I have a Dogleg style conveyor Assembly that I want to exploded so that it is exploded by Subassemblies. We have always visualized and brokedown our conveyors by sections (different sections for different style) for the last 40 years. On the conveyor I'm working on now, it is made up of 8 Subassemblies (Tail, Lower Horizontal, Concave, Incline, Convex, Head, Drive/Take-Up, and Support sections. So, I want to explode the Assembly into 8 Subassemblies and balloon the 8 Subassemblies with their part number. Then each Subassembly will be exploded in its own drawing package (We use the A-1, B-1, C-1, D-1, ect; sub drawing package system). When I try to explode the Assembly, it wants me to pick parts within the Subassemblies. What am I doing wrong?
As usual, thank you for the free education.
