Beginner seeking D3 Pick training videos and practical learning materials

Hi everyone,

I'm very new to Host Access and D3. We're currently working in a D3 Pick environment using the TCL (Terminal Command Language) prompt, and I need to learn everything from scratch.

I do have access to Rocket Software's D3 reference manuals, but they're quite large and a bit overwhelming to read cover to cover.

Could anyone please suggest the best places to find learning materials - especially video tutorials that cover basic concepts, TCL commands, creating simple programs, and understanding how everything works with real examples?

I really prefer videos or more practical, hands-on resources rather than just manuals.

Thanks so much in advance for your help!
