Recreating Assemblies in Pro/MECHANISM Design
Although it is possible to convert existing assemblies into Pro/MECHANISM, experience shows it is easier to recreate an assembly. One reason is that components often are assembled in a different order than what is required within Pro/MECHANISM.
Avoid conflicts between joint-axis settings and drivers. If joint-axis settings and drivers conflict, the assembly may fail when running the motion.
In most cases, the failure is caused by the driving trying to push a component beyond its joint-axis limits.
