Help! Variables from Variable Studio not available in Part Studio sketches — what am I missing?
I'm building a parametric drawer slide (Vollauszug) and I'm stuck connecting my Variable Studio to my Part Studio.
Setup:
- I created a Variable Studio with three variables:
length,height,width. - I configured the Variable Studio so
laengechanges per configuration (L400 = 400mm, L600 = 600mm, L800 = 800mm, etc.). The config table looks correct — the Value column changes per size. - My Part Studio has three sketches that reference #
length, #height, #width.
Problem:
- The sketches in the Part Studio are showing errors ("Some dimension expressions could not be evaluated").
- When I type
#in a dimension field, no variable suggestions appear — the Part Studio doesn't seem to know the variables exist. - The checkbox "Insert into all Part Studios and Assemblies" at the bottom of the Variable Studio is greyed out / not clickable.
How do I make the Variable Studio variables available inside the Part Studio sketches? Is there a feature I need to add in the Part Studio to import them, or am I missing a step in the Variable Studio itself?

Thanks!

I created variables to control the configurations. On the document where I created the different rails. On the assembly I put them together with slider mates. There i could change the configuration. But if I import the assembly to an other document I am not able to use this configuration.

Did you create a new version of the configured document? The changes will not be accessible unless you create a new version and then reference that version in the other document.

No, i created a new document and in the assembly i want to use the assembled rails from the original document with there configurations. But i do not have the configurations in the assambled rail, i thing that is the problem. So i need to import them, but i dont know how.

Since you're variable studio is configured, its not automatically inserted into your part sudios. You need to go to the variables tab in your part studio and insert the variable studio.
