Changing variable of part inside assembly

safa_alfulaij

Hello all.

I am new to OnShape, and trying to get my head around it. (I know parametric modelling from Fusion360).

I have a part, called WoodStick, that has 3 dimentions, length width and height. I'm trying to add the part in my assembly, and modfiy those variables from there, but with no luck.

In-Context doesn't create a snapshot for variable changes.

The idea is that I'm trying to create a wardrobe, and that WoodStick is the bottom support wood pieces.

Any help appreciated. Thanks!

Welcome to Onshape and the forums.

If you want to modify the variables inside of a part studio from the Assembly, you can create a configuration variable in the partstudio.
Now when you are in the assembly you can "Change Configuration" of the part and it will generate a unique configuration on the fly.

You should also consider that many of the pieces that make up a wardrobe can be designed together in a Part Studio. Modifying the WoodStick length would then modify all related parts parametrically. You should, however, use an assembly to insert multiple instances of WoodStick, rather than copy it in the Part Studio.

Thank you! I just didn't know that "Change configuration..." option changes those variables.

I'll look more into how to manage my parts and make assembly more useful!

It doesn't actually "change" anything in the part studio. It creates a "New Instance" of the part with the length you specify in the configured variable.

It's more like a virtual configuration. It only exists where/when you create it.

They save you from having to create a large table of configs, and let you make them on the fly.
But can be more complex than they seem at first.

But @NeilCooke is correct, this is one of those things that should like it is best modeled in the same partstudio.
