The problem I’m having with Sketchup Pro 2022 is that while rotating the camera around two objects one of them, the top one, keeps flickering making it look like it’s in the wrong position. See example below.
I’m not using any addons.

Set Camera > Perspective when you draw smoething. Use Parallel Projection for output 2D drawings.
It will also be useful not to have a component thrown 500 meters away from your model (Shift + Z).

As @mihai.s mentioned, it will be easier to model in ‘Perspective’ mode.
