h.gagea> I have the problem on the face that becomes transparent but I can't fix it...
I think the problem comes from the Ø2mm holes (already existing on the step) which are tangent to the perpendicular surface... Well I don't know how to fix it...
make a cut to know if everything is in volume

We have to start from a stable import base.
Make a copy of the file, remove the functions, then redo the defective surface.
Once the volume is closed and clean, you save it under xt.
Then you open your current file , right click on your import, "edit function" and you go to get your xt file.
To finish you replay your functions on the new import.
Otherwise you can always try to do your piercing with a body tools.
Instead of a pocket you make an extrusion that you don't fuse with your main body (box unchecked in your "fused result" function), then you combine > subtract
Make a hole of 2mm +/- 1μm (if possible).
it will be "transparent" when drawing and it will solve the tangency problem
From memory, Topsolid handles zero thicknesses better than solidworks.
If you shift your tangent face by 1μ (or less depending on the accuracy of your dimensioning) you remove the tangiance and normally the zero thickness problem disappears
Not having managed to solve the problem, I tinkered with my 3D. I added material to have a solid again (and no longer have a transparent surface) and then I redesigned the holes at 1.999 (instead of 2mm).
Thank you all for your answers.
@ nathalie_1....; -)
your answer that you credit with best
is exactly my answer from 2 days ago
among other things, the addition of material
@+ ;-)
gt22> I didn't put a better answer because my solution is a mix of several answers that was postulated... Yours for the addition of material but also stefbeno for that of the smaller holes (because it was tangetic to the surface)
