I have done a search of past threads and what I am looking for is reference or insight on layer management. We are an Architectural firm that does some of our projects in phases lasting for up to two or three years between phases. The architect in charge does some of the work himself and he gives some of the work to drafters as needed. Bottom line is there is no continuity of one or two people on the job.
The architect has noticed that lately layers are turned of or not visible when plotting different sheets at different times. I have done a little work with Express Tools - Layer Manager, Layer Groups, and snapshots in the Layer Dialog. These drawing are of the old variety having no 3d properties or 3d blocks. Has anybody come up with a system of layer managing using one or all of the tools above?
