strange effect when revolve an half sphere (by greg)

I test solvespace by trying to dketch a sort of barrel of a revolver, but I can't do the round shape at the end of the grove.
File is in attachment, can't add a screenshot, but the half sphere is not totaly soustracted, and the inside of the solid appear . does anyone can explain? Is there a way to repair it?

Hi Greg,

this is probably related to the NURBS boolean operation. I forced the NURBS surfaces to Triangle Mesh in your file and it solved the problem. You can find this option in the Property Browser.

Click the group name in the property browser, and you will see at as the second tick box in the screen that comes up.

Just in case I added an image that shows the tick box (indicated with a red circle).

When I try to revolve this last function aroud the barrel, it doesn't works as expected, screenshot added, and no possibilities to force to triangle mesh as it is written as allready forced to triangle...

Any option?

Hi Greg,

the only way I got it working is by repeating your last sketch and lathe. It's not elegant at all because you have to repeat it five times but it works.

And the Solvespace file.

Thanks Eric,

Very not an elegant way to do, as if you have to change anything, you have to remember to do it for each instances.

But, ok, solvespace is not finnished and far for production way, is there any way to inform devellopment team for a bug found?

in attachement is a view of what I expected: all done with 5 fonctions. This way the design can be altered very easily.

I will check for update of the soft to test it regularely.

Hi Greg,

I think the best way to report a bug is through the github page of Solvespace. Go to and add a new issue. I found some guidelines here:
