Odd - I can't get it to error at all... :? Please 'feedback'.............

been trying to up load pics, site is slow, pics to follow

it's on both machines, 1.7 and 1.8

3 groups from Draw Shapes Menu, grouped, manifold_1.7and8, both give a pass
[attachment=0:19dcyp32]3 groups inside group_1.jpg[/attachment:19dcyp32]
Yes to continue....zapppp

Same 3 groups, exploded then regrouped is running as predicted on other mac at the moment, this site is slow from this machine....

something screwy going on with uploads, sorry it makes thing disjointed

I get no problems... but can you PM me that model asap, so that I have exactly the same starting point...

The 'no problems found' report is on any geometry that hasn't already be relegated to 'red'... looks like everything is removed BEFORE we do the health check - it's not a group inside a group is it ?

TIG,

they were groups inside a group, and got a pass, (they are all manifold) it only zaps them if you say YES,
the same thing happened after I BoolTool'd all 3 groups into 1 group, initial pass (as it should), but zapped if you choose YES, I only got the RED on that one drawing, I'll re run the first set-up and post the if no red is shown again.

I have just set a Bool'd group run that Passed initial and didn't blitz the drawing when I hit YES

It's on a pair of torus + geodasic sphere bool group, and it is running.

original set ungrouped, but not booled

and others work so smoothly

Here's v1.9 http://forums.sketchucation.com/viewtopic.php?p=218691#p218691

It now traps for 'No Geometry' inside the Group...

NO Zapping with 1.9... is it possible for the health check to report 'NO geometry to Check because the selection contains sub-groups'?

I'll try some other breakers I've been working on...

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?

driven

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?
un-intersected single group initial test picked up the buried group and then 'presto'

ADD: it's what I thought re: tri/quads, just thought I'd ask

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.

seems a lot quicker than before on this sort of thing

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?

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 ?

TIG

Here's v2.1
http://forums.sketchucation.com/viewtopic.php?p=218691#p218691

It 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

pilou

2 volumes
copy move

for each selected (2 volumes) Intersect Selected
Group

for each "group" apply Manifold
with same answers : Yes for the first question (of course)
and No for the others questions

Curious result is not the same!
Is that normal?
