Definitions  

Point 
Line 

Angle: The orientation of the line from the marker. The default value is 0 (zero) degrees (due east). The angle is calculated in a counterclockwise manner. Length: The distance of the line from end to end. The default value is 5 pt. Adjusting this value will change the length of the dynamic line. 

Polygon 

Size: The distance from the edge of the marker. The default value is 1 pt. Specifying values greater than 1 will create a larger dynamic polygon around the marker. 


Radius: The distance from the center of the polygon. The default value is 2.5 pt. Specifying values greater than 1 will create a larger dynamic polygon around the marker. Edges: The number of sides for the polygon. The default number is 4. Specifying a value of 3 will produce a triangle. Specifying a value less than 3 will produce a circle. Angle: The amount of rotation for the polygon. The default value is 0 (zero) degrees. 

Line 
Line 

Angle tolerance: The maximum amount of deflection from one segment to another at a vertex. The default value is 120 degrees. Angle values between 180 and 360 are interpreted the same as values between 0 and 180. Angle values of 180 and 360 are the same as 0 (zero). 

Style: Indicates the type of arrow to be displayed. The choices are Open Ended, Block, and Crossed. Block will display an arrow with a closed end. Open Ended will be a block arrow with an open end. Crossed indicates that a cross will be placed in the body of the arrow. The default value is Open Ended. Width: Indicates the distance between the lines that construct the body of the arrow. The default value is 20 pt.  

Begin cut: Indicates the distance from the beginning of a line that the stroke will start to be displayed. The beginning of a line is determined by the direction in which the line was digitized. The distance is applied along the line. The default value is 1 pt. End cut: Indicates the distance from the end of a line that the stroke will start to be displayed. The ending of a line is determined by the direction in which the line was digitized. The distance is applied along the line. The default value is 1 pt. Invert: Indicates the effect should be applied in the opposite manner. This will display the stroke symbol only at the ends of the line and leave the rest of the line unsymbolized. The default value is unchecked. 


Pattern: Indicates the distance for each dash and gap. There can be multiple dash and gap values to form a complex pattern. A dash is the symbolized part of the stroke, and a gap is the unsymbolized part of the stroke. When the length of the line does not support the display of the entire pattern, the pattern will be compressed to fit. Using an odd number of values will cause the pattern to double itself in overall length. The second half of the pattern will be the reverse of the first half. Using a value of 0 (zero) is acceptable. These options allow more complex dash patterns to be created. The default values are 10 pt and 10 pt. Endings: The position of the dash along a line. The choices are No constraint, With half pattern, With full pattern, With half gap, With full gap, and Custom. Custom will fit the pattern to the length of the feature by adjusting the gaps slightly. No constraint will not adjust the gaps at all, meaning that the pattern is unlikely to exactly fit the length of the feature. The default is With half pattern. Position: Indicates where the pattern should begin relative to the starting point of the geometry. It shifts the entire pattern along the line the specified distance. Negative numbers indicate a shift to the left, positive numbers a shift to the right. This property has an effect only if Endings is set to No constraint or Custom. When constructing a representation rule, this property will be dynamically derived from the Step value and will dynamically update during rule construction or modification when the Endings property is updated. Offset at end: Indicates where the pattern should end relative to the ending point of the geometry. Negative numbers indicate a shift to the left, positive numbers a shift to the right. This property has an effect only if Endings is set to Custom. When constructing a representation rule, this parameter will be dynamically derived from the Step value and will dynamically update during rule construction or modification when the Endings property is updated. 

Length: The length of the segment that forms the jog in the line. Position: Location of the center of the jog, as a percentage measured from the start of the input geometry. Angle: The angle of the jog in the line, measured in degrees.

Offset: The distance of the stroke perpendicular to the line's geometry. The default value is 1 pt. Method: Indicates the way the strokes will display at corners. The choices are Mitered, Bevelled, Rounded, and Square. Mitered will match the exact shape around a corner of the line. Bevelled will follow the shortest straight path across a corner of the line. Rounded will follow a path of equal distance around a corner of the line. Square will follow a straight path across the corner of a line. The default value is Square. Option: Indicates the way strokes will handle complex geometries. The choices are Fast and Accurate. Fast will ignore complex geometries and apply a best fit to the stroke symbol. Accurate will accommodate complex geometries and apply a true fit to the stroke symbol. The default value is Fast. Count: The number of times the stroke should be offset. The default value is 1.

Tolerance: Indicates the distance along a polygon outline to remove vertices from the stroke symbol. The default value is 10 pt. A value of less than 10 will maintain more of the original shape of the stroke. A value of greater than 10 will maintain less of the original shape of the stroke. 


Flat tolerance: Indicates the distance along a line to include segments for a dynamic Bézier curve. The default value is 1 pt. A value greater than 1 will consider fewer segments for a dynamic Bézier curve of the polygon outline. 


Period: Indicates the distance along a line to display the curve for the stroke symbol. The default value is 3 pt. Width: Indicates the distance perpendicular to a line to display the curve for the stroke symbol. The default value is 2 pt. Style: Indicates the shape of the curve to be displayed. The choices are Sinus, Square, Triangle, and Random. Sinus will display a sinusoidal curve or half moon shape. Square will display a three sided rectangular shaped curve. Triangle will display a two sided triangular shaped curve. Random will display a sine curve with random variation in the period and width of the curve. The default value is Sinus. Seed: Indicates the starting value for generating a random number. This random number is used by the Style type Random to determine which size a marker will receive. The default value is 1. 

Polygon 

Size: The distance from the edge of the stroke. The default value is 1 pt. 


Method: Indicates the way in which the polygon geometry will be generated around the stroke. The choices are Close path, Convex hull, and Rectangle box.

Invert: Indicates the effect should be applied in the opposite manner. This will display the stroke symbol only at the closing point of a polygon with the rest of the polygon outline unsymbolized. The default value is unchecked. 


Pattern: Indicates the distance for each dash and gap. There can be multiple dash and gap values to form a complex pattern. A dash is the symbolized part of the stroke, and a gap is the unsymbolized part of the stroke. When the length of the line does not support the display of the entire pattern, the pattern will be compressed to fit. Using an odd number of values will cause the pattern to double itself in overall length. The second half of the pattern will be the reverse of the first half. Using a value of 0 (zero) is acceptable. These options allow more complex dash patterns to be created. The default values are 10 pt and 10 pt. Endings: The position of the dash along a polygon outline. The choices are No constraint, With half pattern, With full pattern, With half gap, With full gap, and Custom. Custom will fit the pattern to the length of the feature by adjusting the gaps slightly.

Negative numbers indicate a shift to the left, positive numbers a shift to the right. This property has an effect only if Endings is set to No constraint or Custom.
