3D-CAD Import: Meshquality
Posted: 11 Oct 2013, 19:13
Hello Cad-Soft,
I tested the new Import VCL and try to import several CAD-files (acis, step, iges).
My expierence:
1. really slow
2. complex step parts don't works
3. the greatest problem, respective my really problem:
The result of the meshes (tesselation) is fine for theorem: "finite elements computation" but not for design
In example tesselation a cylinder, make vertices all 30°(degree)
The expected result:
circumference : 2*12=24 vertices (triangle)
Top+bottom: 12+12=24 vertices (triangles)
In sum 48 vertices.
But not so in the importer, the amount of vertices depends also on the cylinder length .
The result: 10-100 times more vertices as a professional cad-system.
So it is unusable for mechanical purposes and slow down the visualisation.
I think it's a problem of cascade but have the engine not a alternative way for tesselation ?
Please let me know what else I should/can do to improve the meshes.
Regards
Andy
