I've got a sketch used as a projected curve, projected on an extruded surface. I've mirrored the project feature about a datum plane. This plane is normal to the sketching plane for the extruded surface, so the mirrored projected curve lies on the same surface as the original.
I want to make the mirrored project feature independant of the original. If you copy and paste something it's easy and I swear I could do it in 2001 and earlier with mirrored features. When I edit definition for the mirror there's a box under "options" I can uncheck that says "copy as dependent". If I uncheck it it stays dependent, and next time I redefine the mirror feature it is checked again. Does anyone now how the f**k to make it independent?
