Question

Implement Component Dimension Referencing using Session ID in 3D Assembly Notes/Annotations

Why can’t assembly level annotations / notes reference component level feature dimensions using the part's Session ID like you can in 2D Drawings, this functionality works perfectly fine in 2D drawings but does not work in 3D annotations. Example: Calling out a C-Bore depth at the assembly level and using &dxxx:y to reference the depth of the C-Bore that is driven by dimension "xxx" on component with Session ID "y".

This is confirmed to not currently be possible see, https://www.ptc.com/en/support/article/CS93719

There are several possible work around but being able to reference a component dimension directly is less convoluted and it is already possible in traditional 2D drawing environments.

    Thanks for letting me know, I didn’t see the option for Topic vs Idea when creating the post. I’ve re-submitted it as an “Idea” but it said it will post subject to moderator approval.
