i just start working with Xrefs (worksessions) and like it a lot.
question: when closing a file containing xrefs i am askes to safe the worksession changes. i did so and a .rws file is generated. when reopening the 3dm, it does not contain may Xrefs and i have to reload the by attaching the worksession again. is this intentional? why? it seems unhandy to me.
another point that annoys me, is that the xref layers drop down to the end of the layer list after certain manipulations. to make them stay where i like them, i have to nest them into a layer. seems like a bug to me.
