest way to do that is to measure the height of the tower in meters. &lt;br /&gt;&lt;br /&gt;From the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog, select &lt;em&gt;Meters / Centimeters&lt;/em&gt; for the units. Select &lt;em&gt;Tower&lt;/em&gt; as the ACS and notice that it automatically fills in the scale as being 1:250. Take your height measurement an notice that it&amp;#39;s now correct. &lt;/p&gt;
&lt;table cellpadding="6" border="0" style="width:100%;"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic6.jpg" align="left" border="0" alt="" /&gt; &lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;A couple of finishing notes:&lt;br /&gt;&lt;br /&gt;It&amp;#39;s not necessary to create an ACS from a scaled reference. If you prefer, you can simply select the correct &amp;quot;scale&amp;quot; from the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog. Of course, this may leave a little room for error so use caution when making your selection. &lt;/p&gt;
&lt;table cellpadding="6" border="0" style="width:100%;"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic7.jpg" align="left" border="0" alt="" /&gt; &lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;A huge benefit of using an ACS is that it&amp;#39;s stored with the file and is applied to all tools. This enables you to use the scale (and/or rotation) of a reference to measure as well as draw new geometry! &lt;br /&gt;&lt;br /&gt;Lastly, you can tidy up the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog to only show the information you really need.&lt;br /&gt;Park it in your status bar and you&amp;#39;re ready to go! &lt;/p&gt;
&lt;table cellpadding="6" border="0" style="width:100%;"&gt;

MicroStation's Auxiliary Coordinate Systems (ACS) now includes a tool to align an ACS with a reference. This tool will allow you to set up, measure and draw using the units of a scaled reference. And..it's easy! The contents of this tutorial is for MicroStation V8 XM Edition - SELECT Update #1 (08.09.03.48) or later and was compiled from discussions on Bentley's &lt;a href="http://discussion.bentley.com"&gt;news groups&lt;/a&gt;.

&lt;br /&gt;
Take a peek at the &lt;em&gt;Model&lt;/em&gt; dialog and note the existance of two models: &lt;br /&gt;
&lt;br /&gt;
&lt;em&gt;203Kv Tower&lt;/em&gt; - A simple line drawing of a transmission tower drawn at 1:1 and set up in meters.&lt;br /&gt;
&lt;em&gt;Plot Layout&lt;/em&gt; - An &amp;quot;A&amp;quot; size sheet layout (8 1/2 x 11) with the design model attached as a reference at a scale of 1:250. This model is set up in inches to coincide with the imperial paper size. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic1.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
Before getting into the ACS tool, let's first take a couple of height measurements.&lt;br /&gt;
&lt;br /&gt;
Navigate to the &lt;em&gt;203Kv Tower&lt;/em&gt; model and using &lt;em&gt;Measure Distance&lt;/em&gt; (D+1) - measure the height of the tower.&lt;br /&gt;
Note that it measures nearly 37 meters. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic2.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
Go to the &lt;em&gt;Plot Layout&lt;/em&gt; model and measure the height of the same tower that's attached as a reference at 1:250. You should get a resulting distance of about 5.8 inches which is correct for the model that the measurement is being taken in. Remember, this particular model is set up in inches and the paper size you see is an 8 1/2 x 11. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic3.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
To measure the tower in meters, which are the units it was drawn in, go to &lt;em&gt;Settings &amp;gt; Drawing Scale&lt;/em&gt; and set the Working Units to &lt;em&gt;Meters / Centimters&lt;/em&gt;. Re-measure the height of the scaled reference and notice that the distance now reads about 0.15 meters. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic3A.jpg" border="0" align="left" /&gt; &lt;/td&gt;

&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic4.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
To set up an ACS from the scaled reference, select &lt;em&gt;Define ACS (Aligned by Reference)&lt;/em&gt; and identify the reference with a datapoint. Look at the dialog and notice that the &lt;em&gt;Scale&lt;/em&gt; column is now now populated with the scale the selected reference. 
&lt;/p&gt;

From the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog, select &lt;em&gt;Meters / Centimeters&lt;/em&gt; for the units. Select &lt;em&gt;Tower&lt;/em&gt; as the ACS and notice that it automatically fills in the scale as being 1:250. Take your height measurement an notice that it's now correct. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic6.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
A couple of finishing notes:&lt;br /&gt;
&lt;br /&gt;
It's not necessary to create an ACS from a scaled reference. If you prefer, you can simply select the correct &amp;quot;scale&amp;quot; from the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog. Of course, this may leave a little room for error so use caution when making your selection. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic7.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
A huge benefit of using an ACS is that it's stored with the file and is applied to all tools. This enables you to use the scale (and/or rotation) of a reference to measure as well as draw new geometry! &lt;br /&gt;
&lt;br /&gt;
Lastly, you can tidy up the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog to only show the information you really need.&lt;br /&gt;
Park it in your status bar and you're ready to go! 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;

