This script cleans specific data from all selected meshes.

Usage:
|
|
|
|
Select the meshes to be cleaned and run this script. A pop-up will ask
|
|
you what you want to remove:
|
|
|
|
- Free standing vertices;<br>
|
|
- Edges that are not part of any face;<br>
|
|
- Edges below a threshold length;<br>
|
|
- Faces below a threshold area;<br>
|
|
- All of the above.
|
|
|
|
After choosing one of the above alternatives, if your choice requires a
|
|
threshold value you'll be prompted with a number pop-up to set it.
