Editing STL files in SketchUp

[Imagining]

Found this Instructable on instructables.com and thought it might be of interest to some even though it is about 3D printing.

hello
this instructions are good that a user learns the basics of cleaning an 3D object.
But…..
A STL file can only handle tri´s (means polygons with 3 sides)
When you save the file again as STL this gives unpredictable results. I see some points in that example where a converting from quads in tris are making trouble.
What I means is that after saving the file as a STL again you can start again to clean it, because you can´t calculate what sketchup do while converting.
If the file format you need for printing or milling only handle tris you have to work with tris.
