My workflow is to 1st push it to layout so I can get proper dimensions. I might copy in a screen shot of a dxf, and or a photograph. For markups I am using the scrapbook.
If I really need to get crazy I will then screen shot the image out of layout into affinity publisher. This is when I need to paint over parts and add advanced text. I find that I can work faster in affinity publisher or designer than I can inside of indesign or illustrator.
