Since using RH7 i have been witnessing a unusual behavior when obtaining solid with entities mostly imported from other cads.
some of the solid obtained with booleans or by joining surfaces togheter are closed watertight polisrf but the some of the surfaces are inheriting colors from the source object. as a result i have a solid that behaves moslty normally but it does have some weird behavior when it comes to shading behavior + the waht commad is telling me its not a valid polisrf.
on the other side the _showedge command is not showing any issue with naked or nonmanifold edges.
I tried to explode polisrf, change color of all single surfaces and join them again but nothing change.
what does it depend on ? how can i erase all inherited properties and get a regular solid ?
