The catch slope criteria is used in conjunction with criteria types that do not connect to existing ground, such as curbing criteria. It draws a connecting slope, from the termination point of the previously included criteria, to the existing ground line.

The features of this criteria include the option of variable slopes, fixed fill slopes, fixed cut slopes or utilization of a DEFINE_DGN element for location of the slope stake point. These features are controlled by the designer via user defined variables.

Variable slopes are determined by using the standard defined cut and fill slope warrants. The tie point of a 2:1 slope is established and the fill height or cut depth at that point is compared to pre-defined slope warrants (CUT 2TO1 WARRANT or FILL 2TO1 WARRANT). If the height or depth is less than the warrant, the tie point of a 3:1 slope is considered in the same manner (CUT 3TO1 WARRANT or FILL 3TO1 WARRANT). If the height or depth is still less than the 3:1 warrant, then a 4:1 slope is tested. And it continues till a satisfactory variable slope is established that is not flatter than 6:1.

"CS01 CUT SLOPE"
Define as the desired cut slope value, if /when the origin point is in cut. The criteria will set a variable cut slope when this variable is defined as zero. The variable slope value is determined by testing the depth of the cut against the standard defined cut slope warrants.
Default definition = 0.

"CS01 FILL SLOPE"
Define as the desired fill slope value, if/when the origin point is in fill. The criteria will set a variable fill slope when defined as zero. The variable fill slope value is determined by testing the height of the fill against the standard defined fill slope warrants.
Default definition = 0.

"CS01 USE CATCH POINT"
When utilizing a SLOPE CATCH POINT element to set the cut or fill slope, define this variable as non-zero.
Default definition = 0.

"SLOPE CATCH POINT"
This variable is defined via a DEFINE_DGN statement, and specifies the symbology of elements in a plan view graphics design file representing the desired horizontal location of the slope tie point.

"CS01 MAX CUT SLOPE"
"CS01 MAX FILL SLOPE"
Use these variables to over-ride the default maximum cut and fill slopes. The default maximums for both cut and fill are 2:1. If the required maximum is 3:1, define as 3.

"CS01 USE CATCH POINT"
When utilizing a SLOPE CATCH POINT element to set the cut or fill slope, define this variable as non-zero.
Default definition = 0.

"SLOPE CATCH POINT"
This variable is defined via a DEFINE_DGN statement, and specifies the symbology of elements in a plan view graphics design file representing the desired horizontal location of the slope tie point.
SLOPE CATCH POINT is a global type variable. There are no corresponding local versions.

"CS01 WIDENFORGUARDRAIL"
When CS01 WIDENFORGUARDRAIL is defined as 1, the criteria will widen the berm, in fill, for guardrail where warranted. If defined as 0, no consideration is given to guardrail widening.
The default definition is 1.

"CS01 WIDEN BY GUARDRAIL LINE"
When defined as non-zero, this variable causes the criteria to check for presence of guardrail elements in a plan view graphics design file. If found, it's horizontal location is used to compute the guardrail widening warrants. Guardrail widening is then performed without regard to cut or fill conditions.
The default definition, taken from the global variable WIDEN BY GUARDRAIL LINE, is 0.

"GUARDRAIL LINE"
This variable is defined via a DEFINE_DGN statement, and specifies the symbology of guardrail elements in the a plan view graphic design file. When used in conjunction with WIDEN BY GUARDRAIL LINE, shoulder widening is performed.
GUARDRAIL LINE is a global type variable. There are no corresponding local versions.

"CS01 DRAW GUARDRAIL"
When defined as non zero, this variable will cause the criteria to draw guardrail on the shoulder when guardrail widening is performed. The purpose of this feature is to inform the designer where widened was performed.
This variable is the local CS version of the global variable DRAW GUARDRAIL. The default definition is 1, therefore guardrail will always be drawn by default. To turn off the drawing of guardrail, define this variable as 0.

