One recent addition SW2019 add the new sheet-tab under Material.
When we create custom material, the sheet-tab always appear.
The problem is when we want to apply that material to a body (PRT-weldment, so multi-body)
we get an error, and can't apply that material.
If we use the favorite, it work.
as we don't want-need "sheet-metal parameter" for that material, does anyone know how to disable it ?
that mean, return to normal material behaviour, like in 2018 and before.
others threads about it, but don't get my answer :
