They’re not equal but there may be some similarities. I’m not sure. I have not used ProDesktop before.
From left to right:
Slider - allows a translation between objects along a specified axis
Clamp - locks objects together at their current orientation
Grasp - the point where the connection was made will attempt to stick to the other objects geometry
Slot - allows a translation along one axis and rotation on a perpendicular axis between objects
Universal - allows a coordinate frame to be created between two objects where any combination of six degrees of rotation and translation freedom can be added or removed.
Spindle - Creates a rotation between two objects. Think of a hinge.
and Ball Joint - a connection that keeps the relative location of the objects the same and allows any rotation
Yes, the clamp will keep it in place if connected to the world. If you’re wanting a static object in the physics simulation it might be simpler to mark it as kinematic, and ensure it has no transformation keyframes.
Unlike ProDesktop Bongo’s Connections will not bring the objects in the desired position. The elements of a mechanical structure need to be properly placed before the Connections are installed.
Rhino offers sufficient resources to do so.
Connection replace the function of the InverseKinematic joints. Piston Connection.3dm (356.2 KB)
In this model the crankshaft is made rotating via elementary Bongo keyframes.
The Spindles take care of the rotating bearings. A Slider keeps the plunger in a vertical move. A Clamp is used to attach the rod to the plunger.
The dark-pink decorations of the Connections are meant to show their position and illustrate their capabilities.
