double IGetLeaderInfo(

Parameters

PointCount

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

Return Value

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

See In-process Methods for details about this type of method.

There can be 0, 1 or 2 lines with the leader line. If the GTol is not attached, then there are 0 lines. Otherwise, the GTol can have a straight leaderline (1 line) or a bent leaderline (2 lines). The caller must infer the number of leader lines based on IGtol::IsAttached and IGtol::HasExtraLeader.

• IGtol::IsAttached() == false implies no leaderline; therefore, there are no leaderline points (PointCount=0).

• IGtol::HasExtraLeader() == false means that this is a straight leaderline; therefore, there is 1 line (PointCount=2).

• IGtol::HasExtraLeader() == True means that this is a bent leaderline; therefore, there are 2 lines (PointCount=3).

The format of return information is the following array of doubles:

retval[0] = X-coordinate of first leader point

retval[1] = Y-coordinate of first leader point

retval[2] = Z-coordinate of first leader point

retval[3] = X-coordinate of second leader point

retval[4] = Y-coordinate of second leader point

retval[5] = Z-coordinate of second leader point

retval[6] = X-coordinate of third leader point

retval[7] = Y-coordinate of third leader point

retval[8] = Z-coordinate of third leader point

Use IGtol::GetLeaderCount to see how many leaders are on the IGTol object.
