Deselect using Perspective selection rectangle?

Hello, Im just trying to get to grips with modular building construction, and am making a fairly large building with many windows and trim pieces.

I have just found out about the Shft+Ctrl+Alt & Ctrl+Alt - ‘Rectangle selection,’ which is very useful, is there a way to use this feature to deselect portions of my selections?

Currently I am making buildings within groups, and turning off everything else, but this still leaves me open to accidentally select large portions at the other side of the model, and deselcting them per click is not ideal.

Any tips or advice?

Thank you :slight_smile:

I’d like to know this as well.
