      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.

        acid test

        Am I the only one testing this????

          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"]...

              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.

                  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!

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

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

                                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

                                      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'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?

                                          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 groupinitial test picked up the buried group and then 'presto'

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