How to change position of voxels in stl file?

Hello All,

Can I change the position of voxels connected with several triangles in stl file and maintaining the connectivity of my structure?

Many Thanks

Do you mean the vertices of the triangles? The answer, if you mean vertices, is yes, but this type of work is generally best accomplished in 3D modeling/editing programs (specifically either Blender or Meshlab), until the mesh manipulation capabilities are more developed within ImageJ.
