Hi everyone, I have two questions about the normal extrusion:
- As the base surface gets irregular errors are generated in the extrusion;
any way to smooth this behaviour?
- Is it possible to extrude a surface both directions? When I try (please
see the end of the .geo) this does not affect results.
It's still a bit experimental, but with recent builds you can use the
With Index" option. See attached file.
Thanks and kind regards,
Daniele
