Working with the Extras Menu RoadRunner 229
10.4 Common Extras - Shift Reference Line
Description • When staking-out or checking different layers of the road strata, such as the sub-grade,
gravel or asphalt, it is often found that not all of these layers are available in the design.
For such cases RoadRunner offers the possibility to apply either a negative or positive
height shift to the design values.
Availability This menu function is available to the following stake and check methods:
• Slope, X-Slope.
The Shift Reference Line item of the EXTRA menu stays disabled until the first meas-
ured position is available. The current chainage Chainage is used for the cross-section
shown to pick the reference line.
Example In this example a gravel layer with a thickness of 10cm should be staked-out. Therefore a
negative vertical shift to the final design surface is applied. This shift is applied in the Selec-
tion Wizard by adding a vertical shift of -10cm. As shown below the selected X-Slope is
shifted by 10cm.
When staking-out the newly shifted X-Slope, the original
left edge of the shifted X-Slope is of little interest and it
is the intersection with the left end slope that is of
greater interest.
