Drive expression from PMI in NX7.5
Drive expression from PMI in NX7.5
(OP)
Hello,
Does anyone know if it is possible to have the "value" of a PMI annotation text (such as a Note or Balloon) drive the value of an expression?
To provide some context, we have a complex expression formula that drives the size of some geometry based on a value of 1, 2 or 3 (referring to specifications, so for example, typing in a value of 1 for an expression makes the geometry 300x100, or a value of 2 makes it 325x100...)
It would be handy to have a callout we can double-click and edit rather than delving into the expressions. Something like a balloon where we can edit the value would be perfect, but obviously this is derived as text rather than a parameter. Anyone have any thoughts?
Thanks.

We're fine with expressions and attributes, but this will have to be used by the general CAD-consuming population of the business...who I have less faith in not to get it wrong.
It just seemed like a handy idea - to have a callout that could control one or a number of expressions via a double-click.
Probably going to reevaluate the process, and use part families instead perhaps.

RE: Drive expression from PMI in NX7.5
Do you know that User Defined Expressions appeared in a special folder from the Part Navigator ? (have a look at the jpeg file)
So it's easier and faster than opening Expression Menu.
I hope this help if you don't already know this function

Unfortunately, John, we're stuck at 7.5! For the time being we will have to look elsewhere, but this is definitely a good method of finite control going forward.
Didier, this is also something we looked at. The more we thought about it, though, the more we thought about the requirement for specific values only. That makes it easy to see, but doesn't stop someone getting it wrong!
