Hi John,
Yes I thought that might be the problem - we have all done that many times!! We have put a request in to have a message pop up as a warning, so hopefully some future version will incorporate it. Unfortunately I don't think it will be in the next one though (V15) because the new version of Envisioneer (it's much more expensive parent product) has just been released and it does not have it yet, so TFP V15 almost certainly won't.
The lastest Envisioneer does have a new feature in the rendering area that allows you do re-select the cameras you have in the model view, which is very useful. It means you can select the different views and render them without going back to the model. Hopefully TFP V15 will include this. We will have to wait and see. The subsequent version of TFP usually comes out a few months after Envisioneer, so may not be many months away. If you buy V14 now they usually offer a very generous discount on the latest version.
TFP is quite intuitive, but, if you get stuck along the way, just ask here and you will usually find someone who can help. I am not much good on the technical computer side of things but Pat will usually come to the rescue there and get things sorted out. When it comes to rendering (which is TFP's main function of course) there are a number of others beside me, with many years of experience, such as Robert, Doug, Jack and others. Doug works with several other rendering programs, so can often suggest other ways of doing things if necessary, while Jack also works in TurboCAD and Envisioneer regularly and often pops in with little goodies he has found or divised there, that work in TFP also (such as the Measuring Stick

Anyway, there is always someone here to help when you need it and usually pretty quickly too.
