How to create image as parameter in a family

Anonymous — Mon, 04 May 2020 12:34:30 GMT

Hi everyone,

I am trying to add a new parameter to a family, in order to get that I do this

var familySymbol = (FamilySymbol)annotation.ToList()?.First(); var famDoc = this._uiDocument.Document.EditFamily(family.Family); using (var trans = new Transaction(famDoc)) { trans.Start("Adding parameter"); var parameterType = ParameterType.Image; famDoc.FamilyManager.AddParameter("Symbol image", BuiltInParameterGroup.INVALID, parameterType, true); trans.Commit(); }

But a error occurs, "Instance parameter of image type is not allowed."

Can I add a image as a parameter using Revit Api?

The message is telling you that parameter types of ParameterType.Image can only be used for Type parameters, this is the same as in the UI. Therefore:

.AddParameter("Image 1", BuiltInParameterGroup.INVALID, ParameterType.Image, False)

Will work.

.AddParameter("Image 1", BuiltInParameterGroup.INVALID, ParameterType.Image, True)

Will not work.
