Additional Information

Known Issues

This app uses the .NET API function FindXYAtOffsetAndElevation to determine the height of the section view. Due to the way Autodesk has implemented its functionality, if the elevation range of the section view is set to Automatic, the lines drawn may appear too short as the function returns the height of the section itself and not the height of the grid.
