I need some help!! The attached file was modeled in 3ds max. The volume is 0.283 cc , its dimension is 31.24 mm X 7.36 mm X 7.36 mm. The model is manifold, it has 103752 vertices and 34584 faces. What i need to do: I need to reduce the number of vertices. I've used both Blender (remove double vertex) and Meshlab (unify duplicated vertices) both process reduced the vertex number to 17294 and maintain the face number of 34584. I cannot save this change, I've tried saving as collada and exporting it to stl and the vertex count remained at 103752. Can anyone help me do the following: 1.reduce the number of vertices 2.duplicate the object until it is just below the Shapeways limit of vertex count or file size of 64 mb, whichever comes first. or suggest what i can do to solve this problem or why isn't the changes i made in blender or meshlab cant be saved. thanks alot.
