This command creates section files in one step. The horizontal
alignment for the sections can be defined by using picked points, a
centerline file or a
polyline. A section alignment (.MXS) file is not required
for this routine. 3D screen entities
or surface files (.GRD, .FLT, or .TIN) are used to define the vertical
alignment.
There are two options under Quick Section Methods. The Station
Series method creates sections perpendicular from the horizontal
alignment at a station interval. In this case, the horizontal alignment
represents the centerline. The Single Station method creates one
section along the horizontal alignment appends this section to the
output section file. In this case, the horizontal alignment represents
the alignment of the section.
For the Station Series method, there are settings for the Start
Station of the horizontal alignment, the End Station to stop creating
sections, the Interval for the stations, and the Left and Right Offsets
to define the section width. There are also options to control the
section stations to create. The Stations At Interval option will create
sections at the specified station interval. The Stations At Centerline
Points option will create sections at the special stations of the
centerline for the centerline transitions such as PC, PT points
For the Single Station method, the Station value is assigned to this
section. The Zero Offset Point chooses between using the starting point
of the horizontal alignment as the zero offset or selecting a point
along the alignment as the zero offset.
With the Source Of Surface Model set to Surface Files, the program
prompts for up to two surface files so that up to two section files can
be generated at a time. When the Surface Model is set to Screen
Entities, only one section file is created from the screen entities.
With Screen Entities, there are a few more options. The Descriptions By
Layer option will use the layers of the screen entities as the
descriptions for the section points. The Interpolate From Data Beyond
Section Limit will check for intersections with the section line and
the screen entities beyond the left/right offsets to interpolate the
elevations at the left/right offset extents. The Ignore Zero Elevations
will filter out screen entities that are at zero elevation. The
Interpolate Zero Offset Elevation Of Sections will create a section
point at offset zero by interpolating between the nearest section
points.
Pick starting point (CL-Centerline,P-Polyline): select a
point
Pick second point: select second point
Pick next point (Enter to end): press Enter
