circlefrom1Line2Points()

def draftgeoutils.circles.circlefrom1Line2Points	(		edge,
			p1,
			p2
	)

Return a list of circles created from an edge and two points. It calculates up to 2 possible centers.

circlefrom2Lines1Point()

def draftgeoutils.circles.circlefrom2Lines1Point	(		edge1,
			edge2,
			point
	)

Return a list of circles from two edges and one point.

circleFrom2LinesRadius()

def draftgeoutils.circles.circleFrom2LinesRadius	(		edge1,
			edge2,
			radius
	)

Retun a list of circles from two edges and one radius. It calculates 4 centers.

circleFrom2PointsRadius()

def draftgeoutils.circles.circleFrom2PointsRadius	(		p1,
			p2,
			radius
	)

Return a list of circles from two points, and one radius. The two points must not be equal. It calculates up to 2 possible centers.

circleFrom3LineTangents()

def draftgeoutils.circles.circleFrom3LineTangents	(		edge1,
			edge2,
			edge3
	)

Return a list of circles from three edges. It calculates up to 6 possible centers.

circleFromPointLineRadius()

def draftgeoutils.circles.circleFromPointLineRadius	(		point,
			edge,
			radius
	)

Return a list of circles from one point, one edge, and one radius. It calculates up to 2 possible centers.

findClosestCircle()

def draftgeoutils.circles.findClosestCircle	(		point,
			circles
	)

Return the circle with closest center to a given point.

findHomotheticCenterOfCircles()

def draftgeoutils.circles.findHomotheticCenterOfCircles	(		circle1,
			circle2
	)

Calculate the homothetic centers from two circles. Return None if the objects are not circles, or if they are concentric. http://en.wikipedia.org/wiki/Homothetic_center http://mathworld.wolfram.com/HomotheticCenter.html

findRadicalAxis()

def draftgeoutils.circles.findRadicalAxis	(		circle1,
			circle2
	)

Calculate the radical axis of two circles. On the radical axis (also called power line) of two circles any tangents drawn from a point on the axis to both circles have the same length. http://en.wikipedia.org/wiki/Radical_axis http://mathworld.wolfram.com/RadicalLine.html See Also -------- findRadicalCenter

findRadicalCenter()

def draftgeoutils.circles.findRadicalCenter	(		circle1,
			circle2,
			circle3
	)

Calculate the radical center of three circles. It is also called the power center. It is the intersection point of the three radical axes of the pairs of circles. http://en.wikipedia.org/wiki/Power_center_(geometry) http://mathworld.wolfram.com/RadicalCenter.html See Also -------- findRadicalAxis

getCircleFromSpline()

def draftgeoutils.circles.getCircleFromSpline

(

edge

)

Return a circle-based edge from a bspline-based edge. Return None if the edge is not a BSplineCurve.
