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

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