class Arc2(begin=0, center=0, angle=1.57079633, label='', init_dict=None)[source]

Bases: pyleecan.Classes.Arc.Arc

An arc between two points (defined by the begin point and a center and angle)

VERSION = 1
check()

assert that the arc is correct (begin != center)

Parameters:

self (Arc2) – An Arc2 object
Returns:
Return type:

None
Raises:
  • PointArc2Error – The beginning point and the ending point of an Arc2 can’t be the same
  • AngleArc2Error – An Arc2 can’t have a null opening angle
comp_length()

Compute the length of the arc

Parameters:self (Arc2) – An Arc2 object
Returns:length – length of the arc
Return type:float
comp_radius()

Compute the radius of the arc

Parameters:self (Arc2) – An Arc2 object
Returns:radius – radius of the arc
Return type:float
discretize(nb_point=99)

Return the discretize version of the Arc. Begin and end are always returned

Parameters:
  • self (Arc2) – An Arc2 object
  • nb_point (int) – Number of points to add to discretize the arc (Default value = ARC_NPOINT_D)
Returns:

list_point – list of complex coordinate of the points
Return type:

list
Raises:

NbPointArc2DError – nb_point must be an integer >=0
get_angle(is_deg=False)

Return the angle of the arc

Parameters:
