I have a mesh stored in ply file (or the obj equivalent). I'd like to do the following operation:
- If all the vertices are numbered (like v0,...vn) I'd like to specify a set indices to select those instead of selecting them manually.
- Once I select such vertices I'd like to remove all the other ones and keep those.
The idea would be to keep a small square region of the mesh (which essentially is an height map).
Is there a quick way to do such job?
I'm not a blender expert and sometimes the interface is a bit hard to understand.
I'm aware that If I press the B
button I can select using a box, but unless I align the camera correctly I always miss some of the points and include others that I don't actually need.
Any suggestion?
As example consider the following grid, and I'd like to crop it from 10x10 (original size) to, say, 4x4.
