I am working on Freecad 0.17 for few days, to determine with the Arch workbench the volume of required backfill for a construction project, as explained in the documentation (https://www.freecadweb.org/wiki/Arch_Site).
I import the terrain as a mesh from a STL file, but its properties aren't calculated (area, perimeter).
Then the bakfill volume, at the moment represented as an simple extruded solid (the real surface will be more complex, but I try to work step by step ^^), can be "add" to the Site object, but this action doesn't have any visible effect.
The final goal of this work is to obtain the "addition volume" in the Site properties.
As Arch can't give any terrain properties, I guess there is a problem with my mesh, but I don't find what is it? The only point I see is the geometry complexity...
Some information on the study context: the project takes place in a flood zone. We have to implant the equipments (it's an industrial project) above a minimum level given by the authorities (6.7m here). So, a backfill volume has to be add to the terrain, but legislation requires than an equal volume has to be excavated on another part of the terrain. This is why I need to know this volume.
My workflow before Freecad:
Raw data are contour lines from a LIDAR survey (SHP file)
In QGIS, I extract the vertices of the lines, for my working zone, in a .SHP file
In BLENDER and its module Blender GIS, I create the mesh from these vertices (Delaunay triangulation) and I export the result in a .STL file
Backfill volume is created from a polyline imported in a DWF file, and simply extruded.