"CS01 FIX FILL SLOPE BY GUARDRAIL LINE"
When widening by guardrail line element, the criteria will also fix the fill slope according to the value of this variable. Note that the slope value of this variable will over-ride the "CS01 FIX FILL SLOPE" variable in the presence of the guardrail element.
Therefore, if 2:1 fill slopes are desired in conjunction with guardrail widening, define this variable as 2. When left to the default definition of 0, fill slopes will be variable, unless the "CS01 FIX FILL SLOPE" variable has been defined.

"CS01 FILL WIDEN HEIGHT WARRANT"
This variable defines the fill height warrant for guardrail widening. The value is used in conjunction with the CS01 FILL WIDEN SLOPE WARRANT variable to compute the widening warrant. This variable is the CS local version of the global variable FILL WIDEN HEIGHT WARRANT.
The default value is 12 feet or 1.524 meters.

"CS01 FILL WIDEN SLOPE WARRANT"
This variable defines the fill slope warrant for guardrail shoulder widening. The value is used in conjunction with the CS01 FILL HEIGHT SLOPE WARRANT variable to compute the widening warrant. This variable is the CS local version of the global variable FILL WIDEN SLOPE WARRANT.
The default value is 2.

The widening warrant is computed using the slope and height warrant variables as follows:

Widening is warranted if Fill Height > (((( Fill Slope - FILL WIDEN SLOPE WARRANT ) X 10 ) X 0.7 ) + FILL WIDEN HEIGHT WARRANT)

"SHEARPOINT LINE"
This variable is defined via a DEFINE_DGN statement, and specifies the symbology of linear elements in a plan view graphics design file representing the shear line. SHEARPOINT LINE is a global type variable. There are no corresponding local versions.

"CS01 USE SHEARPOINT"
Define as non-zero to use any of the shearpoint features of the criteria. Default definition is 0

"CS01 USE SHEARPOINT PROFILE"
Define as non-zero when the tie slopes are to be variable to a previously stored shearline profile/chain.

"CS01 SHEARPOINT PROFILE"
This variable is defined as the name of the Geopak profile to use on the shearpoint chain.

"CS01 SHEARPOINT PROFILE CHAIN"
This variable is defined as the name of the Geopak chain that was previously stored along the shearline.

"CS01 DRAW SHEARPOINT LINE"
Define as non-zero to have the criteria draw a representational vertical line at the shearpoint. This line will extend from the existing ground up/down to the the slope shearpoint. Default definition is 1

" CS01 SHEARLINE LEVEL" Default definition = 34
" CS01 SHEARLINE COLOR" Default definition = 0
" CS01 SHEARLINE WEIGHT" Default definition = 2
" CS01 SHEARLINE STYLE" Default definition = 0
These variables define the level, color, weight and line style to be used when drawing the shearpoint line, when the DRAW SHEARPOINT LINE variable is defined as non zero.

" CS01 SHEARPOINT NAME TEXT" Default definition = SP
" CS01 SHEARPOINT NAME LEVEL" Default definition = 57
" CS01 SHEARPOINT NAME COLOR" Default definition = 4
These variables define the level, color and actual text to be used when labeling the shearpoint. This label is used to store the shearline chain/profile.

" CS01 RESOLVE INTERSECTING SLOPES"
Define this variable as non zero to get the criteria to resolve intersections of standard slopes between shape clusters. See chapter on Interchange Design for more detailed instructions.
The default definition is 0.

" CS01 SHEAR AT SLOPE INTERSECT"
When RESOLVE INTERSECTING SLOPES is defined as non zero, and slope intersections are resolved, a non zero definition of this variable will cause the criteria to shear both slopes to the existing ground at the point of intersection between the slopes. If CS01 DRAW SHEARPOINT LINE is defined as non-zero, a representational vertical shearline will also be drawn.
The default definition is 0.

The following variables are local versions of global variables. They define standard level/symbology values that should usually remain static. These variables are listed here for documentation and thereby make them available for pre-definition over-rides.
