In some situations, it is not possible (or very very difficult) to modelize some "aesthetic" elements in CAD, and they need to be imported as 3D mesh.
An example is this robotic face cover modelled in Blender.
Those elements needs to interface with standard mechanical parts: structure, screws, ball-bearings, etc. in consequence, I had converted them to solid, allowing boolean operations between others (subtract operation visible in the picture above).
For converting a mesh to a solid in BricsCAD, I did:
1. Export the model as the standard 3D format
.dae making sure it is triangulated water-tight and has less than about 20K triangles.
2. Import it from BricsCAD
3. Select the model and
EXPLODE it, the result is a set of disconnected triangles
4. Select all the triangles (Ctrl+A) and convert all of them to regions:
REGION. The result is that each triangle now is a region. This only works with triangles, not with polygons.
5. Join all triangles into a solid: Select all regions (Ctrl+a) and
DMSTITCH. After a while, we get a body that can be edited into BricsCAD
The problem appear when I want to use a smoother model (more than approx. 20K triangles, which is still LOW-POLY), as in this case, DMSTITCH will refuse to work showing:
Too many entities selected
How to increase this limit?
The second problem is the huge amount of lines shown (white triangle edges in the top image): this make the screen over-crowded and it's difficult to work properly. Is there a way to avoid those lines to show? like telling the full body is a single curved face?
Thanks you and have a good day
