W24GDT

Parent object for Geometric Dimensionsing and Toleration Frames, attaching them to the pixel location on the drawing.

PAYLOAD DICT EXAMPLE
bounding_polygon
(List[Tuple[float, float]])
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)]
frame
(W24GDTFrame)
Details on the GDT Frame see W24GDTFrame
measure_label
(Optional[W24MeasureLabel])
Optional size dimension, typically annotated above the feature control frame.

Example:
⌀12.0 + /- 0.1
[⊥|⌀0.1Ⓜ| A]
See W24Measure

Note

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.
