Again.. hobbyists - but more to the point, it's perfectly possible to 'manually' do parametric constraints on moderately simple 2.5D geometries on the fly with a bit of logic using software that isn't necessarily built with that in mind. It's a cludge, sure, but if Fusion360 slows down 80% of your workflow where it's not doing much fancy, then that points to there being somewhere better, perhaps simpler, tools could be used. -ed Believe me - I wanted to like Fusion - I had the thing for a while and tried, but.. meh. It felt like a free product. At best.
