Frank + wal
thanks both for your reply.
I was curious to know what happened to him as I recall he was a big fan of Cheetah3D, and used to talk about it and post renderings on architosh.com, which is a website for Mac based CAD users. Following on from Frank's suggestions, I checked out the modo forums and it seems as though he is now using modo. Looks like a nice piece of software, but $900 USD ? Yikes !
Thanks.
