I really been digging the app, but how do you guys handle making revisions on things? Since there is no inherent 2d shaped that are being saved, how do you say go back and change the length or size of a part of an object that your made in the beginning?

Istvan mentioned in another thread (share your ideas) that scaling is coming.
I think this is very important and needed.

I guess more than scaling is needed, I think we need to be able to post edit polys and shapes. If you 3D print you Gota be able to tweak measurements between prints.

You will be able to edit curves next week. But we are not going to add feature history for arbitrary modifications. But you will be able to remove faces later.
