Hi! I am very new to Revit & am on the learning cuve now with the "Ascent Training Manuals". I find that my save button is greyed out both on the ribbon and in the left dropdown window above "save as"! Any ideas why this is happening. The project does seem to be automatically saving. Just can't access that button! Using Revit 2013 Ultimate. Win 7 64 Pro.
Are you using Revit in Trial Mode or Viewer Mode? ( I think this is set when you install the program?).
Is your project a Central File / Workset enabled? ( Centyral on file server, local copy on workstation.)
Sometimes the save button will be greyed out if you are working in the central file and trying to save locally....
as I recall.
