I would find it very useful to be able to add project level parameters.
E.g.
Let’s say there is a common material which is used in the design but the thickness may still need to be agreed. Designer can take steps to parameterise this at the project level and make provisions in designs within the project for the possibility of this value to changes.
Currently, the user needs to go into each design and make manual changes, and in my case this was time-consuming.
The parameter updates to an individual design can take place when the user opens a design within the project.
I also believe this will encourage people to use parameterisation features more often.
