Extraction Project Properties from Revit

Question

Is it posible to somehow extract, export or copy Project Properties from Revit file using Revit Python Shell? And if yes, how difficult it is?

Answer 1

By Project Properties do you mean Project Information Parameters? This is a quick way to fetch a Project Information parameter in RPS:

parameterName = 'Project Name'
value = '- parameter not found -' # default setting

for parameter in document.ProjectInformation.Parameters:
    if parameter.Definition.Name == parameterName:
        if parameter.AsString():
            value = parameter.AsString()
        elif parameter.AsDouble():
            value = parameter.AsDouble()
        elif parameter.AsInteger():
            value = parameter.AsInteger()
        else:
            value = '- invalid value -'


print value

Edit: To fetch parameter values

Answer 2

I can't speak to the Revit Python Shell, but in terms of the Revit API it's pretty straightforward.

From your Document object, there's a "ProjectInformation" property.

So in C# it looks like:

Parameter p =
myDoc.ProjectInformation.get_Parameter(BuiltInParameter.PROJECT_NUMBER);

Parameter o = 
myDoc.ProjectInformation.GetParameters("MyCustomParameter").FirstOrDefault();

Side note: I've recently run into a spate of models that had no ProjectInformation property (null) on their Document. That's not good. I believe it can be fixed by running an Audit on the model - but from a code perspective you should be prepared for it (not like above! :) ).
