| Summary
Vertical Line Criteria places vertical lines in the cross sections.Several options are provided through various DEFINE statements which make the Vertical Line Criteria very versatile. Among other things, VL criteria may be used to place centerline marks, right-of-way extents and Excavation Limits for Earthwork Summaries. |
||||||||
| Overview
The horizontal location of the vertical line is determined by the user. When used for excavation limits; if the line falls at a location where no proposed earthwork will be, it extends one meter (or foot) below the existing ground and one meter above the existing ground. If the line falls at a location where there is both existing ground and proposed finished grade elements, the line will extend far enough to cover both lines plus an additional meter (foot) above and below. |
||||||||
| User Defined Variables
"VL01 CONFIG" This variable specifies the desired configuration
type. Define as 1 when using the VL criteria for excavation limits for earthwork.
|
||||||||
| "VL DO NOT DRAW CL
VL" New!
When "VL01 CONFIG" is defined
as 1 for earthwork, a vertical line(s) is drawn at the centerline or at
an offset distance from the centerline by default. If the "VL
DO NOT DRAW CL VL variable is defined as 1, no vertical line
is drawn at the centerline or at an offset distance from the centerline. If value is 1 (centerline vertical line not drawn)
|
||||||||
| "VL01 CL OFFSET"
New!
When "VL01 CONFIG" is defined
as 1 for earthwork, a vertical line is drawn at the centerline by default.
If the "VL01 CL OFFSET" variable is defined
as a positve number, then a vertical line is drawn at this offset distance
from the centerline. One vertical line left of the centerline and one
to the right. If value is 5 (drawn 5' right and left of centerline)
|
||||||||
| "VL01 ADDITIONAL OFFSET"
When "VL01 CONFIG" is defined as 1 for earthwork, the vertical
lines are drawn at the slope stake point by default. The "VL01 ADDITIONAL
OFFSET" variable defines an addtional offset from the slope stake
at which to place the vertical line. |
||||||||
| "VL01 EXTEND DOWN" and "VL01
EXTEND UP" These variables control the height of the vertical line above and below the ground line (or the finished grade, depending on the configuration being used.) The default value is 1 meter or 1 foot. |
||||||||
| "VL01 CHAIN" and "VL01
PROFILE" When "VL01 CONFIG" is defined as 2 for drawing alignment centerlines, use these variables to define the chain and profile of the alignment. The vertical line will be extended up and down from the grade point computed on "VL01 PROFILE". |
||||||||
| "VL01 OFFSET CHAIN" New!
When defined and when "VL01 CONFIG" is defined as 2 for drawing alignment centerlines, use this variable to define the chain to label the offset distance from. Note that the offset distance is perpedicular from this chain and it is a COGO calculated value, not a graphical measurement. The default value is not defined. Example: DEFINE "VL01 OFFSET CHAIN" RP2A |
||||||||
| "VL DGN ELEMENT" When
"VL01 CONFIG" is defined as 3, the VL DGN ELEMENT is defined
with a DEFINE_DGN statement. It defines the level symbology of the plan
view element to be located on the cross section. |
||||||||
| "VL XSC ELEMENT" When
"VL01 CONFIG" is defined as 4, the VL XSC ELEMENT is defined
with a DEFINE_DGN statement. It defines the level symbology of the cross
section elements to be located for vertical line placement. |
||||||||
| "PROPOSED XS" When "VL01
CONFIG" is defined as 1 for excavation limits, the PROPOSED XS
is defined with a DEFINE_DGN statement. It defines the level symbology
of any proposed (or finished grade) cross section elements. The criteria
uses these elements to find the slope stake tie points. Example: DEFINE_DGN "PROPOSED XS"\
|
||||||||
|
||||||||
| "VL01 LVNAME" The level name defined the desire level symbology of the vertical lines. Color, weight, and style attributes are processed according to the level name "bylevel" assigments. Default values are as follow:
|
||||||||
| Labeling Features The labeling features of the VL criteria vary depending on the configuration used. Configuration 1 alone does no labeling. Label text parameters common to all configurations are as follows:
The variables "VL01 TEXT VERT OFFSET" and "VL01 TEXT HORIZ OFFSET" provide definable offset from between the top of the vertical line and the text label. "VL01 DECIMAL PLACES" provide means of defining the decimal place used for the station label when using configuration 2. Finally, the text label for configurations 3 and 4 are provided by the user by defining "VL01 LBL TEXT". |
