Hi Thomas,
If you share that example of a scalpel with Compound Surfaces that you
defined, I can try and show what can be done.
Best,

Can you give me an example of how I can change the mesh sizes in
practice? Where do I change that option?

Hi Thomas,
I would suggest to play with the size of the mesh cells. There are
several ways:

Hello,
In this picture the top is the original mesh of the scalpel.
In the bottom
I defined some compound surfaces. The mesh changed but the
problem is that
even in the one compound surface the mesh goes from point to
point and is
smaller in the areas where there used to be a smaller surface.
I would like
to be able to have a uniform mesh across surfaces. Does this
make the
problem clear? Thanks for your help.
