I have an assembly of mine comsisting of two enclousres filled with a variety of parts. About 3 levels back of the final assembly, the entire assembly is moved to the left side of the screen when I click "Zoom to Fit." So, each assembly that calls in this subassembly is also shifted to the left. There is nothing to the right of the assembly that I can click to get rid of. Please let me know if you have any advice. Thank you.
