I'm working in AutoCAD 2008 and am having a problem with the draw order command.
This particular project is highlighting process loops in P&ID drawings. We are taking a client's existing drawing and creating tabs to show different processes. In each tab we are copying the loop lines to a new layer, changing the VP layer color to yellow (for example) and changing all other layers to gray (so that the yellow stands out). My problem is that after saving the drawing and reloading it sometimes the gray lines are atop the yellow ones when they should remain below (where they were set with draw order). The weird part of all of this is that nothing seems to be constant. Some times I can regen and everything is OK other times not.
Since I didn't create the files I have no idea what strange settings may be in effect and have even less of an idea how to correct this. Any help would be greatly appreciated.
