Variable parameter via a inheritance can be calculate in family table but with error

Variable parameter via a inheritance can be calculate in family table but with error

I find this comportement very strange but i know that it's possible to drive a dimension with a parameter in inheritance:

1-PART A with dimension driven by parameter

2- PART B with PART A in inheritance and with variable parameter and relation but with error with = or ==

And with == i obtain this error

But when i put this parameter A in family table creo calculate the value with good value in each instance but with relation error

Why creo permitte to do this if not possible??
Many users test naturally to drive this...

The other metod is to drive a dimension via a inheritance part with a parameter

Thank you very much for your reply

Hi,

I am not inheritance expert ...

1.] I removed relation d18=HT_AX from 4cad_231222_option_wc.prt

2.] I created 4cad_231222_option_wc_inh.prt and added relation d18:***=HT_AX

This is difficult to evaluate without some actual models with the dependencies you are asking about. Please post some test models and indicate what version of Creo you are using. I would approach this type of issue as you would debugging programming code which can only be done with the code (the models).

 

PS

Did you really intend to label this as a generative design question? If not, change the label.

Hello Martin

Yes you have reason, usually i do it as you explained but many users try to driven parameter with a second parameter in inheritance part.
I will ask to ptc if it's possible to prohibit this action .

Thank you
