Trapeze (class)

Method code available at https://github.com/Eomys/pyleecan/tree/master/pyleecan/Methods/Geometry/Trapeze

class Trapeze(height=1, W2=1, W1=1, point_ref=0, label='', init_dict=None, init_str=None)[source]

Bases: pyleecan.Classes.Surface.Surface

Trapeze defined by the center of symmetry(point_ref), the label, the polar angle, the height and the big and small weight

VERSION = 1

Parameters:self (Trapeze) – a Trapeze object
Returns:point_list – list of complex coordinate of the points
Return type:list
get_lines()

Returns the Lines that delimit the Trapeze

Parameters:self (Trapeze) – a Trapeze object

get_patches(color='w', edgecolor='k', is_edge_only=False, linestyle=None)

Returns the Trapeze Patch to be display in matplotlib

Parameters:
  • self (Trapeze) – a Trapeze object
  • color – the color of the patch (Default value = PATCH_COLOR)
  • edgecolor – the color of the patch’s edges (Default value = PATCH_EDGE)
  • is_edge_only (bool) – To set the transparancy of the face color to 0 and 1 for the edge color
  • linestyle (str) – Line style of the edge {‘-‘, ‘–’, ‘-.’, ‘:’, ‘’, (offset, on-off-seq), …}
Returns:

patch_list – List of patches corresponding to the surface

Return type:

list of matplotlib.patches.Polygon

rotate(angle)

Returns:

Return type:

None

comp_point_ref(is_set=False)

Compute the point ref of the Surface

Parameters:
  • self (Trapeze) – A Trapeze object
