Negative volume cut out

[akasus90]

Hello there!

Is your feature request related to a problem? Please describe. I'm not good at 3d editing meshes in specific apps, but I feel realy comfortable use Prusa Slicer for this) Negative volume is my favorite tool in it (MORE HOLES FOR GOD OF HOLES!)), but main problem is that I can save them only in project (3mf) and I like to share my remixes with stl format.

Describe the solution you'd like It will be nice if app-user could not only mark volumes not to print, but edit model it self this way/

Describe how it would work I suggest to add in RMB menu for NV option to cut out this volume in model, make a permanent hole in it))

Describe alternatives you've considered And You could add some tools for modeling, which make this app a slicer with build-in mobel editor!)

Additional context I hope You will consider my reqest. Have a nice day! And may the Force be with You!)

I have the same issue. When searching, I found this: https://github.com/prusa3d/PrusaSlicer/issues/7594

That says:

Subtraction of negative meshes during export was implemented in 2.6.0-alpha6. Closing.

However, it seems that it's either not actually implemented, or it's not functioning properly, or something else. It's not working for me either.

@mooklepticon @akasus90 Hello, yes, booleans operations to export STL/OBJ feature was implemented in the 2.6.0-alpha6, but the algorithm have a limitation: the algorithm may fail on non-manifold geometries (e.g., those containing self-intersection, etc). In that case, the user is notified, and only positive volumes are exported. So cannot be applied for all models/cases in this moments. Task created SPE-2480
