Regeneration Values
When you enter a regeneration value, a connectivity check is automatically performed. This ensures that only a valid value is entered in respect to regeneration values defined for other motion axes in the assembly. When the assembly fails to connect for the value entered, the component is made transparent and repositioned outside the assembly with dashed lines showing its place in the assembly. When this happens, undo the value entered or continue with the definition to ensure proper placement in the assembly.
