Hi all, In the Rhino WIP I’ve worked to add some quality of life improvements to the boolean commands (union, intersection, and difference). [Boolean Improvements | New in Rhino 9 WIP] These improvements include: Booleans will continue through failures This means if one part of mul…

And it’s kind of buggish because it uses the single .faces and not the packed one :man_shrugging:t2:

Should we show the ToNURBS options on the boolean commands if a SubD is selected?

It’s important having the chance to choose packed, yes.

I opened RH-88221 to get this fixed

Great stuff @Joshua_Kennedy ! I remember old Matrix 7.5 and 9 having a Boolean Builder Tool, with a few tricks to overcome some of the dificulties Rhino has with Booleans, especailly in the jewelry area, where sometimes you could have hundreds of cutters on several intersecting polysurfaces. More e…

There have been a lot of papers in the past few years in the area of mesh booleans (see Shaped Code ). Hopefully the team has been looking at these efforts as some of them are very impressive. I actually was able to try the Shaped Code implementation, and it was extremely fast and robust.

There is not enough information here. The orange surfaces do not fully intersect the grey surface. So at this point only 3 edges can be cut into the grey surface. What is the result that is asked for here? Is there any reason not to use a 4 sided surface to create the grey patch? [image] It i…

@Joshua_Kennedy Thank you for your ongoing improvements, especially in increasing the speed of this process compared to similar software. I hope that mesh boolean operations in Rhino will one day be as fast and robust as NURBS booleans, and on par with the performance seen in 3ds …

Hi @flexibility - @piac Did some revamping of the Mesh Booleans for Rhino 8 . Have you tried it? If there are cases you’re having issues with in Rhino 8, don’t hesitate to send them our way.
