In AC You got two ways to make what You described:
- GDL is for making objects used in AC, it something like programming in Basic and it is open for everyone,
- Add-on programming with C+. Also for everyone (and free) but you need more detailed information how to do it. In this way you could make plugin working inside Archicad.
