Create Masking Region

[Anonymous]

How to create a masking region with the Revit API?

Masking Region appears to be a flavor of Filled Region with "is masking" set to true but it is a read only property and FilledRegion.Create requires a valid type ID which masking regions don't have. 

Suggestions?

Unless something has changed in the last 4 years, I'm guessing it's still not possible as I don't see anything in the SDK.  Happy to be wrong about this but thought I'd save Jeremy the effort of digging up his own post. 😉

I'll post it on Ideas if it's not there already.

You can filter out ElementTypes of BuiltInCategory Filled Region and use one of them as the ElementType. Or you can create a new FilledRegionType by duplicating an existing one, then change its parameters to make it looks like a masking region and create instances of that specific type. Would it work out?
