My company provides laser scanning and modelling services. I typically work for architects and engineers directly, however I have a tender to close that bids directly to General Contractors. I have no problems with competative situations, however, like everyone else, I do like getting paid on time. One of the General Contractors that I have to bid to is netorious for not paying or paying very late in the game.

Is there a way to set a key or command or some macro script into Revit 2013 that is timed to lock the .rvt drawing after a certain number of days after I electronically deliver my work that renders tha file invisible, or shows some pop up screen that requests the user to insert a "payment key - contact the provider at this phone number", then if paid, the key unlocks. If not paid, no access.

Thanks,
Leslie
