I’m working with a local drafter and I just can’t visualize what the house will look like from these flat lines on paper. Is it rude to ask for a 3D model?

It’s not rude, it’s necessary! It is 2024, everyone should be working in 3D. If they can't provide it, find someone else. Services like https://en.architector.tech usually provide high-quality visualizations so you can see exactly what you are paying for before construction starts. Don't approve anything you don't understand.
