Ok, I guess this one might be hard to implement but hopefully might worth to mention.
I am taken to believe that cad/cam system mostly implement the third angle projection method, which makes things simpler than the known as first angle or European method which implements the descriptive geometry method of Monge.
Although I am Portuguese I agree with this reality, as far as can understand, nevertheless I have faced situations where projecting a geometry using first angle would be easy.
e.g. when during modeling you need to project a reference level point/line of feature on a sketch laying in an orthogonal/quadrant plane to a sketch laying in a second plane which is not orthogonal to the first plane. See screencast included.
So... having said the above it will be more or less obvious that I wouldn't mind if I could just click Project Geometry 1st angle option 🙂
