weldx.geometry.ArcSegment#

class weldx.geometry.ArcSegment(points, arc_winding_ccw=True)#

Arc segment.

Construct arc segment.

Parameters
  • points (Quantity) – 2x3 matrix of points. The first column is the starting point, the second column the end point and the last the center point.

  • arc_winding_ccw (bool) – Specifies if the arcs winding order is counter-clockwise

Return type

ArcSegment

Examples

Create a ̧̧`LineSegment` starting at x=3,``y=4`` and ending at x=1, y=6 with the center point x=1,``y=4``

>>> from weldx import Q_, ArcSegment
>>> point_data = Q_([[3, 1, 1], [4, 6, 4]], "mm")
>>> ArcSegment(point_data)
<ArcSegment>
Line:
    [3.00 4.00] mm -> [1.00 6.00] mm
Center:
    [1 4] mm
Radius:
    2.00 mm
Length:
    3.14 mm
Winding order:
    counter-clock-wise
