Civil Corner / Re: Problem: Surface boundary
« Last post by Lars on December 07, 2025, 09:40:35 AM »To create a boundary you need to include your boundary 3DPolyline in the triangulation as a breakline. Therefore yo need to check the box "Polyline (Vertex)" and select layer that contains the 3Dpolyline. Select all your items for the triangulation (boundary 3Dpolyline included) and triangulate.
You now will end up with a bunch of triangles probably inside and outside the boundary line. However if you plot your triangles to a new layer in the drawing (using Edit/View Triangles) and then copy your boundary line into that drawing you will see that triangles interfering your boundary line are cut at the location of the line.
Now you can use a tool in "Edit/View Surface" to delete triangles that are outside or inside a 3DPolyline (your boundary). If you have multiple boundaries you can do the same, include them in the triangulation as breaklines and the delete unwanted triangles manually. Finally you save all your remaining triangles as a surface using "Surface/Save Surface..". CadTools will recognize valid surface triangles while saving triangles from drawing to file, all other items will be excluded.

Civil Corner / Problem: Surface boundary
« Last post by ME-GEO on December 06, 2025, 11:43:00 AM »Why can't I select a boundary polygon when creating a surface? (See image.)
Or is it possible to clip the surface at a boundary polygon afterward?

CadTools Tips and Tricks / Re: AutoCAD 2025
« Last post by Lars on September 01, 2025, 09:28:56 AM »You need to have installed your CAD to get it in the list. CadTools scan the registry for supported CAD versions as it starts (in facts as it opens the "Settings" dialog).

If it is Slope and Road signs you are referring to you should change "Angle/Direction" (a) to 27

How can i draw chevrons with angle different than 45, i want the angle to be 27 (slope 2:1)
thank you.
