Parameters

Index

Index of the leader

PointCount

Number of (x,y,z) points returned in the array

Return Value

• in-process, unmanaged C++: Pointer to array of doubles (see Remarks)

A GTol can have a straight leader (1 segment) or a bent leader (2 segments), or it might have a perpendicular leader, which can have either 2 or 3 segments, depending on the situation. The returned array contains the point information to define the leader. It contains the x,y,z coordinates for each vertex in the leader. It can contain up to 12 doubles (4 sets of x,y,z values).

Because the return value is passed into this method, it should be dimensioned to 12 before this method is called to allow for the maximum number of items that can be returned (4 segments). Upon return from the API, the PointCount argument contains the actual number of points stored in the array. Multiply this number by 3 to determine the number of array items actually used.
