Generally this type of error occurs when a V7 version macro or MDL

application is run within a V8 or later version of MicroStation. Another

possible problem is the element type may be a complex shape that may have

holes or duplicate vertices within it. Try creating a new line and

re-patterning the line element. If this still does not work, there may be

some corruption or missing resource file issues with your custom program.

The program may be calling out a function that it now cannot find.
