class Arc1(begin=0, end=0, radius=0, label='', init_dict=None)[source]

Bases: pyleecan.Classes.Line.Line

An arc between two points (defined by a radius)

VERSION = 1
check()

assert that the arc is correct (begin != end; radius !=0)

Parameters:

self (Arc1) – An Arc1 object

Returns:

Return type:

None

Raises:
  • PointArc1Error – The beginning point and the ending point of an Arc1 can’t be the same
  • RadiusArc1Error – An Arc1 can’t have a null radius
comp_length()

Compute the length of the arc

Parameters:self (Arc1) – An Arc1 object
Returns:length – length 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 (Arc1) – The Arc1 object to discretize
  • nb_point – 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:

NbPointArc1DError – nb_point must be an integer >=0

get_begin()

Parameters:self (Arc1) – An Arc1 object
Returns:begin – Complex coordinates of the begin point of the Arc1
Return type:complex
get_center()

Return the center of the arc

Parameters:self (Arc1) – An Arc1 object

Parameters:self (Arc1) – An Arc1 object
Returns:Zmid – Complex coordinates of the middle of the Arc1
Return type:complex
rotate(angle)

Rotation of the Arc1 of <angle> rad with 0 as the center

Parameters:
