Problem with partition

Hi everyone! I have created an stl file from a voronoi tesselation with 10 nodes. I have two problems with it.
The first one is that, as you can see when importing the geometry in comsol, most of the lines are curves when they should be straight. I guess that this a resolution issue, because when I plot it in Matlab is correct.
The second one, which is the really important, is with partition. I need to create a block 1x1x1 and delete everything which is outside of it. I've tried with partition objects but it doesn't work. Anybody knows something about this?
Regards, Alfonso

Hello Alfonso,
I played around with the settings in the mesh import part (under Mesh Part 1). I raised the relative tolerance to 0.001 and reduced the maximum face and edge neighbor angles by 20 deg each and now it works at least.
