Polylines
A Polyline is a set of connected segments and is defined by a list of points. It may be set to closed to automatically set the last point to the first point.
# Created in DeclaraCAD
from math import pi
from declaracad.occ.api import *
enamldef Assembly(Part):
Polyline:
color = 'red'
points = [(0, 0), (4, 0), (4, 2), (2, 4), (0, 4)]
Polyline:
color = 'blue'
points = [(0, 0), (1, 2), (3, 2)]
closed = True
# For reference
Line: xaxis:
color = 'black'
direction = (1, 0)
Line: yaxis:
color = 'black'
direction = (0, 1)
The points can be accessed like a normal python list which is useful for chaining multiple edges together into a wire.
Polygons
DeclaraCAD also includes a Polygon which is just a closed Polyline with count points calculated for you that revolves around a inscribed or circumscribed radius.
This is best shown by example.
# Created in DeclaraCAD
from math import pi
from declaracad.occ.api import *
enamldef Assembly(Part):
Circle: c1:
color = 'lime'
radius = 3
Polygon: p1:
color = 'red'
radius = c1.radius
count = 6
Polygon: p2:
color = 'blue'
radius = c1.radius
count = 6
inscribed = True
# For reference
Line: xaxis:
color = 'black'
direction = (1, 0)
Line: yaxis:
color = 'black'
direction = (0, 1)
This shows a circle and two polygons showing the difference between circumscribed (the default) and inscribed.
