Overview
The geometric tolerance objects enable you to access internal data structure of geometric tolerances (gtol). The object also references and gets attachment details for gtols.
From 4.0 F000 onward, the object Gtoldata has been deprecated. All the ProGtolData* functions have also been deprecated. Use the new ProGtol* functions instead. The new functions are defined in the header files ProGtol.h and ProGtolAttach.h.
Note:
 
Geometric tolerance functions deprecated in 4.0 F000 must not be used with the new geometric tolerance functions available from 4.0 F000 in a application. If the functions are used together in an application, the results may be unpredictable.
ProGtol
Geometric tolerances in a model are referenced by the data handle, ProGtol. This handle is identical to ProModelitem, in which the type field is set to PRO_GTOL. You can use ProSelect() with the option gtol to select a gtol, after which you can extract the ProGtol handle using ProSelectionModelitemGet().
ProGtolAttach
This is an opaque handle object that references an internal data structure which provides complete attachment details for a gtol. The structure contains attachment information such as, type of placement, annotation plane, location and references and so on for a gtol.
