hello,

I’m testing the boolean feature and am out of ideas on how I can get it to update/cut both items (or more) when I move an item. Don’t even know if this is possible.

Seems like the objects would need to be joined in order to make it work as is.

Anyone have any ideas?

For now, as it is, you can subtract only one mesh per step. Groups and lists are not supported. If you need two holes you’ll have to join those two meshes.

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

that’s what I thought. Do you know if there’s a way to add clipping planes in a way that can get the same effect?

Four clipping planes to cut a square hole? Have no idea

Good. CSG not needed )))

here’s a test I did. Still trying to figure out the coordinate system, but it can be done.

well, I got one working but when I add another clipping plane hole, they both go away. I’ve seen configurators do it, so I know it’s possible, but don’t know if that is some three.js wizard writing their own code or not, but I might have to move on from this idea.

Here is the latest test:

With booleans being new this is an interesting thread but I was wondering what the real-world problem is that you are trying to solve with booleans? Maybe its not a real-world problem and thats fine too. Just curious. I have not come up with a business need for booleans yet but I am interested to see what others are thinking.

that’s a dead end direction. As a workaround you may use cloning and geometriy batching to make several holes in one step. one important thing: to be merged objects should have the same material.

In general, it’s needed for creating holes in parametric models (windows/doors in garage-type configurators or holes for wires in table tops). And for now this new puzzle can’t provide the required functionality

I’m building a shed/garage configurator and want to hide the inside framing so I don’t have a stud going through the window.

Sometimes I’d need to hide the door and maybe even a couple windows. Which is why I’d need more than one boolean per mesh.

I’m going to use physics and hide anything touching. And add additional studs per item added.

I guess I could use the same material on the edges. Would that separate out the similar material and leave the transparent material?

I’m just curious at this point.

Geometry batching works as follows: all selected meshes with the same material are merged into one mesh (providing one render call). If you try to merge a window and a door having different materials you’ll fail.

Or just wait a little. Maybe they’ll fix the issue before the release.

got it figured out. Just a matter of cutting the first hole, then save that mesh to run the next loop of the item being cut and reassigning the material.
