Parent object for Geometric Dimensionsing and Toleration Frames, attaching them to the pixel location on the drawing.
|Bounding polygon of the GDT annotation as tuple of x, y coordinates in the pixel coordinate system of the sectional.
NOTE: simple GDTs are represented by a simple rectangle.To support more complex GDTs (e.g., with a Sectional Plane Indicator, we define a polygon)
NOTE: the polygon starts at the top left and is oriented clock-wise.
|[(0.1,0.5), (0.2,0.5), (0.2,0.45), (0.1,0.45)]|
|Details on the GDT Frame||see W24GDTFrame|
|Optional size dimension, typically annotated above the feature control frame.
⌀12.0 + /- 0.1
The GD&Ts also decribe Sectional Plane Indicators (e.g., ⟨[∥| A]), Orientational Plane Indicators (e.g., ⟨[∥| A]⟩), Directional Feature Indicators (e.g., ←[∥| A]) and Collection Plane Indicators (e.g., ◯[∥| B]). These attributes are currently not available.
