There’s a lot of assembly functionality in ST7 that has been kind of skipped over, or hasn’t had the attention it might deserve. There’s a new tool called Duplicate Components that is super powerful, but I haven’t seen a lot of coverage of it yet.
At Solid Edge University, it was demonstrated using a bulldozer engine with several engine mounts in various positions that you couldn’t place with a pattern. A few components had to be attached to the mounts at each point. So they were manually assembled on the first mount, and then the Duplicate Components tool was used to “pattern” the parts to all the other locations. Saves a ton of time and mates.
