RE: Bug or TOUGH CASE with Booleans ... - ggaliens - 02-03-2019
If you watch the video, you can see exactly how I made it. I bet you GESTALT vision can also just SENSE / see when the smooth has been pressed enough time.
I just smoothed the knot and the geodome a couple times each. Just have my video up next to you wings screen and press smooth until there looks to be a resolution match.
I just tried with each smooth 3 times.
It failed.
Now I will try easier ... just smooth each TWICE. Still a fail With a message about coplanar faces. Wings 2.2.2
I try to take the coplanar faces warning for what it really says ... so I then do a crumple 1% to probably ensure zero or almost zero coplanar faces. Then it works.
What is the easiest way for me to share a file with you these days ?
Here is a share. Try to subtract knot from geodome

Yeah, if the objects are in default size and location, sure I could to try reproduce it. It was just hard to notice that using a smartphone.
You may know that's not easy to debug objects with this amount of faces. I crash Wings3D many times until get something with the minimum amount of faces that still can cause the crash and then send to dgud. That was the reason I thought to use the original would be better.
Google drive is ok for sharing files. Thanks.

If you cleanup (body/Cleanup) the "support" object, boolean works fine.
You have 3 pairs of vertexes in exactly the same place which causes problems
in the calculations.
I don't know how to solve problems with "bad" models in the code either.
A crash is not a good user message it gives no clue about what is bad, on the
other hand I don't want to write lots of code to figure out what is wrong with
the input either.
EDIT: Ok I solved the problem for this model, since the problematic area was not involved in the
boolean operation the problem could be fixed, but if you tried a boolean op on the bottom face it
will continue to crash.

Open the attachment and try to subtract any of the objects named "triangle" from the object named "support". Guaranteed failure, and very simple mesh. This is using 2.2.2 on Ubuntu Linux.
I've been trying to use Wings as the base of 3D printing, since I like the interface far more than what Blender offers, but at this rate even on the latest version booleans fail far more often than they succeed, and without it Wings loses most value as a modelling tool.
And while I'm at it, where the option to rename the axes so X, Y, and Z correspond with the standards that 3D printers use?

I just ran into the Coplanar faces message. Not sure about these and how to find them.

You can not have parallel faces when doing boolean, move the offending faces sligthly.
