BuiltInParameterGroup String to Enumeration

Anonymous — Wed, 25 Apr 2018 22:41:12 GMT

I am trying to create parameters from a list of parameters but I am running into an issue with the BuiltInParameterGroup.

I currently have the BuiltInParameterGroup as a string such as PG_CONSTRAINTS, but obviously that isn't working because the FamilyManager.AddParameter() function requriest a BuiltInParameterGroup and not a String.

Is there an easy way to convert that string into the BuiltInParameterGroup enumeration? I'm working in Python, so if anyone has any idea specific to python that would be awesome, but I can also try to figure it out if it's in C#.

Thanks!

That was definitely the first thing I did. I also made sure to search all of the forums for a Revit specific solution.

As I am fairly new to coding, the conversion to Enum is a bit confusing.

If I have a list of strings that point to the string version of a BuiltInParameterGroup such as ["PG_GRAPHICS", "PG_IDENTITY_DATA", "PG_CONSTRAINTS"] how do I link it to the integer value that is associated with the Enumeration? Is this a task where I need to define the conversion for each BuiltInParameterGroup?

Sorry if this is a stupid question, I can try approaching it from a different direction if this doesn't make sense.

EDIT:

Sorry if my question was confusing/elementary.

For anyone working in python that might run into this in the future, this is how I was able to solve it:

exec("parameterGroup = BuiltInParameterGroup.%s" % pg)
