Hi,
well I know QuadRemesher and the VolumeBuilder, but this is
no option, if you have to deal with CAD-Files with hundreds of objects.
Also to clean them up, make them watertide, change co-planar faces etc. does not work
with such a mass of objects.
If there would be only one CAD-Object I could, of course, remodel or optimize it.
Maybe a special STP-import setting in C4D could help?
Because these are CAD Files from the client I cannot upload them.
But you can download some from Grabcad.com
Bad topology is the commonality of most CAD objects
Since C4D himself has major problems when it comes to boole complex CAD-Models
(artefacts/flickering/leavin entire object in render), my great hope was to solve this problem
with the Octane Clipping Mat.
regards
Mike
