CylinderMixin

Synopsis

This design is used as a mixin in other designs to define a cylindrical system, dimensions and points . However, it does not have any geometry of its own.

Mixins

BaseModifier

Canonicals

Name	Type	Description
height	number	Height of the Cylinder along the Z axis from the bottomPoint to the topPoint
radius	number	Radius of the Cylinder in the XY plane measured at the bottomPoint

Parameters

Name	Type	Description
bottomPoint	point	Point at the center of the bottom face of the Cylinder.
topPoint	point	Point at the center of the top face of the Cylinder.
diameter	number	Diameter of the Cylinder in the XY plane measured at the bottomPoint.
axis	vector	Vector from the bottomPoint towards the topPoint. Used when only one of the two defining points , topPoint or bottomPoint, is specified.
closed?	boolean	When true , specifies that the ends of the cylinder are closed.
startAngle	number	Specifies the beginning angle for a partial cylinder.
endAngle	number	Specifies the ending angle for a partial cylinder.

Group Rules

<diameter_only (diameter)> Providing a diameter will satisfy the required radius.

<_bottomPoint (bottomPoint)> Supplying bottomPoint will locate the Cylinder relative to the center of the bottom face. The height and radius are also required.

<_topPoint (topPoint)> Supplying topPoint will locate the Cylinder relative to the center of the top face. The height and radius are also required.

<bottomPoint_axis (bottomPoint axis)> Supplying bottomPoint and axis will locate the Cylinder relative to the center of the bottom face and change the Cylinder's axis accordingly. The height and radius are also required.

<topPoint_axis (topPoint axis)> Specifying topPoint and axis will locate the Cylinder relative to the center of the top face and change the Cylinder's axis accordingly. The height and radius are also required.

<topPoint_bottomPoint (topPoint bottomPoint)> Supplying topPoint and bottomPoint will locate the Cylinder relative to both the top and bottom face centers. These two points will also determine the Cylinder's height and axis, but the radius is still required.