&lt;p&gt;
MicroStation's Auxiliary Coordinate Systems (ACS) now includes a tool to align an ACS with a reference. This tool will allow you to set up, measure and draw using the units of a scaled reference. And..it's easy! The contents of this tutorial is for MicroStation V8 XM Edition - SELECT Update #1 (08.09.03.48) or later and was compiled from discussions on Bentley's &lt;a href="http://discussion.bentley.com"&gt;news groups&lt;/a&gt;. 
&lt;/p&gt;
&lt;div style="border-bottom: #cccccc 1pt solid"&gt;
&lt;/div&gt;
&lt;p&gt;
Download &lt;a href="http://www.askinga.com/askingapics/308.zip"&gt;308.dgn&lt;/a&gt;, open it with MicroStation V8 XM Edition SELECT Update #1 (08.09.03.48) or later and follow along to learn something new!&lt;br /&gt;
&lt;br /&gt;
Take a peek at the &lt;em&gt;Model&lt;/em&gt; dialog and note the existance of two models: &lt;br /&gt;
&lt;br /&gt;
&lt;em&gt;203Kv Tower&lt;/em&gt; - A simple line drawing of a transmission tower drawn at 1:1 and set up in meters.&lt;br /&gt;
&lt;em&gt;Plot Layout&lt;/em&gt; - An &amp;quot;A&amp;quot; size sheet layout (8 1/2 x 11) with the design model attached as a reference at a scale of 1:250. This model is set up in inches to coincide with the imperial paper size. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic1.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
Before getting into the ACS tool, let's first take a couple of height measurements.&lt;br /&gt;
&lt;br /&gt;
Navigate to the &lt;em&gt;203Kv Tower&lt;/em&gt; model and using &lt;em&gt;Measure Distance&lt;/em&gt; (D+1) - measure the height of the tower.&lt;br /&gt;
Note that it measures nearly 37 meters. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic2.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
Go to the &lt;em&gt;Plot Layout&lt;/em&gt; model and measure the height of the same tower that's attached as a reference at 1:250. You should get a resulting distance of about 5.8 inches which is correct for the model that the measurement is being taken in. Remember, this particular model is set up in inches and the paper size you see is an 8 1/2 x 11. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic3.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
To measure the tower in meters, which are the units it was drawn in, go to &lt;em&gt;Settings &amp;gt; Drawing Scale&lt;/em&gt; and set the Working Units to &lt;em&gt;Meters / Centimters&lt;/em&gt;. Re-measure the height of the scaled reference and notice that the distance now reads about 0.15 meters. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic3A.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
Still - it's no where near the actual 37 meters since the measuring tools are measuring the distance between the datapoints in the active model. In other words, it's not taking the scale of the reference into consideration. Let's fix all that by using an Auxiliary Coordinate System based on the scale of the reference!&lt;br /&gt;
&lt;br /&gt;
To enable accurate measuring of scaled references, you'll need access to the auxiliary coordinate tool set. These tools are available as a separate tool box via &lt;em&gt;Tools &amp;gt; Auxiliary Coordinates&lt;/em&gt; or can be accessed via the &lt;em&gt;Auxiliary Coordinates&lt;/em&gt; dialog which you can open from &lt;em&gt;Utilities &amp;gt; Auxiliary Coordinates&lt;/em&gt;, or by selecting the &lt;em&gt;Auxilary Coordinates&lt;/em&gt; button from the &lt;em&gt;Primary Tools&lt;/em&gt; tool box. 
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic4.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
To set up an ACS from the scaled reference, select &lt;em&gt;Define ACS (Aligned by Reference)&lt;/em&gt; and identify the reference with a datapoint. Look at the dialog and notice that the &lt;em&gt;Scale&lt;/em&gt; column is now now populated with the scale the selected reference.
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic5.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
Since you might want to keep this ACS in the file, select &lt;em&gt;Copy ACS&lt;/em&gt; and enter a name such as &lt;em&gt;Tower&lt;/em&gt;. This enables you to easily recognize this particular ASC in the event that others are created in the same file.&lt;br /&gt;
&lt;br /&gt;
The last thing to do is to verify that all of this is working as designed and, of course, the easiest way to do that is to measure the height of the tower in meters. &lt;br /&gt;
&lt;br /&gt;
From the &lt;em&gt;Drawing Scale&lt;/em&gt; dialog, select &lt;em&gt;Meters / Centimeters&lt;/em&gt; for the units. Select &lt;em&gt;Tower&lt;/em&gt; as the ACS and notice that it automatically fills in the scale as being 1:250. Take your height measurement an notice that it's now correct.
&lt;/p&gt;
&lt;table border="0" cellpadding="6" width="100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td align="top" valign="top"&gt;&lt;img src="/askIngaPics/308Pic6.jpg" border="0" align="left" /&gt; &lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;
A couple of finishing notes:&lt;br /&gt;
&lt;br /&gt;
