Can't change units of first user parameter created

Fully_Defined — Tue, 02 Apr 2024 16:23:23 GMT

I just found out the hard way that I can't change the units of the first user parameter I created. Unfortunately, I simultaneously found out the hard way that some formulas cannot use parameters that contain units. A double-whammy!

I can change the units of every other user parameter I create. Of course, if I could change the order of the parameters, I wouldn't actually care about the above two issue(s). But I can't, so triple-whammy!

Please make the first user formula created have editable units.

Also, why can some formulas use parameters with units and some can't? It's weird! I have parameters that include formulas with other parameters with units, but when calculating an angle with ARCTAN, it would not accept any of these same parameters.

It wouldn't be a problem if I could create a unitless version of a parameter that references the other parameter, but Fusion won't let me do that.

I attached a file for fun.

The reason you cannot change the units of the first parameter in your table is not because it is the first one but the fact that it was probably referenced in other parameters before you tried to change the units. Once a parameter is referenced by another, its units cannot be changed in the parameter table.

Not true at all. Try it yourself! Open a brand new design, create a parameter and then try to change its units. You can’t!

I thought that maybe it could have something to do with being in the top position in the table, but if I sort the parameters and the first parameter created ends up somewhere other than in the top position, its units still cannot be changed.

The attached video will show I can change parameter units until the parameter is is cross referenced.

For some reason, hours later and after updating and restarting, I am now able to do this too. There must be a bug in the MacOS version.
