Disc 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 disc by assigning values to parameters in relation to a coordinate system you specify.Points: Lets you define the disc by locating points in space in terms of 3D coordinates.
Mesh Density
Along Circumference	Defines the number of elements along the circumferential direction of the disc located by the 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 Radius	Defines the number of elements along the radial direction of the disc. The number of elements defines the number of layers in the mesh.
Top side points towards – Z	Select the check box to reverse the direction of the surface normals of the 2D elements so that they point towards the – Z direction.

Disc 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 primitive.See CSYS dialog box for more information.
Outer Radius	Defines the outer radius as a distance from the origin.Note: The disc is always parallel to the X-Y plane.
Inner Radius	Defines the inner radius as a distance from the origin.Note: Use this radius only to define an annular region of a disc.
Start Angle / End Angle	Defines a circumferential segment of the disc primitive measured from the X-axis in counter clockwise direction (as measured from Z-axis). The segment of the disc from the Start Angle to the End Angle defines the circumferential limits of the primitive.Note: The value for Start Angle must always be less than the value for End Angle.
Offset in Z	Defines the offset value for the disc section along the Z-axis as a distance from the origin. The disc is always parallel to the X-Y plane.

Parameter	Definition
	Outer Radius
	Inner Radius
	Start Angle
	End Angle
	Offset in Z (not pictured)

Disc primitive defined by points

Option	Description
Definition
Center	Lets you select or create a point to define as the center of the disc.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 axis of the disc in relation to the Center.Note: The axis of the disc is always perpendicular to the X-Y plane and the disc is always at the X-Y plane.
Outer Radius – start position	Lets you select or create a point to define the outer radius of the disc. It also defines the starting location in the longitudinal direction for the segment of the disc's surface included in the primitive.
Truncate along Circumference	Lets you define a circumferential limit (less than 360°) for the disc primitive. The smaller section between Outer Radius – start position and Outer Radius – end position is kept.
Outer Radius – 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 disc surface included in the primitive.Note: For clarity, select or create the point on the circumference of the circular surface.
Truncate Radially	Lets you define a radial limit (less than the outer radius ) for the disc primitive.
Inner Radius	Appears only if Truncate Radially is selected.Lets you select or create a point to define the truncating limit in the radial direction for the segment of the disc surface included in the primitive.Note: For clarity, select or create the point on the circular surface. The value for Inner Radius must always be less than Outer Radius – end position.

Parameter	Definition
	Center
	Z Axis
	Outer Radius
	Truncate Along Circumference
	Truncate Radially
