create parametric 3.0 m10, which stresses

[VOLPINO]

Hey, guys, I'm sorry, but I'm having a little trouble on marametric creo.
Has anyone ever come across family table construction to create pistons?
more than anything else I would like to know how I can insert in the positioning "course" the data of the stroke of the cylinder, so that when I call the piston chosen from the list of the family this data is updated automatically.

Hi.
it is not simple, but if you manage the parameters translation1_minimum_limit and translation1_maximum_limit the game is done, if you really are a fox you shouldn't have problems.

Hi, dani, thank you for the answer to my question.
but the strings you entered are crack functions?
I had tried to create relationships in the parameters and to enter the command in the course positioning data, but nothing, takes the command and turns it into a finite numerical value and not in a variable as I set in the relationship.
Anyway tomorrow I'll try to insert the two strings you gave me, then hopefully, I'll let you know.
