|GPTEX2 (point1, point2, index)|
Use GPTEX2 to insert a Test Extent 2 structure element into the open structure following the element pointer or to replace the element pointed at by the element pointer with a Test Extent 2 structure element depending on the current edit mode.
The Test Extent 2 structure element is a short hand form of the Test Extent 3 structure element. During traversal the two endpoints of this element are expanded to 3D by supplying zero z values and then are treated the same as Test Extent 3. (See the Test Extent 3 [ GPTEX3] subroutine [page GPTEX3 - Test Extent 3) for further details.)
GPTEX2 is identified as GSE 1007.
Not all GSEs are supported on all workstations. Use the Inquire List of Generalized Structure Elements (GPQGSE) inquiry subroutine to determine the GSEs supported by an open workstation. See also the workstation descriptors in The graPHIGS Programming Interface: Technical Reference
