I use open drone map for processing drone imagery. It spits out a geo tif DEM but will also export a .obj file. If you can get your program to export an .obj or similar you should be able to bring that into FreeCAD.

Can't wait to try this out! Thanks!

Love this!

Thank everyone for all of your great work on all of this the icons are looking great to me.

Here are the icons in QGIS for reference.

I inquired on the Arch forum we'll see what they say. https://forum.freecadweb.org/viewtopic.php?f=23&t=59476

That is really exciting! I'm wondering if it might be a good idea to make sure that this work flow could use the building pads from what is used in Arch toolbox.

Blender has a new line art modifier that would do what you are describing. https://www.youtube.com/watch?v=vCxnbOCYELM
You could model it in FreeCAD and render the line art in blender.

Next step grade to surface from building pad? How would that work? I'm not a programmer or even an engineer but here is a process that I can imagine working. For areas that all cut or fill grading would be the same: Assign a desired cut and fill slope for polygon. Check if each vertex is above or be...
