 Stake Station Interval:
When clicked on, your slope stake target is always a fixed point. It is the slope stake at the
specified station in the input dialog in all 4 methods. But if clicked off, the slope stake target point moves
forward/back station as you move. In User-Defined, the pivot offset and elevation is used regardless of station
position. In the other methods, the pivot elevation is recalculated dynamically as you move based on the known
information (3D points, profile, sections).
 Round Station:
This option applies only if you turn off “Stake Station Interval” and move to “fluid” slope staking.
If you “round” to an interval, such as 5, then the elevation to stake from is calculated to the rounded station value,
as is the up-down station position for the offset. Rounding only applies to the stored report—the target still moves
fluidly as you walk forward or back parallel to the alignment.
 Load Road Net File/Select Road Element:
Carlson Civil 2008 and Carlson Roads 2008 have the option to output
an "RNF" file, or "Road Net File", from the RoadNet feature. This file contains every centerline, cul-de-sac and
road intersection "curve return" treatment for an entire road network. For example, a complete subdivision road
system can be output as a single RNF file, and then FAST Survey can stakeout any element of the RoadNet file that
is loaded. Since the RNF file contains both templates and final sections, the Load RoadNet File option is accessible
when slope staking by Design Files and Section Files. If you select, "Load RoadNet File", it merely loads the files,
announces "Process Done" and all road files are placed into a temporary directory. You then need to click "Select
RoadNet Element" to choose the element of interest. The three choices are centerlines, cul-de-sacs and the curve
returns at intersections. For centerlines, the Center ID of the design template (if that method is used) is applied to
the horizontal alignment. Keep in mind that for cul-de-sacs and curve-returns, the position of the horizontal
alignment is set in RoadNet within Carlson Civil and Carlson Roads, and typically is set to the edge-of-pavement
alignment position. Slope staking will therefore use just the outer part of the template, for example, from EP ID
outward, to find that pivot point. If you re-load the same RoadNet File, the program warns you that the prior
temprorary files will be erased and new ones created. This is done in case you actually modified a profile or other
files in the temporary files, in which case you should use SaveAs in the appropriate command to preserve the
changes in a new file name. When you Select RoadNet Element after loading an "RNF" file, you can highlight any
element to stake, which then appear "dashed" when highlighted:
