I am working on big machine level assembly which consist of several sub-assemblies. When I am opening the top level assembly in "Light Graphic Rep" from Open menu, all sub assemblies will be loaded in "Light graphic Rep". When I go to File-->Manege Session-->Object list to see what is loaded and how, I shows that (for example) subassembly.asm is loaded as (Light Graphics Rep Origin: subassembly_asm.pvt). What is this .pvt file? sometime it creates .ol file. Some time it loads few parts in "Graphics or MAster Rep". don't understand whether "Light Graphics Rep" really works? how these .pvt and .ol files are created and what is the use?
Can this Light Grahic Rep be used to create drawings?
