Most obvious thing is missing: Dimensions!

[Archimedes]

Where are the dimensions of objects? I want to simulate a system where the parts have specific size differences eg a circle 0.8, a chain 5 (whatever unit) and also objects at specific distances in order to work. How can I do this in Algodoo?
I also need to adjust the length of the chain -seems impossible.

I just found that I can set the exact dimensions (sort of) & distances when creating an object if I set the grid on, snap on, at base 10 (for metric) and by holding Alt key -but not for the chain, or rope. Also how can I CHANGE he size afterwards, and see the object's dimensions in properties (without counting the grid squares)? How about placing an object at exact degrees (angle measurement)?

Open script menu - it all there.
pos, size, angle, radius, etc
