Hi,
Any idea why I can not run properly MergeAllCoplanarFaces on the closed polysurface object in the attached 3DM file (Big file >20MB so I zipped it)?.
The origin of the file is an STL that was converted to closed polysurface.
Thanks

You have a polysurface with over 8000 faces. Rhino has to wade through those to find surfaces that are coplanar which takes time. As an added complication, Rhino sees this as an invalid polysurface with surface normal issues.
Given that very few of those faces are actually planar, you would be better off using _MergeCoplanarFace and manually selecting the faces you want to merge.
Incidentally, in the file you uploaded the polysurface is open, not closed.

You can also build the object using NURBS in Rhino in an hour or so, using the STL mesh for measurements, getting something like this:
By way of comparison, this only has 139 faces.
