rjbecs,
The section/elevation tool draws a dashed line with arrow like
symbols at both ends. Start the line as you would any line
and when you end the line an eye ball cursor appears
which you use to indicate the direction and distance you want
the section to be drawn. After you have used the tool, you
can go to the window menu and go to open section/elevation.
You have play around with this tool a bit to get use to how it works
