Solidworks and CAD file Import optimization

Basically I'm trying to switch over to blender from keyshot because blender has so much better rendering and animation capability. The Problem is I'm using hard surface models imported from Solidworks as STL and they shade smooth horribly and are triangulated models. I tried retopolgizing manually which takes far too long given how many components each model has. I also tried Quad remesher and other auto remeshing tools and they just don't work very well with hard surface CAD Geometry.

I think enabling people using CAD Models to more easily import and shade smooth their models would greatly increase blenders capabilities. that way people can produce engineering accurate models in Solid works and other cad programs and get the best possible rendering quality using blender
