While I was working on the section editor,I forgot to close the s.e. view and I saved&closed the dwg.After I opened it, I could't see the plan,profile view.I saw some parts of the data .(dwg has alignment,profile,assemblies and corridor data but I can't see, I have some problems about viewing) I tried to open and close the section view editor; but it can't solve the problem.I follow these steps below;1.Ucs >world2.View>3d view>top This time plan is ok, but the section editor not ok.As an one more solution, I open a new dwg, then I copy and paste all corridor data into it.This time I can see all things ok, but I am not sure this new dwg can reach my shortcut data.I don' t want to use this style.Do you have any solutions?thanks
