&lt;p&gt;I am quite a beginner of OpenRail and I am using it it to test some workflows in producing alignments from shp/dgn files. I don&amp;#39;t even know if the workflows I am doing are intended or if I am forcing the program with bad workarounds.&lt;/p&gt;
&lt;p&gt;Input data: horizontal alignment as a Dgn or shp file extracted from QGIS.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;My goal is to get an alignment upon which I can put turnouts. My attempts have been:&lt;/p&gt;
&lt;p&gt;1)Get the geo-referenced shp as an attach ref --&amp;gt; merge into master --&amp;gt; Apply civil rule --&amp;gt; Create Complex. RESULT: no spirals or transition curves, the complex geometry is heavy as hell and slows down the pc. However, I can put turnouts on this.&lt;/p&gt;
&lt;p&gt;2) Create directly a complex geometry from the lines of the dgn/shp, without apply civil feature--&amp;gt; it turns out a more managble geometry which does not slow down the pc, but I can&amp;#39;t place turnouts because it says that it is a bspline.&lt;/p&gt;
&lt;p&gt;3) Get the shp/dgn file, then Create Regression Line --&amp;gt; Horizontal Regression --&amp;gt; The problem it creates weird&amp;nbsp;lines with no sense. I am attaching picture for reference...the zig-zag red line is the output of Horizontal regression.&lt;/p&gt;
&lt;p&gt;&lt;img src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/5921/pastedimage1664797850082v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;However, these three attempts are also far from what I desire, i.e. a good alignment with tangents, transition curves and spirals. From a course I have another alignment in .alg format, and when I apply civil rule to its elements they are correctly generated. The problem with these course is that datasets are always too nicely set up, and when you have other files from real situation they don&amp;#39;t work  &lt;/p&gt;
&lt;p&gt;I have very few time to perform other workflows or attempts...and from the forum, youtube videos and videos on bentley platform I cannot find nothing that can solve my problem.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Thank you for your help!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>Customization of json file for Rail imodel.</title><link>https://communities.bentley.com/products/digital-twin-cloud-services/itwin-services/f/itwin-services-forum/223798/customization-of-json-file-for-rail-imodel</link><pubDate>Wed, 22 Dec 2021 11:17:29 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:326822af-c971-4335-9ac2-ff8636dba882</guid><dc:creator>Mattia Mangia</dc:creator><description>&lt;p&gt;Hi to everybody. How can I customize the file with entities such as ballast, corridors etc like they do with the &amp;quot;ArchPhys&amp;quot; example in this link? &lt;a href="/products/digital-twin-cloud-services/itwin-services/w/synchronization-wiki/55909/modifying-default-mapping-for-ifc-exports"&gt;https://communities.bentley.com/products/digital-twin-cloud-services/itwin-services/w/synchronization-wiki/55909/modifying-default-mapping-for-ifc-exports&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I&amp;#39;m testing several IFC export procedures for a sample rail model and I found out that the IFC export created from the Connect portal or iTwin generates only meshes with a field &amp;quot;Description&amp;quot; in which is reported &amp;quot;Generic.PhysicalObject&amp;quot;.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Is there a way to exploit the schemamapping.json file like they do for architectural elements such as Doors and Windows? Thanks in advance for any answer.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>Ask A Question I</title><link>https://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09</link><pubDate>Wed, 22 Dec 2021 05:26:57 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:96c37bda-f30d-4959-b6b5-f1bccbd56cd3</guid><dc:creator /><description>Ask a question in a forum.</description></item></channel></rss>
