Caveat – RevitLookup Cannot Snoop Everything

This clarification was prompted by the issue #35 – RevitLookup doesn't snoop all members:

Question: I tried snooping a selected Structural Rebar element in the active view and found not all of the Rebar class members showed up in the Snoop Objects window. One of many members that weren't there: Rebar.GetFullGeometryForView method.

Is this the expected behaviour? I was thinking I could get all object members just with RevitLookup and without the Revit API help file RevitAPI.chm.

Answer: RevitLookup cannot report all properties and methods on all elements.

For instance, in the case of GetFullGeometryForView, a view input argument is required. How is RevitLookup supposed to be able to guess what view you are interested in?

For methods requiring dynamic input that cannot be automatically determined, you can make use of more intimate interactive database exploration tools, e.g. RevitPythonShell.
