I'm having trouble with an exploded view and the explode sketch lines I've created in it.

I've done the initial connection lines and now attempting to drag lines where I want them to be.  After I move the lines/end points, they revert back to where they were & SW 2016 gives me this error...

Automatic Relations & Automatic Solve are turned on.  Doesn't seem to matter whether or not they are.

And the .....

is on screen, but not actually showing any red or yellow error constraints in the sketch.

Any thoughts?

Thanks!

Tim
