[Closed] Creating a CatParent with Maxscript

When creating a CatParent with Mxs what or how do you control the scale of the parent Hub.
I am simply using :-

MyCat = CatParent()

This creates either an invisible CatParent or one with no scale, which is to be expected as I haven’t told it how big I want it.
Altering the CatUnits Scale at creation or afterwards doesn’t alter the size of the Parent Hub and I can see nothing through Showproperties to control the Hub scale.

I’m probably missing something obvious here but forgive me as last night was a late one but for all the right reasons
