So this isn’t just a font thing, font is just an illustration/sketch of a letter. This happens also with SVG artwork that was converted and imported.
Other CAD programs have some kind of Curve Analysis tool, but even with that in this case overlap is so small and font has so much curvature it will overwhelm you with data.
The new feature you want in Shapr3d is to implement curve overlap indicator. Fonts for me it’s easy to figure out with the triangulate method.
Vector Artwork import is even more time consuming.
