Geometrical dimensioning tolerance
##################################


   4.0


A markup GDT is composed of appended texts and an array of tolerances. Tolerances that can be of two types :


- features control frame tolerance (ref :c:struct:`~A3DMDFeatureControlFrameData`\ ).
- Tolerances Sizes (ref :c:struct:`~A3DMDToleranceSizeData`\ ). which allow to define all the dimension of an element. For example for a hole we can have a tolerance size that will contain the value of the diameter, the value of the depth and the angle defining the V shape at the bottom of the hole.

**Returns**


   ``A3D_SUCCESS``\ on success, or an error code on failure
