Vertical Line Criteria
 
File Name: vl01.cri, vl02.cri ...

Reference Standard No. : N/A

Required Definition Files: standard

 
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.
The default value is 1.

Define as 1 when using the VL criteria for excavation limits for earthwork.
Define as 2 when drawing alignment centerlines
Define as 3 to place lines at the horizontal locations of elements found in a plan view file.
Define as 4 to place lines at the horizontal locations of elements found in the cross section file.

 
"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.
The default value is 0.

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.
The default value is 0.

              

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.
The default value is 0

 
"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.
Note: VL version numbers do not apply to this variable.

 
"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.
Note: VL version numbers do not apply to this variable.

 
"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.
Note: VL version numbers do not apply to this variable.

Example:

DEFINE_DGN "PROPOSED XS"\
   DGN = R2107b_rdy_xsc_l.dgn\
   LVNAME = Prop XS Finish Grade*, Prop XS Finish Grade CurbGutter

 

 
"VL FIRST LEVEL"

This variable is used only by configuration 1 (excavation limits).

When multiple vertical lines are being placed per cross section cell, this variable defines the level on which the first Vertical line will be placed. As the criteria moves across the cross section, the level is incremented by one for each successive line drawn.
The criteria always works from left to right. Therefore, the first line on the left side will be on the level specified by the definition of "VL FIRST LEVEL". For example, assuming the variable is defined as 30 and a total of 4 lines will be drawn, the rightmlost line would be on level 33.

The default definition is 30.

 
"VL01 LVNAME"   "VL01 LEVEL" "VL01 COLOR"   "VL01 WEIGHT"   "VL01 STYLE"

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:

 
LVNAME  DEFAULT
BYLEVEL COLOR   0
BYLEVEL WEIGHT   0
BYLEVEL STYLE   0

 
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:

"VL01 LBL TEXT HEIGHT"
"VL01 LBL TEXT WIDTH"
"VL01 LBL TEXT ROTATION"
"VL01 LBL TEXT FONT"

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".
