For example:

A hobby forum member wanted a housing for a circuit board,- therefore he sent me a photo and a sketch from the circuit board manufacturer.

After measuring all the necessary dimensions, I started with the first drawings and send these back to the member.  

When everything was fine and feedback was ok, I started drawing 3D and sent the next pictures to the member.

One of the most powerful tool is the Browser 3D viewer for everybody! -->  Klick to view the 3D example

(Zoom, turn around and move the object with mouse buttons and mousewheel possible)

In this way, all precision and control for everybody is fully guaranteed.
