QRouteLead

class QRouteLead(*args, **kwargs)

A simple class to define a an array of points with some properties, defines 2D positions and some of the 2D directions (XY plane).

All values stored as np.ndarray of parsed floats.

QRouteLead is a simple sequence of points.

Used to accurately control one of the QRoute termination points Before that, it adds the variables that are needed to support routing.

pts

Sequence of points. Defaults to None.

Type:

numpy Nx2

direction

Normal from the last point of the array. Defaults to None.

Type:

numpy 2x1

Attributes

length

Sum of all segments length, including the head.

Returns:

Full point_array length

Return type:

length (float)

Methods

get_tip() → QRoutePoint

Access the last element in the QRouteLead.

Returns:

Last point in the QRouteLead The values are numpy arrays with two float points each.

Return type:

QRoutePoint

go_angle(length: float, angle: float)

Straight line at any angle w.r.t lead tip direction.

Parameters:

• length (float) – How much to move by

• angle (float) – rotation angle w.r.t lead tip direction

go_left(length: float)

Straight line 90deg counter-clock-wise direction w.r.t. lead tip direction.

Parameters:

length (float) – How much to move by

go_left45(length: float)

Straight line at 45 angle counter-clockwise w.r.t lead tip direction.

Parameters:

length (float) – How much to move by

go_right(length: float)

Straight line 90deg clock-wise direction w.r.t. lead tip direction.

Parameters:

length (float) – How much to move by

go_right45(length: float)

Straight line at 45 angle clockwise w.r.t lead tip direction.

Parameters:

length (float) – How much to move by

go_straight(length: float)

Add a point ot ‘length’ distance in the same direction.

Parameters:

length (float) – How much to move by

seed_from_pin(pin: Dict) → QRoutePoint

Initialize the QRouteLead by giving it a starting point and a direction.

Parameters:

pin – object describing the “reference_pin” (not cpw_pin) this is attached to. this is currently (8/4/2020) a dictionary

Returns:

Last point (for now the single point) in the QRouteLead The values are numpy arrays with two float points each.

Return type:

QRoutePoint
