Hello In my workflow I export sketchup files to other softwares that dont t support ngon with holes unlike sketchup. So I need to manually draw line to remove thoses holes. But scouting thoses ngon with holes is difficult, is there’s a way inside of sketchup or with an add-on to Easley find those…

A sample model, or at the very least an image, showing these ngons would go a long way to helping us help you.

First image : This is how regular 3D software handle holes Second image : this is how sketchup handles ‘ngon with holes Third image on the left it’s a regular ngon, on a right it’s the procedure you need to do in sketchup sobthat the ngon is not triangulated like crazy when exporting to other soft…

[image] Dododododiran: procedure you need to do in sketchup sobthat the ngon is not triangulated But you triangulated it?

no i want no triangulation at all, that’s why im asking if there’s a plugin in sketchup that can detect thoses special faces, so that i dont have any triangulation at all when exporting. [hgj] i just need to do this and everything will be exported fine

what exporter or importer are you using for what destination app… the chances are the problem lays with that process… john

.obj to blender, blender don’t support ngon-with holes yet, so i need to create regular n-gon firt in sketchup before exporting, im just searching a way to make this process more easy by maybe a sketchup plugin that can detect thoses types of faces ?

I agree with John ( @john_drivenupthewall ) that the issue must be either in the obj exporter or else in Blender’s importer, as SketchUp allows faces with interior holes without triangulation.

Is this an option? [extralines]

Check the options on the obj exporter and see if “triangulate all faces” is checked. Edit: Nope. Even with it non-checked, exporting a non-triangulated face to obj and importing it back into SketchUp generates triangulation. Looking at the obj file in Meshlab also shows 8 triangulated faces where…

and this is the result in blender, clean mesh

i just want to have a solution that may help me in my workflow
cotty solution was great for the left ngon with hole, but with ngons with multiples holes i think that its problematic
