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

Bases: pyleecan.Classes.Arc.Arc

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
