[Plugin] Solid Inspector

I have tested some code and I admit that making the ends of a tiny edge coincident isn't working - as you are left with an edge of zero length [!] with two coincident edges too! Moving vertices to become coincident must be possible - the TT-vertex-tools ? I am stumped
The only way I found, was a method similar to how you heal edges, you make a temp edge and then erase it. That will merge the vertices located at the same position and remove the zero length edge.

Actually, there is some more to it. Here are a few methods I use in Vertex Tools 1.1 to heal geometry after manipulating vertices:

So that method[s] run after any tiny [0.5mm?] edges are shrunk to be zero by transforming the end vertex to be over the start vertex will then heal any 'small [zero width] holes' ?

Any zero length edge and zero size face should be healed (read: removed by SU's auto-merge feature).
-
But if you find some edges ~0.5mm long and merge the vertices that edge still exists as a zero length edge - SUp doesn't auto-merge them - also the previously separated other sides of the hole are now coincident and not auto-merged either!
So your code would remove the zero length edge by forcing an auto-merge BUT do the coincident edges then merge too? I don't have time to test it - but if it works it's the basis of having a tool to 'make solid' groups etc that have tiny holes -
OMG, THANK YOU THANK YOU THANK YOU!
I cant wait to use this too...combined with Artisan...OMG...FINALLY, I can do 3D
modeling without countless hours of error fixing (even when working large scale).
This is going to save days of my life...lol.
CHEERS!
<---swigs a brewski in your honor!

OK, I'm having the same problem as another user, Solid Inspector doesn't show up in the menu. I'm using Sketchup 8 (7 is gone), put the .rb in the plugins folder and also the library2 folder in the plugins folder. (In fact, now that I look at it, several plugins don't show up?) What am I doing wrong:

You ain't looking at the description of the plugin.
Not all plugins add menus to the Plugins menu. Check the info in the first post for how to use. -
As TT said... not all scripts appear in the
PluginsMenu - this one is set to load in theToolsMenu as explained on the tool's download page
that is UNLESS the "ThomThom's Plugins" menu is loaded by the scripttt_0000_menu.rb- then that submenu is added inPluginsand TT's tools all collect there ! [but that's academic as you don't appear to have file that inPluginsfolder, or the submenu it would make...]
So look in theToolsMenu...
If it's still not there come back to us... -

FWIW, you don't have the current cutlist plugin either.
-
OK, that worked ... as did the Solid Inspector, when I first clicked on the tool then used the controls. My bad. Still learning this great product. This tool solves a big problem that I've encountered creating solids - and will save me hours of time spent recreating solids that aren't really solids.
Thank you both.

OK, thanks for the heads-up on Cut List, but how could you tell from the picture I sent?
-
By the name. The current version would show as "cutlist.rb".
-
Just wanted to say: this plugin is the biggest thing to happen since hotdogs. Hurray for workflow!
-
Very, VERY impressive application! Thom you've made my work so much easier, and for that I am truly grateful. This "Error GPS" is remarkable, thank you so much for the amount of time and effort you've put into this plugin, in order of making everyone elses life T-H-A-T M-U-C-H easier. Merci mon amis !
Sincerely,
Kyle James

Now thatwas a proper "thank you".

Hi, kind of a sketchup newbie here. I am using this plugin to check my model for water tightness, but I am having trouble understanding the output. Would anyone mind looking at these screen shots and giving me some tips? Thanks!
-
In order to build a solid object, there cannot be inner faces (amopng other conditions). You have some - and that's still not the only reason as deleting the face in the screenshot below still does not fix it.
(Note that I have reversed some faces and smoothed the group generally...)
As it turns out, it was all inner faces. Did not take too long to fix: when you have some time, send ThomThom a cookie.
-
There are also some ungrouped lines that can prevent your model to be solid.That means that they are outside the group or inside the group with the solid subgroup.In your case they are outside the group.See picture.
