Hello everyone.

I'm doing a plugin and I have problems with BaseShellExtrude with transformation skecth.

The fact is that I have calculated a transformation matrix to extrude a sketch, when I apply the BaseShellExtrude Command the geometry is generated in both side of the sketch plane. I don't know why?
I took the transform matrix from CAE and it's exactly the same than mine, and if I use ShellExtrude command the geometry is generated correctly. The question is that I want to avoid using ShellExtrude due to I need to positionate a lot of parts and with ShellExtrude I should create a lot of reference geometry, such planes, Axis, ...
Anyone can help me? is there a convection for axis? due to, in general, the BaseShellExtrude works fine in my macro, but in specific points not.

Thank you in advance
