Boolean union taking forever, hit esc.
Use MoveFace to pull out the inner Object face which is planar with the knob face,
do so both ends.
Boolean Union works.
then use MoveFace to put the face back to where it should be.
is this OK to do ?
I am making the sides vanish but do they ?
Is MoveFace a fix for Rhino’s failures with Boolean Union ?
Should I instead have not made the inner item overlap into the knob interior by .002inch to get a working boolean, or so I hoped !
but that would then also be co-planar or better described as co-surface (as it wasnt planar).
Is it only planar that is the problem ?
As it was, the interior wasnt the issue as I didnt opt for that, but I get the problem on those two rings, which in design were not to stick out.
Why cant boolean union do things that are designed to be ‘flush’ ?
I try V7 and it also fails. so Rhino just doesnt like unions of two items with a common face.
and trying to design to suit Rhino failing isnt easy or right.
So is this now ok or a time bomb, with a vanished 0.02 side surface shrunk back in at both ends of knob using MoveFace ?
Its a lot of fiddle to nuke it and move surfaces, shorten surfaces, trim and join etc. No doubt get naked dots etc.
