Rigid set in sketch

[edgray]

It looks to me as though you could use the constant length and constant angle constraint on each linear element in the sketch. If you have arc elements it becomes more complex. The fix or fully fixed constraints are too restrictive. This sounds like a good enhancement request for a new constraint.

I also just discovered that you can drag a group of sketch elements around by selecting the elements with a box then dragging them around.

Any help?
