I have been watching a number of tutorials on Youtube on a high end 3D program - Solid Edge - and became stunned by its complexity that was paired with a user friendliness that I was unaware of. This seems to be a contradiction, but in fact it just requires the user to adapt a different frame of mind when modeling parts. What this means, is that many relations between (sub) parts exists - similar to what we encounter in every day life - that we take for grated without actually being aware of it. The complex functionality was made to serve user comfort and increase construction options dramatically, which are features never seen in the over the counter commercial apps most people have installed on their computer.
