[Plugin] Manifold v2.2

driven

...easier than me starting over from scratch

Here's a semi complex one that sort of worked with 1.2, but on 1.3 it would only hang....

I might get this one printed in stainless, should only cost $100, and I can't think how else to make it.

I'm about to re-test it on my Mac and a PC comparison would show up if some of the problems are me or not...

If it fails first try, manually orient the reversed faces, then remove the internal disc on the bottom run and try again.

it 'should' remove the internal overlap on the bottom 2/3 twists (1.2 left these intact)

it might still make a hash of the end, Fredo's bend tool can be unkind to meshes.
I been running it without manual repairs

HI,TIG,is there have some differece between trigulaer face .rb and Manifold v1.4?

If the read the notes in the first post... 'manifold' does triangulate faces at the end, BUT it does so much more - it tidies the shapes to remove faceless edges, remove flaps, remove disconnected geometry, heal holes and very small faces, orient faces and then triangulates, and finally 'reports' on what it's done.

It is an attempt to automate the making of a 'manifold' surfaced mesh that will work properly when it's exported for use in a 3D printer, and some other 3D apps...

It's still under development...

You are the Man, TIG!

This plug in is a great great idea.

Here's v1.5 http://forums.sketchucation.com/viewtopic.php?p=218691#p218691
Various adjustments on speed, reporting, lingvo etc...
Still need to sort out 'pretzels' better...

Cheers TIG,
I was just logging in to say, I've set up one of my Macs, with a fresh instal and only a few basic rubies that I've triple checked are clean. Just to test Manifold. That way any log errors on my system console should be easily spotted, and you posted this, so excellent timing. I'll keep you informed. john

Can you PM that file so I can test it too...
Don't bother - I made one like it and I see the problem

inner face left

Fresh off the press, No error messages in console, had lots of info zipping through, had Pass dialogs, so all seems to be functioning, but all passed have inner faces? john

EDIT: I did the first with Transparency ON, so just in case it wasn't see the faces I re-did with Trans OFF, but the faces are still inside and the orientation is different from first

turned transparency off, orientations flip

Here's v1.6 http://forums.sketchucation.com/viewtopic.php?p=218691#p218691

Face making error fixed, 3-edge faces removal improved.
Sub-groups/Instances now within Group removed & reported.
Error reporting improved.

Hi TIG,
I think it's working really nicely now, lot faster, plenty of info, it still passes inner faces that don't necessarily break the 1 edge, 2 face rule.
There are only two '4-faced' edges in the original drawing and if a BoolTool, VWS, or a manual delete is done first, (as it should be) than manifold does a speedy and detailed correction, orientation and triangulation. I'm wondering if a simple pre-flight check that states, "I'm not doing this-there are inner faces highlighted that you need to remove first" or something less long winded, might not be in order. I'll PM you some other screen shot's as well.

Am I the only one testing this????

Here's v1.7 http://forums.sketchucation.com/viewtopic.php?p=218691#p218691

It now does a quick initial 'Health-Check' on the group and a dialog reports - it also temporarily shows any probable 'internal faces' in Magenta and faces adjoining probable 'holes' in Cyan etc...
If it's a lot of errors you can answer 'No' to not continue and then attempt to fix them manually, before trying again - or answer Yes to continue if there are no problems identified, or answer Yes anyway to try and auto-fix any problems [with a final error report and red/green/.../-.- highlighting in an "error-group"]...

TIG....do you sleep???

any chance this can be adjusted to not triangulate all faces? It is very useful for me to be able to clean up a model that I have carefully constructed so that I have consistent quads everywhere, which is what I need for sending into ZBrush for further detail modeling.

I know that Cheetah, too, triangulates everything when performing boolean functions, which I also find annoying. It is this, more than anything, that keeps me away from automated solutions for ensuring manifold meshes.

I'll add triangulation as a closing option ?

otb designworks

That would be quite useful, for me.

Now, how about a plug-in that cuts a model up into beautifully perfect quads? I'd pay cold hard cash for that one, too.

Thanks TIG!

Here's v1.8 http://forums.sketchucation.com/viewtopic.php?p=218691#p218691

Triangulation is now an option near the end - Answer Yes to do it...

TIG,
slight problem, when choosing Yes to continue after an 'initial health check' pass, it zapps everything even unselected groups.... both on badly grouped and clean booled groups, I'll do some more and send pics.

I'll see if it still happening in 1.8

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....
