involuteCircular	Extend the current sketch with a new involute circular curve.	manual

Extend the current sketch with a new involute circular curve.

involuteCircular(
  sketch: Sketch,
  startRadius: number,
  endRadius: number,
  angle: number,
  reverse?: bool,
  tag?: TagDeclarator,
): Sketch

Arguments

Name	Type	Description	Required
sketch	Sketch	Which sketch should this path be added to?	Yes
startRadius	number	The involute is described between two circles, start_radius is the radius of the inner circle.	Yes
endRadius	number	The involute is described between two circles, end_radius is the radius of the outer circle.	Yes
angle	number	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
reverse	bool	If reverse is true, the segment will start from the end of the involute, otherwise it will start from that start. Defaults to false.	No
tag	TagDeclarator	Create a new tag which refers to this line	No

Returns

Sketch

Examples

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