I found in an other post (See here) the dimensions from top view. Would be nice also to get them from the back.
The drawing is a good help but I ended up measuring everything on the actual board I used. The sockets can move around prior to soldering as they are not an exact fit in the holes on the PCB.
You are correct a 3D dimensional drawing would be good but even then you would need good clearance around each component to allow for manufacturing tolerances.
