New to Catia - Need VBA samples & viewer advice

We are fairly new to using Catia. We have Catia V5R10. I was hoping a few people could send me sample VBA code for customizing / macros in Catia. Or links to good websites to help with catia VBA programming. Additionally we are looking for a way to be able to view LARGE catia product/part assemblies (automotive metal stamping progressive die designs) in a viewer for design presentation without having to have an active license of Catia available during the presentation. Any and all input is appreciated. I've found lots of viewers for V4 but few for V5 and so far none have been reliable for CatProduct files. How are you doing it in your company? Thanks in advance for you help.
