Anonymous — Sat, 26 Sep 2020 16:10:12 GMT

In the first image, i tried to use the boolean difference to remash/solid in the two objects, in the second and the third image, i tried again to do the boolean difference and the hand simply dissapear. I want to do a cut in the finger equally in the new joint. Im new in this software.

thanks for the help.

Booleans fail often. Remeshing usually jiggles things around enough to fix it, unless there is non-manifold surfaces.

Please attach the .mix file (zipped). Also turn of the printer bed in the view, I can't see what you are trying to do.

Seems booleans are not failing in both cases (you get the blue/orange preview result)...

How does the second object you subtract or intersect looks like?

i made remesh/make solid (in the hand) / put an sphere to simulates a hole using boolean difference. The photo in purple is the place where i want to replica the same format in that place.

Anexed the .rar with the mix and the photo

Hmm, BooleanDifference does its job on your file without any issues:

Note: You need to have the palm activated as the first object. Then activate the sphere as the second object (A-B isn't equal to B-A)

But if you intend to put cables into cable tubes: There's a special tool in MM's EDIT toolset: AddTube

Anyhow: First thing is to remove the old tubes' surfaces: SELECT a ring around each of the outlets and discard . This breaks the connections. Now you can use EDIT/SeparateShells to separate the main surface and repair the open boundaries using ANALYSIS/Inspector...
