Sub-Document Setup
Each subsystem document should have at least one part studio and one assembly associated with it.
The Stage 2A Basic Shooter is a simple subsystem with no moving parts. This contains only a part studio and a rigid assembly.
Subsystems with Multiple Degrees of Freedom
You may want to split subsystems with multiple degrees of freedom into multiple rigid assemblies. Each separate moving part of the subsystem should have a 'rigid' assembly (no degrees of freedom allowed for any part), while the top-level subsystem assembly only defines the motion between them.
Note
A rigid assembly, when inserted, is treated as a solid body with no mates calculated. It decreases load time in top-level assemblies greatly. You will learn how to integrate the origin cube into this system for easy parametric mates in assembly best practices.
For example, you could split an elevator document into one part studio and corresponding rigid assembly for each stage. The top-level elevator assembly would thus include each of the stage subassemblies within it and the slider mates.
The Stage 2C Slapdown Intake is a subsystem with a static portion and a pivoting portion. Functionally, this contains a part studio, a static assembly for the gearboxes and pivot, a rigid assembly for the arms and rollers, and a top-level assembly combining the two subassemblies.
The Stage 2D Cascade Elevator is a subsystem with a static portion and two subassemblies that slide linearly. This contains a part studio, a static frame/gearbox assembly, assemblies for the first stage and carriage, and a top-level assembly combining the 3 subassemblies with slider mates.
