Sketch says fully defined but it lies!

[hititfaster]

A friend called me with an odd problem: he's created simple sketch, dimensioned it and the info. bar at the bottom of the screen states 'fully defined'. 'Everything is black, including the line end points' he says. Yet, 'if you left click and drag a line, you can move it. Once you drop it, the dimension updates to whatever the new position is'.

My first thought was that the dimensions were driven: I checked and they aren't. I couldn't replicate the issue, so I did a screen share with him and watched him draw a square in a new sketch. He started his line on the origin, moved up, left, down then right to complete the square. He dimensioned it 50mm x 50mm, the fully defined message appeared, then he grabbed the LHS line and dragged it left... The dimension jumped to 75-odd mm.

To be honest, I don't even know where to start looking for a solution! Anyone?!

Turn off the following setting: Tools, Sketch Settings, Override Dims on Drag/Move

Wow, there's genuinely a setting for that?! I can't think of a situation where I might need it!

Thanks for the reply - very much appreciated.

If you do a lot of Top-Down design, you still want fully defined sketches, but need the freedom to move sketch segments around. Sometimes it's easier than double-clicking a sketch and editing the dimensions.

Have you read faq731-376 to make the best use of these Forums?

Sometimes you will fully define a sketch, but the FM says its under-defined. That is usually caused by a construction geometry end point not defined. But really who cares about an endpoint of a centerline. However if you use the option "Fully define a sketch" that end point becomes are real PITA.

@MadMango - OK, I can understand that. I do minimal top-down so haven't come across the issue before.
@SBaugh - Agreed, I'm just a bit anal about defining sketches. It's a pet hate that I've evolved. I've been using infinite construction lines as it often negates the issue.
