New to Kinematics and trying to set up a moving simulation of a simple crank-piston asy. I have it constrained and have added cylindrical joints. I get an error stating "cannot be simulated. Add at least one command to a joint". Could someone help me get started.
The message says it all: you need to add a command in order to do the simulation.
Double-click the Revolution joint between the Crank and the fixed part, and click the ANGLE DRIVEN option on the bottom. This will add an input command (angle between Crank and fixed part), and hopefully complete all the information CATIA needs for the simulation.
