ARC¶
Type: Basic DXF R12 entity.
Draws circular arcs — arcs cut from circles, not from ellipses, parabolas, or some other complicated curve, the arc goes from start angle to end angle.
-
DXFEngine.
arc
(radius=1.0, center=(0., 0.), startangle=0., endangle=360., **kwargs)¶ Parameters: - radius (float) – arc radius
- center – center point (xy- or xyz-tuple), z-axis is 0 by default
- startangle (float) – start angle in degree
- endangle (float) – end angle in degree
Common Keyword Arguments for all Basic DXF R12 Entities¶
keyword | description |
---|---|
layer | Layer name as string |
linetype | Linetype name as string, if not defined = BYLAYER |
color | as integer in range [1..255], 0 = BYBLOCK, 256 = BYLAYER |
thickness | Thickness as float |
paper_space | 0 = entity is in model_space, 1 = entity is in paper_space |
extrusion_direction | 3D Point as tuple(x, y, z) if extrusion direction is not parallel to the World Z axis |
Attribs of DXF entities can be changed by the index operator:
from dxfwrite import DXFEngine as dxf
drawing = dxf.drawing('drawing.dxf')
arc = dxf.arc(2.0, (1.0, 1.0), 30, 90)
arc['layer'] = 'points'
arc['color'] = 7
arc['center'] = (2, 3, 7) # int or float
arc['radius'] = 3.5
drawing.add(arc)
drawing.save()
