V7/V8 - BUG - make2D fails on section view

Hi guys,
it seams that the ITALIAN Version 7 SR36 (7.36.23346.16351, 2023-12-12) fails in making the 2D drawing of a section view.

as you can see here when I do the Make2D commando the result is an empty solid also if the geometry is shown as closed solid.

Also the ITALIAN Version 8 SR6 (8.6.24086.11001, 2024-03-26)
does strange things. In the image the Make2D works as expected while the SectionDrawing fails like the V7.

The 3D model is an imported STEP file that I made it as closed PolySrf

Any suggestion?

@rajaa are you in charge of this?
or maybe @stevebaer ?

Here’s another ClippingPlane issue:
The printed drawing shows artifacts due to the overlapping cylinder.
The viewport doesn’t shows any issue.

To me it seams related to the previous problem.
This is V8 sr6

Thanks

@skysurfer can you share the model please? It helps to test with. Also, what options you chose when ran the ClippingDrawings command. Thanks
