StroocturalEngThu Mar 8, 2012 9:20 amIs there a list of all parameters with their descriptions available somewhere? Searching this help for e.g. "UOptIsFileMode" returns no results.
loboarchFri Mar 9, 2012 1:59 pmI am not exactly sure what list you are looking for. different Revit elements will contain different parameters. Some parameters are valid for certain kinds of elements and not for others. The parameters for the different type of elements are typically documented where each kind of element is covered. This particular page is about user defined project parameters which can be added to ANY object. The list here covers the types of information which can be contained in a project parameter on any object.

bettisworthnorthFri Apr 27, 2012 9:45 amIs there a published text that describes examples of parameter scenerios along with best practice on how they are used?
pattygaleThu May 3, 2012 6:04 amSteve Stafford of the Revit OpEd blog offers some excellent information about parameters with embedded examples. While some of the UI screenshots are now outdated, most of the concepts and examples are still valid.
