Brep orientation

Hello, I want to extrude some breps along the direction of their faces. How can I choose the faces of the same orientation? It doesn’t work with “deconstruct brep > item list” because the orientation of the breps are not “correct”.

Can you share your file with us for better guidance?

Yes sure. So here you see my floor plates which I would like to extrude in x and y direction of 30 cm. So the thickness is ok. But I need them to be a bit bigger.

This could be a way to choose the same face normal directions of your breps. (1.3 MB)
