Hi, I have this OBJ file from a smartphone app scan. Originally it was 50,000 triangles but I reduced it in Meshmixer to 13,488 triangles. it opens instantly in Meshmixer.

I need to convert it to 3DM for Alibre Design but when I try to import it into MoI3D V4 it takes a very long time on my fast PC.

Any ideas?

Thanks.
