Files that are in that link are here too.
If you take 2 objects in assembly, use a constraint with a min max, then use a pattern array on it, you can drag the first two parts, but the parts in the pattern won't update without having to pressing the Manage>Rebuild all button every time you move things. As a program that is great for demonstrating complex physical movements, you would think this would be apart of the features... In my case, it would be of great usefulness to use this to demonstrate sets of moving parts in full series without having to copy everything hundreds of times and reconstrain them each. Plus it'll help reduce the amount of modifying each object later if I need to update a feature.
Proposed Solution: Please add rebuild all as a step after dragging... allow it to be a toggle switch over in Manage tab so it doesn't slow down the average user experience.
