Three-faced-edged external-faces now usually kept. [fixed TT's ball-breaker boxy mess
]Very interesting. I was stomped on this when I some time ago tried to make a remove_inner_faces script. Will have to snoop around the code. I'll probably dig up some more fun geometry - thing I got a batch of trouble-samples...
That was a quick fix BUT it will fail with very convoluted shapes that have inner faces like driven's pretzel ! I looking at an even better fix...

I'm still a little confused about the use of this plugin. Would it be of any value for anyone who is not doing 3D printing?

Probably not... but it does remove internal partition faces in a volume and fixes any 'holes'...

any form of additive or subtractive rapid prototyping will require good clean meshes to work from, 3D printing is just one of many format used on a day to day basis.
in more generalised modeling if you ever intersect or bool two solids and then try to continue with more advanced manipulations (readily available to SU ruby users) then chances are at some stage you've had to manually repair the mesh, this tool does it for you.
I was doing test last night using it between bool operations on the standard SU shapes, and was surprised. A. how many little holes it found and B. how many holes the bool tool had left.
Rendering engines that have been developed for solids will perform much quicker on a manifold objects
So if you never use need to modify after intersecting two objects, and only ever upload to google earth or make sheet material products then this type of tool is probably not needed...

took 15 mins but did a fine job this one TIG

Nice... apart from 3D printing. I think this can be used for healing models for rendering... when dielectric or SSS materials are used, there are a similar requirement as for 3D printing.

Can you elaborate? Curious about the logic of the renderer. Would it be similarly for meshes requiring displacement?

I know when I put a light source inside that dragon before xmas, light leaked out of all the holes in the mesh, so I had to fix them. cap hole didn't do it. you had ago at that one didn't you?
-
I did. I didn't have any issue with light leaks...but I used a higher poly version than most.
I wasn't sure if the plugin subdivided the mesh as well. I guess I should download and try. I keep telling myself I have to stop adding unnecessary plugins as it is becoming hard to deal with a plugins list three pages long!! Time to clean house.

Just remember while you are cleaning house, all mine fit nicely into a single menu item
TIG, this is a WAAAY COOL plugin! I have no idea how it works, but it has been on my list of plugins I'd like to write some day. This is invaluable for file conversion and mesh cleanup and 3d printing, and, and, and...

some time check, sorry the fonts so small.

....and I can't thank you enough for having the foresight to do that. I wish there were some way to better organize all the scripters plugins as you have with yours.

Here's v1.3 http://forums.sketchucation.com/viewtopic.php?p=218691#p218691
1.3 20100126
Trapped near colinear/planar points giving healing crashes.
Very small edges [0.1mm] now 'erased' by combining their vertices.
Orienting faces is now 'foolproof' - unless it's not made 'manifold'.
Now it only asks Yes/No to change to Xray mode if that's not on already.
Unhealed or Failed Fixes now reported, with failed edges shown as ... or -.- clines in Error Group.
[TIP: Move or Copy the error-group to one side to better see any errors - but if there are red/green faces obscuring the error dotted-lines showing problem edges etc then edit this error-group by treble clicking on a face till you have selected all then delete-key - now the error dotted-lines [clines] can be seen... manually edit and then retry 'manifold']TO DO: Get three-faced-edges external-faces to be retained in 'pretzels'.
groan......Feedback please...

I was about to post a drawing with timings for 1.2 and VolumeCalc2, so I'lll re-run it with 1.3, should be interesting..... cheers TIG, watch this space

Tig, did you see this post by Google's Tyler: http://forums.sketchucation.com/viewtopic.php?f=15&t=25175&p=218997#p218989
Might be useful to predict when SU will be able to create faces/edges?

Thanks - I did - hence the small line 'erasing' algorithm...

Hi all
can anyone confirm if they can see TIGtoolbar, while running manifold1.3, this drawing really slow compared to 1.2 and I just noticed I don't have the TIG-RRby icons in the toolbar which have never vanished before....
john
Check your files are in the same folders as shown in the original zip ?
It might be a bit slower running because the new algorithms ?
Try it one something simpler first ?? -

johnEDIT: TOOLbar sorted didn't update TIG folder in my rush to try 1.3, so that shouldn't effect performance, must be something else

I've got the reference somewhere if you want me dig it out, this is two two manifold objects sharing an edge...
basic are quicker, easy start...
