I have a question about the 3D stl file processing.
Suppose that I have the 3D geometry (stl file).
I use stlread and trimesh command to plot it, then I found that some of elements are non-manifold.
I try to directly remove these two triangule faces for about entire afternoon, but I haven't done it succefully yet.
Could any one give me some suggestions?
Attached is the stl file, to view the stl file, with the codes as below:
