Revit 2010 comes with a set of RPC content for your renders. But perhaps you want to make your own RPC content? Well, head over to http://www.archvision.com/ and register.

Then Login, and go to the menu item shown below:

Download and install the RPC Creator, and then enjoy making your own content!Have a look at this link for a getting started guide on using the program.

So I got a nice email from Avatech yesterday saying that I could download the full Avatech Utilities for Revit 2010 for free!

If you are signed up with Avatech, you may have got a similar email.

Otherwise, look into it at:

There is a ‘Lite’ version that anyone will be able to get for free.
