I would like the ability to create Pulley belt system:
- V-Belt (Multiple or single groove pulleys)
- Timing Belts
- Flat Belts
or Chains/Sprockets:
- Roller Chain and Sprockets
- Conveyor Chains (electrical conduit)
This feature would allow me to create and animate mechanisms with realistic movement. See the below discussion for reference.
