This is another Marionette object based on a symbol belonging to @barnes2000. (Thanks Scott!) He has built a bunch of cool crane and lift symbols. This one is an Articulating Boom Lift that has seven different rotation or extension articulations. Each has a Slider in the OIP that allows you to set its angle or extension. (See video.) This Marionette object works by placing the different parts of the Lift as symbols in the drawing at a particular insertion point and rotation based on the values of the Sliders. Each symbol has named loci that are used to locate the object in the drawing space and in relation to the other parts. The loci are on an invisible class (so don't delete the class from the drawing). The object updates pretty quickly for having so many variables. If you wish to share the object to another file, make sure that you import the entire symbol folder.
Unlike the Scissor Lift, this object is not built from hybrid symbols because hybrid symbols cannot be rotated around the x- or y-axis. If you wish to convert it to a hybrid object, you could place it inside an Auto Hybrid, but this will make it a much bigger object (memory-wise), and you would only be able to edit the object from inside the Auto Hybrid.
