Changing Dimensions, but how to lock?

@ Sanctuary. Yea… My bad then, it’s not here in edit mode and you have to jump into Obj mode then (and apply scale afterwards) so it’s more clicks and whole object instead of one edge (while it gets desired length). Then again in which coords you scale that edge, Global, Local, Normal or Custom? Edit:Oh. It’s settable on F6…Did not notice that.
I somehow was still in the OPs Scale Object mood…

Yeah, that’s the problem that force to go to the F6 “overcomplicated” workaround (at least before i learned of the " = " ) , the lack of scale/dimension in the N panel when you’re working in edit mode.
Maybe there’s an addon for this, but i have not hunted for one yet so no idea.

Lets see. Maybe Psy-Fi will de-obfuscate this overcomplicated thing somehow ;).
