I use some very complicated sketches, shared across multiple parts in an assembly.

Today, without trying, I had my first ever fully constrained sketch.

It was a beautiful sight to behold.

Carry on.

Maybe your sketches are too complicated.  Just a thought.

Congradulations on the fully constrained sketch!!!! That's an extremely important acomplishment. So much so, that I encourage (actually I demand) that our designers fully contrain EVERY sketch. I also encourage them to keep the sketches as small and uncomplicated as possible. Now you need to make sure that the rest of your sketches are properly constrained as well.

ditto on both the previous responses...

sketches should be kept simple

fully constrain all the time

Can you attach a screen capture of one of these "very complicated sketches"?

[#6]

Yes, I would also be interested in seeing how my definition of a "complicated sketch" compares to others.

I also demand that all sketches regardless of how simple or complicated always be fully constrained.

For the sake of us who aren't experts, wouldn't it be a good idea to mention that there are reasons NOT to fully-constrain your sketch?  I think I remember that Adaptive & Flexible (parts, assemblies or features) must be under-constrained to do their duty.  Are there other reasons?

Sketches need to be 100% contstrained to control there behavior, when modifications are made.  Also, adaptive parts are contstrained, also 'flexible' parts.
