IMcProfileEdgesTicMarkOrientation Property

Property Value

Type: Double

The TicMarkOrientation is given in degrees. It specifies the orientation of the tic marks drawn at "edges" for the EdgeTicMarksAsMcLines property. Tic marks are oriented at the specified angle, counter clockwise from the angle of the ancestor line segment where the edge is placed. The TicMarkOrientation is 90 degrees by default, and it may be given any value from -360 to 360 degrees. Values of zero or 180 usually make no sense, but they are allowed. Typical values will be + or - 60, 90 and 120 degrees. TicMarkOrientation is most important when two or more McProfileEdges are instantiated as children of the same McLineProfiles. You would do this if you were, for example, looking for both rising and falling edges along some McLines. To avoid the marks for leading and trailing edges looking identical, you might set EdgeTicMarksAsMcLines as 90 for one and -90 for the other. Or to put both marks on the same side of the line you might set EdgeTicMarksAsMcLines as 120 for the rising edges and 60 for the falling edges (this would produce a backward stroke on the rising edge and a forward stroke on the falling edge). On assignment, the built-in EdgeTicMarksAsMcLines (the default one accessed as the EdgeTicMarksAsMcLines property) is automatically updated with the new tic mark orientation, but sub-set McLines created by passing a selector to EdgeTicMarksAsMcLines are not automatically updated.
