      <description>&lt;P&gt;draw random points, use C3D and make TIN surface.&lt;/P&gt;</description>

      <description>&lt;P&gt;With a little LISP this should be possible (AutoCAD).&amp;nbsp;&lt;/P&gt;
&lt;P&gt;What I did (for testing):&amp;nbsp;&lt;/P&gt;
&lt;P&gt;- Create a number of random placed points (using a random number generator LISP)&lt;/P&gt;
&lt;P&gt;- draw lines between these points (triangulate LISP)&amp;nbsp; (see on the left side in the dwg)&lt;/P&gt;
&lt;P&gt;(- because the result of the&amp;nbsp; triangulate.lsp I used are 3DFaces I converted the faces into lines using the flatten command)&amp;nbsp;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;- put all the lines in a selection set&lt;/P&gt;
&lt;P&gt;- delete randomly selected lines from the selection set .&amp;nbsp; &amp;nbsp;=&amp;gt; the result on the right side&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I did not yet put this all in ONE LISP together, but I'm sure, if I repeat these steps I never will get the same result as shown in the attached example.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;You can refine this idea to your needs.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Randompoints get it here, from message number 7&lt;/P&gt;

&lt;P&gt;Triangulate code get it here, look for the one by CAB:&lt;/P&gt;

      <description>&lt;BLOCKQUOTE&gt;&lt;HR /&gt;&lt;a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/14233857"&gt;@a0985684202&lt;/a&gt;&amp;nbsp;wrote:&lt;BR /&gt;Could you please send your lisp code?&lt;BR /&gt;I &lt;U&gt;&lt;STRONG&gt;know nothing&lt;/STRONG&gt;&lt;/U&gt; about programming languages&lt;HR /&gt;&lt;/BLOCKQUOTE&gt;
&lt;P&gt;If that is true, the LISPs will be nearly worthless for you.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Nevertheless I post the 3 LISPs which I used in the attached zip.file.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Perhaps you can "play" with these, following this steps:&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;1.) load the mesh-test.lsp and run the command "test".&lt;/P&gt;
&lt;P&gt;=&amp;gt; a number of randomly placed points in a 1x1 area are created&lt;/P&gt;
&lt;P&gt;2.) load the triangulate-2.lsp and run the command "triangulate"&lt;/P&gt;
&lt;P&gt;=&amp;gt; after selecting all in step 1 created points a bunch of 3dfaces is created&lt;/P&gt;
&lt;P&gt;3.) run the command "flatten" (Express Tools) to convert the 3dfaces to lines.&lt;/P&gt;
&lt;P&gt;4.) run the command "overkill" (Express Tools) to delete duplicate lines.&lt;/P&gt;
&lt;P&gt;5.) load the del_lines.lsp&lt;/P&gt;
&lt;P&gt;=&amp;gt; after selecting all lines (from step 4) a number of randomly selected lines are deleted.&lt;/P&gt;
&lt;P&gt;6.) If necessary: Delete (manually) lines, which don't describe a closed area. (In the video were not such lines)&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;For demonstration a video:&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;div class="lia-vid-container video-embed-center"&gt;&lt;div id="lia-vid-6337220056112w996h540r535" class="lia-video-brightcove-player-container"&gt;&lt;video-js data-video-id="6337220056112" data-account="6057940548001" data-player="default" data-embed="default" class="vjs-fluid" controls="" data-application-id="" style="width: 100%; height: 100%;"&gt;&lt;/video-js&gt;&lt;/div&gt;&lt;script src="https://players.brightcove.net/6057940548001/default_default/index.min.js"&gt;&lt;/script&gt;&lt;a class="video-embed-link" href="https://forums.autodesk.com/t5/video/gallerypage/video-id/6337220056112"&gt;(ver en Mis vídeos)&lt;/a&gt;&lt;/div&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Again: This suggestion above is far away from a final solution. But perhaps it helps you to refine this idea to your needs.&lt;/P&gt;</description>
