Parameters in Dimensions

[amalloy]

I have a parameter with a relation set up to
automatically control the tolerance of the overall
dimension of my design. I need this parameter inside my
dimension so that it updates as soon as the overall size
of my design changes.

For some reason, when I put this parameter in the
dimension (as &PARAMETER), the actual value doesn't show
up, but name of the parameter does.

Is there any way to correctly do what I need to do?

Thanks in advance!

Just write a relation:

d_num=parameter_name

I can't get that to work. I need the tolerance to change,
not the dimension.

 

[dr_gallup]

tmp_num=parameter_name

Assuming it is a symmetrical plus minus tolerance. Use the switch dimensions button to switch between values and symbols so you can get the name correct.

Maybe I'm missing something, but that still doesn't seem to
work. I am using symmetrical tolerances. When I switch
dimensions, the tolerance comes up as "tpm0." I put that in
my relation, and nothing changes. The only tolerance that
comes up is exactly what I have typed in the dimension
properties. I have tried several different things with the
relation and the tolerance name and nothing wants to work.

I'm using WF5.0 and this drawing is part of a
configurator/drawing program that I'm building, if that
makes a difference.

I just created a new part with one dimension d0, symmetric plus/minus tolerance tpm0.

I created a parameter tol equal to 1
I added a relation tpm0=tol
I regenerated my part and the tolerance changed from the default to 1.

So it works, I can't tell what you ae doing wrong.

Is the paramete in your part or in your drawing?


Which part is active when you place the note?
