App crashes when carve two cylinders

[jetspydragon]

I just baught the application. When I try to carve a cylinder with another application crashes.

The attach is the map with de cylinder that I have selected when I choose Tools / Carve.

Hello, and welcome. I tried to reproduce your error, but my attempt worked correctly:

Is this a problem you can easily re-create? Can you upload a map file that will produce the error if I use the carve tool on one object? The forum allows ZIP file attachments.

I think that you are using a 16 size cylinder. I test it and yes, that works ok. The crash occurs with 32 size cylinder. The map now is a little differente but there are the two cylinders with the problems. It crash every time.

In the attachment is the map with the cylinders.

Perfect, thank you. I can produce the error on my end with this scene. This will get fixed pretty soon.

I think I should mark that as a ¿solution?... future solution perhaps. Thanks! In the meantime I'll keep exploring the software.

I will post another response when it is solved. This is my system for tracking bugs, so it's best to keep it unsolved until I am finished. Thanks for reporting this!

I was able to prevent the crash. This isn't perfect, because there are some gaps being created by the carve operation. However, thsi always happens with complex boolean operations, and it is much preferable to making the application crash.

This will be included in the next build that goes up on the beta branch.

That spiral shape could be the culprit. It doesn't make sense to me, and with so many vertices, the edges are going to overlap.

That's just the result of slicing objects to make multiple convex shapes. Brushes must be convex, so concave shapes are made out of multiple convex shapes.

Carving a 32-sided cylinder out of another one, at a 90 degree angle...this may be as good as it gets. Every other CSG program I've ever seen has simi;ar issues when the geometry gets complex. The crash is fixed on the beta branch, so I will call this finished for now.
