involuteCircular	Function in std::sketch	Extend the current sketch with a new involute circular curve.	manual

Extend the current sketch with a new involute circular curve.

involuteCircular(
  @sketch: Sketch,
  angle: number(Angle),
  startRadius?: number(Length),
  endRadius?: number(Length),
  startDiameter?: number(Length),
  endDiameter?: number(Length),
  reverse?: bool,
  tag?: TagDecl,
): Sketch

Arguments

Name	Type	Description	Required
sketch	Sketch	Which sketch should this path be added to?	Yes
angle	number(Angle)	The angle to rotate the involute by. A value of zero will produce a curve with a tangent along the x-axis at the start point of the curve.	Yes
startRadius	number(Length)	The involute is described between two circles, startRadius is the radius of the inner circle. Either startRadius or startDiameter must be given (but not both).	No
endRadius	number(Length)	The involute is described between two circles, endRadius is the radius of the outer circle. Either endRadius or endDiameter must be given (but not both).	No
startDiameter	number(Length)	The involute is described between two circles, startDiameter describes the inner circle. Either startRadius or startDiameter must be given (but not both).	No
endDiameter	number(Length)	The involute is described between two circles, endDiameter describes the outer circle. Either endRadius or endDiameter must be given (but not both).	No
reverse	bool	If reverse is true, the segment will start from the end of the involute, otherwise it will start from that start.	No
tag	TagDecl	Create a new tag which refers to this line.	No

Returns

Sketch - A sketch is a collection of paths.

Examples

a = 10
b = 14
startSketchOn(XZ)
  |> startProfile(at = [0, 0])
  |> involuteCircular(startRadius = a, endRadius = b, angle = 60deg)
  |> involuteCircular(
       startRadius = a,
       endRadius = b,
       angle = 60deg,
       reverse = true,
     )
