group a3d_markupgdt

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 A3DMDFeatureControlFrameData).
Tolerances Sizes (ref 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.
