Hi krass,

Normally in CAD programs the type of thing you're looking for is called "constraints" and not "rigging" which is usually what it's called in animation programs.

Pilou is showing some of SpaceClaim's constraints mechanism there.

Maybe I have misunderstood what you are trying to do - I thought you wanted to edit the endpoint of a line for example and have the drawing change to accomodate the movement while keeping various measurements that you specify to stay the same, like same length on various other lines, tangency kept to a circle, etc... That's usually what is meant by constraints in a CAD program.
