parameter units not changing to millimeters

[praveensai931]

Im trying to change project units from cm to mm even though it applies for entire project the steel structure dimensions are not changing to mm in edit type panel.

The Project Units are not automatically applied to Loadable Families. You have to manually change the units in each Family. Maybe there's a plugin out there that could automate the job...

Certain families have their units hard coded. The UC Universal Column is one of those and its units is CM (it also displays such units when other structural column families dont).

All other loadable families will change units as per project units normally (See GIF below)

probably a long shot, but what Discipline and Data Type are those parameters set to?

[praveensai931]

These are built in parameters with structural discipline and section property type

[praveensai931]

Any idea how to change the loaded universal column units ?

[praveensai931]

Any idea ehat plugin it is actually..?

I like to disagree 🙂 Opened a Revit 2021 project and had a look at the Project Units:

Then I open a Generic Model in that project and check the Units:

As you can see - they're not the same.

Now there IS a checkbox suggesting the Family should use the Project Units:

But it's greyed out for all units / families.

I did a quick search in the app store, but found nothing....

@Simon_Weel  Refer to the posted screencast. It should be self explanatory

@praveensai931 it is hard coded you cannot change it unless you know a little bit of coding API. This family is most likely using custom UnitType Enumeration. Revits API allows user to explicitly disable unit conversions for a field using UT_Custom and/or DUT_CUSTOM

[Simon_Weel]

Ah, ok, I misunderstood. Anyway, it IS pretty annoying loadable Families don't sync their units settings with a project.

Post your family here!
