Paraboloid Primitive dialog box (SST)

Common options

Option	Description
Element Type	Lists the supported 2D element types.
Destination Collector
Mesh Collector	Lets you select an existing collector. Click New Collector to use the Mesh Collector dialog box to create additional mesh collectors. See Mesh collectors for more information.
Definition
By	Controls the definition method:Parameters: Lets you define the paraboloid by assigning values to parameters in relation to a coordinate system you specify.Points: Lets you define the paraboloid by locating points in space in terms of 3D coordinates.
Mesh Density
Along Circumference	Defines the number of elements along the circumferential surface of the paraboloid. This surface is defined by the specified Start Angle and End Angle. At the end of each traversal between the circumferential limits, the element sequence continues at the Start Angle in the next layer up.
Along Height	Defines the number of elements along the vertical height of the paraboloid. The number of elements defines the number of layers in the mesh.Note: No mesh is created on the flat circular surface.
Top side faces inward	Select the check box to reverse the direction of the surface normals of the 2D elements so that they point inward.

Paraboloid primitive defined by parameters

Option	Description
Definition
Coordinate System	Lets you create or select a coordinate system. The software uses the origin of the coordinate system as the origin of the paraboloid primitive.See CSYS dialog box for more information.
Height	Defines the total height of the paraboloid as a distance from the origin along the Z-axis. The vertex of the paraboloid is at the origin.
Height to truncate at	Defines a distance from the origin along the Z-axis to truncate the paraboloid. The paraboloid section from the vertex to this height is cut away.
Focal Length	Defines the location of the focal point as a distance from the origin along the Z-axis.
Start Angle / End Angle	Defines a circumferential segment of the paraboloid body measured from the X-axis. The segment of the paraboloid from the Start Angle to the End Angle defines the circumferential limits of the primitive.Note: The values for Start Angle must always be less than the value for End Angle.

Paraboloid primitive defined by points

Option	Description
Definition
By	Select Points to use this definition method.
Origin	Lets you select or create a point to define as the origin for the paraboloid.Click Point Constructor to use the Point dialog box to create a new point. See Point dialog box for more information.
Z axis	Lets you select or create a point to define the Z-axis. This controls the height of the paraboloid in relation to the Origin.Note: The axis of the paraboloid is always perpendicular to the X-Y plane.
Radius extent – start position	Lets you select or create a point to define the starting location in the circumferential direction for the segment of the paraboloid surface included in the primitive. It also defines the radius of the circular face of the paraboloid.Note: For clarity, select or create the point on the circumference of the circular surface.
Truncate along Circumference	Lets you define a circumferential limit (less than 360°) for the paraboloid primitive.
Radius extent – end position	Appears only if Truncate along Circumference is selected.Lets you select or create a point to define the truncating limit in the circumferential direction for the segment of the paraboloid surface included in the primitive.
Truncate Bottom	Lets you define a truncating height in the vertical direction for the paraboloid primitive.
Height to truncate at	Appears only if Truncate Bottom is selected.Lets you select or create a point to define a truncating plane perpendicular to the axis of the paraboloid offset from the Origin.
