This command calculates the offset and elevation at points along a polyline on a section grid. The results can be drawn on the grid or just displayed on the text screen. The offset and elevation are either calculated for each vertex of the polyline or at user specified points. This command can also be used as a section inspector. As you move the cursor across the section, the offset, elevation and slope are reported in real-time in a pop-up window.
The Prompt for snap toggle controls whether the command will present
the snap dialog
as you pick points to figure the offset and elevation at. The Grid
Starting Elevation
edit box allows you to input the beginning
elevation of the local grid that you are designing in.
Use the Scale edit boxes to set the proper
horizontal and vertical scales for your design
environment. The Label each vertex of grade
polyline option will draw the offset-elevation label
above each point in the selected polyline.
Section Offset-Elevation Settings dialog Choose the scales and base
elevation that match your section grid.
Pick center grid point [int on]: Pick the grid point at the
zero offset and base
elevation. The intersection osnap mode is on.
