I did run it in a non-demo version, which was correctly reported: I have not tested it for both cases, though, since I do not have a demo version handy. UIDocument uidoc = uiapp.ActiveUIDocument

UIApplication uiapp = commandData.Application This is the external command Execute mainline code: String filename = Path.GetTempFileName() I implemented a little sample application TestDemoMode to test a simplified version of this idea. Some add-in commands should be greyed out or hidden in the ribbon bar in demo mode.Īnswer: You could try to save the model (after making a modification!) and then see if you get an InvalidLicenseException.It is a licensing issue, since read-only viewing should not occupy a license.Question: Is it possible to determine whether Revit runs in demo mode? Here is an example of using a related but different approach: the trick consists in attempting to perform a certain operation and gracefully handling a specific expected failure condition, in ths case a specific exception being thrown, to determine whether Revit is running in demo mode: We have seen numerous examples of performing a certain operation within a temporary transaction that is then rolled back to cancel it, such as to determine gross Here is yet another interesting example of an apparent gap in the Revit API that can be easily filled using a little workaround.
