Drawing on the model

when I draw anything on the model, it doesn’t let me see it, that is, it draws it but somewhere else.

What exactly do you mean? Share at least a screenshot of what you’re seeing or even better, share the SketchUp file.

This is all that is in your model. What is missing?

the image you shared, I can’t see it.

I will share with you what I see.

Have you tried Camera->Zoom Extents ?

To help achieve your goals, some time spent at the SketchUp Campus and at the SketchUp - YouTube channel will be very worthwhile. Both sites are from the SketchUp team. On the YouTube channel, pay attention to the Square One Series and Level UP series. They cover the basics for each tool.
