What is the reason that anyone ever thought it was a good idea to have the actual patterned components inside expandable 'elements' contained within expandable component patterns in assemblies? All this does is make for extra time and labor whenever the Inventor user needs to expand individual patterned component parts. Look to another design software (initials SW) for reference on how to do this 10 times quicker and better. All that is needed is for the patterned components to appear directly within the component pattern in the feature browser tree, nothing more.
