Hi Ljiljana
We have template kits available at
https://www.bim6x.com/solutions#bim6x-template-kits.
The BIM6x Starter Kit is free for ArchiCAD 18 and anyone downloading it will be eligible for a free upgrade to the AC19 version, which will then be priced at $99.
I recommend you download it to see what can be achieved with a powerful ArchiCAD template. It's customisable and as a full kit it comes with an example project, a BIM manual, work environments, and more.
Good luck on your ArchiCAD journey! You'll never look back.
Cheers,
