Molding a part to a complex 3D geometry of another part

[Anonymous]

I can't seem to get my head around how to use the derive geometry feature.

I want to make a part that could hook over and slot into the original part (Body.ipt + first picture), that would look something like the example I made (HookPartExample.ipt + second picture), but I want them to sit flush against eachother with the same curvature since the original part is defined by a curvature like a bowl.

A clearer illustration of how I want the parts to fit together

I've done it the other direction. It's not really perfect, because the concave basic surface of the main part can't be recovered easily.

😐 Enough for today. It's late here ..

I assumed that this was for a soft silicone moulding over a hard plastic. Does this give you what you want?

Yes that’s perfect, thanks! Was that quite simple or complex to achieve?

I attached the model for you to reverse engineer.

I had to delete the holes to restore the curved face.

I then created a shape (new solid) the exact profile of the piece (cannot go over - hence filleted corners) so that I could extrude to Next.

The rest was just cosmetic. I had to go back and create a sketch of the holes (project geometry of face) before I deleted them. Then at the end I just extruded this sketch Through All.

Finally I made Solid 1 not visible to leave Solid 2.

Hi! I am not sure if this is what you were looking for. Please take a look at attached files.

Many thanks!

Does the attached video help?  I just derived the base in, then made a random extrusion, sculp cut the body out, and used delete face to clear and unwanted portion. Just a quick example.
