STL export issue

[Anonymous]

Here is the 3d model in autocad, everything looks good

Here it is opened in sketchup, notice the triangle artifacts in the lower 2 small indentations

I exported the stl out of autocad with the settings, viewres-20000, facetres-10

Friend, STL is a triangulated representation of a 3D CAD model.

Also... SketchUp isn’t inherently built for model production therefore it’s useful to check your SketchUp file for additional feature accuracies once it’s exported from the interface. Upload your SketchUp file into Meshmixer (http://www.meshmixer.com/) to check your file for faceting and fix any surface flaws.
