    <description>&lt;P&gt;Hi Nicolò,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Although this not possible in plain AutoCAD, you can try this way:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;1/ Use attached&amp;nbsp;put_points.lsp to create points on the vertices of the 3D polylines&lt;/P&gt;&lt;P&gt;2/ Use attached&amp;nbsp;TRIANGULATE__Elpanov.lsp to create&amp;nbsp;&lt;SPAN&gt;3DFaces from points, created in step #1&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;3/ Convert 3D faces into mesh as described &lt;A href="https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Converting-3D-faces-into-mesh.html" target="_blank" rel="noopener"&gt;&amp;gt;&amp;gt;&amp;gt;&amp;gt;HERE&amp;lt;&amp;lt;&amp;lt;&amp;lt;&lt;/A&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Good evening everyone,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I admit I have been looking for a solution for days, but I couldn't find anything so far - I hope some may have a solution for me on this, so thanks in advance!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I basically have the survey of an highway, composed by 3D polylines, and available as .dwg file.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot 2024-03-08 alle 20.33.18.png" style="width: 267px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1335109i0E14B1F1DEFF19DD/image-dimensions/267x187?v=v2" width="267" height="187" role="button" title="Screenshot 2024-03-08 alle 20.33.18.png" alt="Screenshot 2024-03-08 alle 20.33.18.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;What I am trying to do is to have a solid/mesh/model in 3D.&lt;/P&gt;&lt;P&gt;With qGIS I am able to extract punctual cross sections with the elevation profile, but I'd prefer to have the whole infrastructure in 3D to have a solid/mesh to reproduce the topography of the whole thing.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Do you know if there is a possible solution to do this?&lt;/P&gt;&lt;P&gt;I don't know if I explained well what I am trying to do, eventually just ask me for more info&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks again,&lt;/P&gt;&lt;P&gt;Have a nice evening&lt;/P&gt;&lt;P&gt;N&lt;/P&gt;</description>
