What are your best practices for working with large DWG files?

Large DWG files can become difficult to work with when they contain thousands of objects, blocks, hatches, XREFs, and detailed drawings.

I’ve been testing the same larger DWG files in different CAD applications to compare practical performance during opening, zooming, editing, saving, and switching between layouts. ACTCAD was one of the applications I tested, and I was pleasantly surprised with how smoothly some of the larger files handled.

I’m curious about the experience of other CAD users here. What techniques do you normally use to keep large DWG files fast and responsive?
