Pipes catalog error after editing the drawing units

[adam.bihi]

Hi everyone,

I'm having trouble editing the default units in this new drawing I'm willing to work on.

I just created a new project in the navigator and added a new construct for the architectural part of my plant.

Then I'm trying to edit the default units in my drawing using "units". Once I do so, I can't acces to the german pipes catalog. What I would normally get would be a catalog of many types of pipes. But once I change the unit from Meter to Millimeter, I get the following error message:

"The current catalog contains parts, that can't automatically be added in this situation"

Allowing AutoCAD MEP to rescale the objects or not doesn't change anything.

The error keeps popping up. I can only have access to the catalog if the default unit is Meter.

Any idea what could be the cause of this and how I can solve it? Or some workaround maybe?

Thank you very much.

Adam
