Yeah definitely Michael - my primary aim is to get rid of some of the bloat that goes along with something like Revit - I would really only need the soft for drafting. Rhino is a good call as used so prevalently in this industry it seems but I wouldn't personally use it for drafting probably - DraftSight looks promising!

Depending on how in a hurry you are, I would just wait for Michael's implementation.
I have a feeling it will be the simplest option for that kind of job.
Keeping revit for the moment would save the time/frustration involved in learning and using another software.
If you have even a "low tablet" with not many hard memory you can use something like https://www.realvnc.com/
and like this run any programs on your tablett! ;)
It's truely amazing to run Moi3D like this!
You can also put an OTG connector for put a mouse 3 button + wheel on your Tablet ;)
