Helical Rack
Use this node to model a Helical Rack in 2D and 3D. The rack is assumed to be rigid. Select one or more domains to make them a part of the rack.
A helical rack can be connected to a Spur Gear, or a Helical Gear through the Rack and Pinion node. A rack can be connected to a pinion only if they satisfy the Gear Pair Compatibility Criteria.
