Few Pipeline questions

Thanks for all the advice guys! It’s time to practice.
It’s good i like having fun with some 2D CAD projects. this might come in handy.
Dividing buildings into modules may come in handy but i like to give each structure a personal touch. I guess that it depends on a project you currently work on.
I know that i should store all objects for reuse purpose , but didn’t really think of modular buildings. I also have to try if it works for me or not.
Anyway , huge thanks for all given advice. I’ll try to use it as well as i can and maybe share progress one day.
Stay safe
