select objects/faces with no thickness

Submitted by jsrocha on Tue, 2023-11-07 12:48

hi guys,
does anyone know if there´s a way to wrote a script that select only the faces (or objects) with no thickness? I need this to select glass faces with no width imported from a sketchup model. I mean, it´s a large scene and a considerable part of the glass object has no thickness. I can select by hand using some tricks, but i will be a huge effort.
Thanks in advance,

Jsrocha

Hello,I've got this script:

Hello,
I've got this script: https://www.mediafire.com/file/za9xj35r0h8kmqz/SimonScripts_SelectFlatOb...
it select Objects that only has one normals direction, it is not exactly a thickness "detection" script , but in your case it will select all windows that hasn't got thickness, it won't work if the glass objects are curved but for flat windows it will be ok.
it has an option to check only selected objects or all objects.
the downside is that it convert obj to poly to check for normals direction and doesn't filter instances out , so in the end every instances will be lost, i can add an instance check if you need to conserve instances.
