Drawing a Template Surface - General Procedure
NOTE
The following steps describe how to use the Draw Template command to
draw a basic template surface.
To draw a template surface
1 Create and set a new layer for the template items before starting.
2 From the Cross Sections menu, choose Draw Template.
The following prompt is displayed:
Starting point:
3 Select the starting point by picking a point in the drawing or entering
coordinates at the command prompt.
After you select the starting point, the following prompt is displayed:
Select point (Relative/Grade/Slope/Close/Undo/eXit):
4 Do one of the following options to select the second point:
n
Use object snaps or absolute X,Y coordinates to accurately select the point.
n
Type R to select the Relative option. This option changes the command
prompt to the following prompt:
Change in offset: (Grade/Slope/Close/Points/Undo/eXit):
The Relative option draws a line segment based on an entered change in
offset and elevation. For an offset to the left, use a negative value. For an
offset to the right, use a positive value. After you enter the offset value, the
command prompts for an elevation. For the change in elevation, use a
positive value to go up and a negative value to go down.
n
Type G to select the Grade option. This option changes the command
prompt to the following prompt:
Grade (%): (Relative/Slope/Points/Close/Undo/eXit):
The Grade option draws a line segment based on an entered grade and
change in offset. For the grade, use a positive value to go up and a negative
value to go down. Do not use the percent sign (%) when entering grades. For
example, enter a -2% grade as -2. After entering the grade, the command
prompts for the change in offset. For an offset to the right, use a positive
value. For an offset to the left, use a negative value.
n
Type S to select the Slope option. This option changes the command prompt
to the following prompt:
Slope (3 for 3:1) (Relative/Grade/Points/Close/Undo/eXit):
The Slope option draws a line segment based on an entered slope and
change in offset. For the slope, use a positive value to go up and a negative
value to go down. Do not use a colon (:) when entering slopes. For example,
enter a 3:1 slope as 3. After entering the slope, the command prompts for
the change in offset. For an offset to the right, use a positive value. For an
offset to the left, use a negative value.
