Coordinate Dimensions

[maurelius]

Hi,
I am having some trouble with coordinate dimensions in v18 SP12.

Up until recently I haven't had any problems but now I seem to get some strange behaviour.

After you add the base (0,0) dimension, the subsequent dimensions snap to it. The problem is that they don't always snap. If for instance I add a dimension that is not near the 0,0 base dimension (ie it is local to a hole, but not near the base dimension as in attached pic) it is pot luck whether it snaps or not; some do at the same distance from the hole as the base is from the geometry and some don't.

I also get irratic behaviour when I put in a jog - cannot move the dimension afterwards, the jog jumps when I try to move it, I cannot put the jog where I want to etc...

Has anyone else encountered this? Does anyone know what is causing this?

Thanks

Did you recently load a new service pack or a change to your system ?

No, nothing has changed. I've been using it the same way for years and it appears that other users have the same problems. We are all using the same templates and have the same settings too!!

Thanks

Coordinate dimensioning is a weird beast at the most. I've been working with SE since V4 so I've seen the up and downs of it.

I would recommend to update to V19 or 20. Coordinate in each has seamed to improve.

For you question there's really no easy answer. Basically your dimension will snap to where ever the zero at. If you get lucky, and SE is in a giving mode (yes SE has a mind of it's own at time i think), you meant be able to place a dimension in the opposite direction and it will create a snap point.

Sorry i couldn't be more help

I know what you mean with having a mind of its own!!

Thanks for your help.
