Convert a blender model into a CAD drawing (NSFW)

Okay so I have been approached by an inventor who has asked me to do a mock up of some sketches he had.
So the 3d renders are complete and he is really happy with the result, as is the manufacturing company.
However they now want CAD drawings with di mentions etc and I’m not to confident with how to do this?

There is a negotiable price on the project, and the model is very simple, however non disclosure agreements will have to agreed to up front

NSFW as the model is a female sex toy.

We were looking at around £40GBP for what should take an experienced hand an hour or so?

Please either email me or text me on [email protected] or 07851 962206 in the UK

You could try getting a 3d package that will open Inventor files, Inventor will turn any object in it into perfect cad drawings.
