Is anyone else frustrated with the 'reference calculations' SW started doing in 2017 and 2018? It takes me 2-3 minutes to place a simple screw. It takes longer to place parts in an assembly. It didn't used to be this way. Placing screws should take no more than a couple of seconds, and placing a part shouldn't take any more than the time it takes to set up the mates. As it is, I have to wait for SW to finish dancing around the Mulberry bush, which takes at least minutes, if not 5 minutes, after an operation, then it takes multiple minutes to set the mates. It could easily take 10-15 minutes to add a part to an assembly and put fasteners in to hold it. This is completely ridiculous. I'm sure SW is doing something useful, but if it takes 2 minutes to place a fastener, and you have 30 or so fasteners to place, that's 30 minutes just to put some fasteners in. This is nuts. There has to be a better way to do the reference calculations. If I was able to do things quicker in previous versions, I should be able to do it just as quick in any version. Give me a way to turn the reference calculations OFF!!!
