MIRROR ASSEMBLY DON'T UPDATE

MIRROR ASSEMBLY DON'T UPDATE

Hi everyone,
when I create a mirror assembly with File> Save As> Save mirror assembly and check the flag to keep the dependency because in case of modification of constraints or assembly features these do not update?
Only the individual components within the assembly are updated. It's normal?

There are two primary ways to save mirror assemblies. The way that you tried with save a copy and then the other method which is performed in assembly mode. The method you used will mirror the parts/features inside the assembly but the parts won't be placement dependent (constraints won't update). If you want your constraints to update, try using this method:

  • Open the assembly that contains the part/assembly you want to mirror
  • From the Component dropdown in the Model tab, select Mirror Component

You should see an interface that looks like this:

  • Select the part or assembly you want to mirror (Component reference)
  • Select the plane to mirror the geometry about (Mirror plane)
  • Enter a filename for the new part/assembly
  • Check the box to ensure the mirrored component will be placement dependent

  • Click Ok

With this method, you should be able to reposition the original assembly and the mirrored assembly will update because it’s symmetric about the mirror plane. The same is true with the components inside the assembly. Both methods for creating mirrors are useful. As with most things, it depends on design intent.

 

I hope this helps!
