Just for the record STL files) do not preserve native geometry. STL files break a part down into small triangles based on how fine the resolution was set when the STL file was created. One of the issues with STL is that if the part is very small, has lots of compound surfaces, etc, some of that detail can be lost.
STEP files preserve the original CAD geometry as surfaces and solids with no native resolution.
STEP or IGS are considered the preferred formats for exchanging CAD data, and as a Mech-E I prefer them, but anything is better than nothing.
No public wish lists :(
