The boolean in the attached file seems to fail in grasshopper but not in rhino.
this was done in rhino.
I have noticed that the solid boolean operations in grasshopper behave in different ways from the ones in rhino.
here are the two breps, all show as closed yet the boolean outputs the tube without the slot removed.
In this case, I suspect it is because the outer surface of the union is a polysurface from the coplanar faces of the input breps OR that the outer tube face and the outer slot face are at some tangent angle that makes the operation fail.
I’ve noticed that doing solid boolean operations where faces become tangent to one another tend to behave in inconsistent ways. any insight would be greatly appreciated.
also, I’ve read over other discussions where changing the tolerance of the file is mentioned as a solution. is there a separate tolerance setting for grasshopper and rhino?
