Solid difference problem

Grasshopper
1

Hi
i have a cone and a box
operation1.0.gh (11.5 KB)
and i cant realize why this difference operation is not working.
thanks for any help how to correct that.

2

The results are solid, why do you think it fails?

3

the result are solid but there is no operation applied,
please see this attachment :
operation1.1.gh (11.1 KB)
both are solid but one has correct “boolean difference” result and next one has no boolean affect.

4

I don’t understand, both cubes are cut by the cone at my end.

well ,this is differ from my end, seems my Machine is breaking.do you mind if i ask your windows, rhino and grasshopper version? thanks

Maybe it is a problem of viewport display?

i baked the mesh and there was no difference, i will try at other machine to see if my windows “server” is causing this. thanks for help.

did you check units absolute tolerance in Rh ?

9

checked and increased accuracy,nothing changed also everything was fine with tolerance due to proper boolean on same box.

Try this send the surface as geometry debrep it list the face you want to call out and have it selected as list item then feeds it into isotrim them select the correct divide domain there’s two different divide domain gui’s and use the one that allows for two number inputs for uv direction or XY direction and you should be able to get the seems to match.

Fails because the computer doesn’t understand it.

I had the same problem.
I don’t know if it helps, but when I baked them and performed the boolean operation in Rhino it still didn’t work. Which means it must be a rhino thing not a Grasshopper thing.
I’ve noticed that this happens when the seam of one surface crosses a seam of the other surface. When I rotated the cone 180degrees, it was the other box that wasn’t cut. (so: an easy solution is rotate the cone 45 degrees)

there is no promise to boolean round shape always to do easy rotate
i think it would be better if dev team cover the seam issue in the code.
my problem solved by doing as much as possible diff boolean op all at once using entwine by another machine. and i think it solve the seam or something like “index”.

Cubicles normally work, then call out tris and extruder those.
