[Plugin] Manifold v2.2
-
TIG- found the problem with the Bool'd groups -BT can create a group inside a group when bool-ing more than two groups, which I should have spotted in Outliner.
When manifold highlighted RED and said 'NO' I simply exploded the extra group and answered my earlier ?, it was much faster on the bool'd group and I assume would be the similar on a manually repaired group.
Note for users: The manual option also gives more control over the mesh shape at the torus/box intersection.
Basically TIG you've done a fantastic job on this, thank you
I'm convinced you, Chuck, and I won't be the only end-user's for this, it has soo many uses.
for now I'll keep putting up images that help or hinder, and get back to some bent text testing....
do you think it's ready for a wider audience yet, I'm planing on trying to do a tutorial when your happy?
ADD: it's what I thought re: tri/quads, just thought I'd ask

TIG,
I've got a couple of test on the go, I'll report on them when they're cooked.
some additional ?'s
which should be faster for manifold, simply continuing after fail or a manual repair than re-test continue
would it be possible to choose bothquad's and tri's as two separate groups, if you have two different post destinations for the object?
or would EraseCoplanar on a copy of a Tri'd group give identical mesh results?Manual fix versus Auto-fix depends on what needs fixing - making it right in the first place is the best bet
If you choose NOT to triangulate but then want a triangulated version then copy it and simply select all faces and run my [+tt's] tool triangulate_faces and you'll have the same result - uses the same code...

Even Likes Curves, but they will slow it down.

Here's v2.0 http://forums.sketchucation.com/viewtopic.php?p=218691#p218691
Glitch in health-check if very small edges in faces fixed...

v2 ? is this a major or minor update?

The tweaks were relatively minor - BUT as I am unlikely to make many more changes in the short-term I thought I'd mark it with '2.0'...

I have missed this new true gem!

When I use Manifold I obtain that ok
But When I kill or move the group red repair
I have the original copy with killed internal faces Yes ok
, but always segments on the faces! 
Does it normal? A simple box with 6 faces must be result ? No clean selection?

[attachment=0:2jmg80n7]<!-- ia0 -->bug.png<!-- ia0 -->[/attachment:2jmg80n7]This is correct.
The internal faces are removed by any edges they has forming part of the external envelope are kept.
If you want rid of then use one of the tools that removes coplanar edges...
It could seek to remove coplanar edges too ? -
Here's v2.1
http://forums.sketchucation.com/viewtopic.php?p=218691#p218691It now has the option to remove coplanar edges before triangulation, this will minimize the number of faces -useful if for example internal faces have been removed and their old edges are not needed to keep the external 'manifold' skin intact...

Cool now we have possibility or not to "clean" the model in the same time
-
2 volumes
copy movefor each selected (2 volumes) Intersect Selected
Groupfor each "group" apply Manifold
with same answers : Yes for the first question (of course)
and No for the others questionsCurious result is not the same!
Is that normal?

tested your .skp on mac and got two different results? first time I opened SU from your download file, 2nd time I opened it from inside SU, but that was the only thing I changed, something odd??
-
Manifold has to start somewhere in its checking - the first entity it encounters might not always be the same so you get differing results if there's a big mess...
Manifold was written to do specific job - check that a group is 'manifold' and if not try to fix it - it is so that when you export your model - e.g. to 3D-printer software - it will work. As it says at the start 'give us break' and try and at least offer it a set of geometry you hope might be manifold - it is NOT a boolean tool to merge volumes - it tries to decide which is the face to keep but sometimes removing or healing something changes the form - hence the colored 'report' group.
Before using 'manifold' try manually to get rid of at least a few known internal faces etc [x-ray mode + hide is good for this] - then the processing is quicker and more consistent...
-
I well understand
The only curious thing is that it not the same result for 2 similar groups inspected -
Thank you for your plug-ins!

Here's v2.2 - updated FR lingvo file [thanks to Didier Bur] and glitches with Tooltips and other strings deBabelizing now sorted...

Does/should this work with SU 8?
I'm not seeing any colours or new models created, even with the downloaded example but the example skp file is v7.
I suspect v8 needs a plugin like this too. If there is some other way to find doubles/duplicates/manifolds etc I'd love to know
Cheers

In v8 there are 'manifold' functions built in...

Really?
What are they called?
