(This functionality is available with the Profiles and Design Module)
The instructions for entering a point can be either by offset and elevation, offset and grade or elevation and grade. There are five options for entering the above combinations.
How the instructions are entered is controlled by the Mode column. The Mode column shows an icon which when pressed will step through the five available modes. The left mouse button will take you forward through the modes the right mouse button will take you back.
| Mode | Function |
 |
Offset and Elevation. Only the Offset and Elevation fields will be active in this row, the grade will be computed from the offset and elevation entered. |
 |
Elevation and Grade. Only the Elevation and Grade fields will be active in this row, the offset will be computed from the elevation and grade entered. |
 |
Offset and Grade. Only the Offset and Grade fields will be active in this row, the elevation will be computed from the offset and grade entered. |
 |
Grade of Previous Line and Elevation. Only the Elevation field will be active in this row, the grade of the previous line in the template will be used in conjunction with the elevation to compute the offset. |
 |
Grade of Previous Line and Offset. Only the Offset field will be active in this row, the grade of the previous line in the template will be used in conjunction with the offset to compute the elevation. |
The offset is always considered to be positive away from the reference point and negative towards the reference point. Offset values are always relative to the previous point in the template.
The elevation is always considered to be positive up and negative down. Elevations are always relative to the last point in the template.
Grades are considered to be positive when rising and negative when falling. The entry format of the grade is dependent upon the settings in Configure/Units.
The first row is always considered to be the location of the start of the template. If you want the template to start at the reference point then the Offset and elevation should both be set to 0.00 (default condition). Any other entry will shift the template to that position.
If the option of Grade of Previous Line and Elevation is used and the grade of the previous line turns out to be horizontal then the resultant offset and elevation will both be 0.00.
If the option of Grade of Previous Line and Offset is used and the grade of the previous line turns out to be vertical then the resultant offset and elevation will both be 0.00.
If you wish to use the reverse of the grade of the previous line then the offset or elevation should be entered as negative values.
Each time an elevation, offset or grade is edited the graphic display of the template will be updated to reflect the change.
