Linked Values won't remain linked

Linked Values won't remain linked

Linked Values won't remain linked

(OP)
I'm working on a part file that I've attempted to link dimensions to a global variable.  This part has multiple configurations which simply suppress or unsuppress features as needed.  I can linked values to the variable, but the links disappear when the model rebuilds.  I've been able to link values within a configuration, but the other configurations do not retain the link.  When I link the value in one of the other configurations the original configuration that I started with looses its link.

Any suggestions?  Are the limitiations, parameters or settings to linking to a global variable?

 

RE: Linked Values won't remain linked

How are you linking the variable?  Are you using a equation or clicking link values?  You may have to use an equation?

RE: Linked Values won't remain linked

(OP)
I've just been clicking link values.  There are roughly 25 features that use the same value.  I was hoping to avoid extra equations when I thought the link value should work.

RE: Linked Values won't remain linked

A Design Table can be used to link dimensions also, & when dealing with configs is the best way to go.

RE: Linked Values won't remain linked

Does the global variable change value between configurations?

RE: Linked Values won't remain linked

(OP)
No, the global variable should be the same for all configurations.  Each configuration is simply a difference of which combinations of the features that use the variable are suppressed or unsuppressed.

Could it be that suppressing a feature is the problem?  I'm not suppressing the sketch that contains the variable, only the feature (a cut revolve) that uses the sketch.  Also, I should mention that 24 of the features use a derived sketch with the global variable used to positon the derived sketch as well as the original.

I considered using equations, but that just seems like an extra step.  Linking values would intuitively seem to do the same thing, but I could be wrong.  I would use the design table, but again that would seem like an extra step.  I was using the design table to direct which features are suppressed or unsuppressed.

RE: Linked Values won't remain linked

Is this the only file you have that does this?  Have you tried making a quick test file and see if you can duplicate the problem?
