Why is thickness not updating in a Sheet Metal reducer part?
I'm not sure if this is the "correct" answer, but I got it to work by adding Thickness@Sheet-Metal1 to the table and changing it along with PL Thick.@Lofted Bends1. See screen caps.
Add Thickness@Sheet-Metal1 to table. It's the last one in the list.
Edit in table. Not sure if it's necessary to use the PL Thick.@Lofted Bends1 or not, but it works if you change them both.
