scale option is possible in assembly condition ?

I'm not using the latest version of SW (2016), but I don't believe scale is available on a normal assembly. However, you have a couple options.

1. Save the assembly as a multi-body sldprt and scale that
2. If the assembly doesn't have many parts, you can create a "Scaled" config in each part and use that in a "Scaled" config of the assembly.

Hello Vijay Gowda

Mahir Abrahim is correct, it isn't currently possible to scale an entire assembly without using one of the workarounds he described.

We have an open enhancement request for this:

SPR 446313 - There should be a scale option that scales the entire assembly
