i'll do my best to explain the problem hope someone will undersdtand it.
I've installed the Revit 2012 and i have problems with the control lines.
every time i click on an option, for example if i click on a wall i've made and i want for example to modify something there are buttons missing. if i click to change the form the buttons are shown then all the buttons are shown....
I hope I explained it good enough
thank you all!!
This sounds like a problem related to Microsoft .NET 4.5 being installed on the PC. If you have .NET 4.5 installed you need to have Revit 2013 Update Relase 2 installed or you will see issue related to buttons not being displayed on the contextual tab of the ribbon.
