Input geometry	Output geometry	Geometric effect	Description	Example
Point	Line	Radial from point	Creates a dynamic line of a specified length and angle originating from a point feature
	Polygon	Buffer	Creates a dynamic polygon with a specified diameter around a point feature
	Polygon	Regular polygon	Creates a dynamic polygon around a point feature with a specified number of edges. All edges are equal in length and all angles are equal.
Line	Line	Add control points	Dynamically adds representation control points to a line feature to dictate the placement of marker placement styles or geometric effects that use a template
	Line	Cut	Creates a dynamic line that is shorter on one or both ends than a line feature
	Line	Dashes	Creates dynamic multipart line geometry from a line feature based on a template
	Line	Move	Creates a dynamic line offset a specified distance in x and y ; often used to mimic a drop shadow
	Line	Offset	Creates a dynamic line offset at a specified distance perpendicularly from a line feature
	Line	Reverse	Flips the dynamic output of another geometric effect
	Line	Rotate	Creates a dynamic line rotated a specified angle from a line feature

Parameter Definitions

Input Geometry	Output Geometry	Geometric Effect	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 counter-clockwise 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.
	Polygon		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. Specifiying 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).
	Line		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.
	Line		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 un-symbolized 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) will is acceptable. These options allow for more complex dash patterns to be created. The default values are 10pt and 10pt. Endings: Indicates how the stroke symbol will be displayed at the ends of lines. The choices are No constraint, With half pattern, With full pattern, With half gap and With half gap. No constraint will draw the full pattern at the beginning of the line and as much of the pattern as remains at the end of the line. With half pattern will display half of the dash value at both ends of the line. With full pattern will display the full dash value at both ends of the line. With half gap will display half of the gap value at both ends of the line. With full gap will display the full gap value at both ends of the line. The first dash value and first gap value are used by default. The default value is With half pattern.
	Line		X Offset: The distance to move the symbol along the X-axis from the feature geometry. The default value is 1 pt. Y Offset: The distance to move the symbol along the Y-axis from the feature geometry. The default value is -1 pt.
	Line		Offset: The distance of the stroke perpendicular to the lines 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.

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.
	Line		Reverse: Indicates whether or not the dynamic output of a previous geometric effect will be flipped or not. The default value is checked.
