Hello, I'm new to solidworks,

I like to know how to remove the part on a rounded surface after extrusion, like the case in the attached image.

Thank you

Hello

I must not be the only one, but I do not understand your problem.

I see that you have a dual-direction extrusion (a weak one below 0.Xmm and one in the 12.5mm above) on a case.

Thank you for your answer,

I found a solution that is simple, during the extrusion I chose "up to surface", so that the extrusion did not exceed the outer surface of the model.
