Elliptic Arc
Create an elliptic arc to be used either as a building block for constructing geometry or as a wire.
Method 1: Centre point, radii, start angle, end angle
|
Centre point (C) | The centre of the ellipse on which the arc lies. |
Radius (RU) | The radius (half of the axis length) in the U axis direction of the ellipse on which the arc lies. | |
Radius (RV) | The radius (half of the axis length) in the V axis direction of the ellipse on which the arc lies. | |
Start angle (A0) | The angle, from the positive U axis direction where the arc begins. | |
End angle (A1) | The angle, from the positive U axis direction where the arc ends |
Method 2: V major axis direction - Aperture centre, depth, aperture radius, eccentricity
|
Aperture centre (C) | The centre of the aperture formed by the elliptical arc section. |
Depth (D) |
The distance from the aperture centre point to the apex of the elliptical arc section. |
|
Aperture radius (R) | The radius of the aperture of the elliptic arc. | |
Eccentricity | The eccentricity of the ellipse on which the elliptical arc section lies.
Note: The eccentricity must be less than 1 to specify a valid
ellipse.

Conditions for creating a valid elliptic arc:
