ampersand(&) in relations window.

Hello,

 

I'm working with an existing assembly file and I have observed that they have used '&' before the dimension in a relation.

Ex: &d340:1 = FLANGE_WIDTH      (Here FLANGE_WIDTH is a parameter).

 

I want to know the use of '&' here, because I observed it works without ampersand in a different assembly file.

Re: ampersand(&) in relations window.

"&" is used in drawing notes to distinguish text from parameters. Someone probably carried this over and Creo obviously ignores it. There's no interpretation I see for it when used as a prefix in a model relation.

 

Using a "$" does have a significance to indicate the sign of the value is important. The default is to use keep the value positive and switch the direction of a related dimension.
