cqmore.polygon

Provide functions for creating simple polygons.

Functions

Signature Description
taiwan(h[,distance]) Create a convex hull through the provided points.
regularPolygon(nSides,radius[,thetaStart,thetaEnd]) Create a regular polygon.
star([outerRadius,innerRadius,n]) Create a star.
hull2D(points) Create a convex hull through the provided points.

taiwan

Create a Taiwan profile.

Parameters

  • h : The height of Taiwan.
  • distance = 0 : used for simplifying the shape. If the distance between a point and its previous points is not greater than distance, the point will be kept.

Examples

from cqmore import Workplane
from cqmore.polygon import taiwan

taiwan = (Workplane()
            .makePolygon(taiwan(20))
            .extrude(1)
        )

taiwan

regularPolygon

Create a regular polygon.

Parameters

  • nSides: number of sides.
  • radius: the size of the polygon.
  • thetaStart = 0: start angle for the first segment.
  • thetaEnd = 360: end angle for the last segment.

Examples

from cqmore import Workplane
from cqmore.polygon import regularPolygon

polygon = (Workplane()
                .makePolygon(regularPolygon(nSides = 6, radius = 10))
                .extrude(1)
            )

regularPolygon

from cqmore import Workplane
from cqmore.polygon import regularPolygon

polygon = (Workplane()
                .makePolygon(
                    regularPolygon(
                        nSides = 6, 
                        radius = 10, 
                        thetaStart = 45, 
                        thetaEnd = 270
                    )
                )
                .extrude(1)
            )

regularPolygon

star

Create a star. Default to a pentagram.

Parameters

  • outerRadius = 1: the outer radius of the star.
  • innerRadius = 0.381966: the inner radius of the star.
  • n = 5: the burst number.

Examples

from cqmore import Workplane
from cqmore.polygon import star

polygon = (Workplane()
                .makePolygon(
                    star(outerRadius = 10, innerRadius = 5, n = 8)
                )
                .extrude(1)
            )

star

hull2D

Create a convex hull through the provided points.

Parameters

  • points: a list of x, y points.

Examples

from random import random
from cqmore import Workplane
from cqmore.polygon import hull2D

points = [(random(), random()) for i in range(20)]
convex_hull = Workplane().makePolygon(hull2D(points))
