Cylinder 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 cylinder by assigning values to parameters in relation to a coordinate system you specify.Points: Lets you define the cylinder 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 cylinder located by the Start Angle and End Angle. At the end of each traversal between circumferential limits the element sequence continues at the Start Angle the next layer up.
Along Height	Defines the number of elements along the vertical height of the cylinder. The number of elements defines the number of layers in the mesh.Note: No mesh is created on the flat circular surfaces.
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.

Cylinder 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.
Radius	Lets you define the radius of the cylinder. The software measures the radius as a distance from the origin.Note: The base of the cylinder is always on the X-Y plane.
Base Height	Defines the base height as a distance from the origin along the Z-axis. Use this option to offset the base of the primitive.
Top Height	Defines the top height as a distance from the origin along the Z-axis. The difference between the Base Height and the Top Height defines the height of the cylinder.
Start Angle / End Angle	Defines a circumferential segment of the cylinder body measured from the X-axis. The segment of the cylinder 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.

Parameter	Definition
	Radius
	Base Height
	Top Height
	Start Angle
	End angle

Cylinder primitive defined by points

Option	Description
Definition
Base Center	Lets you select or create a point to define the center of the base of the cylinder.Click Point Constructor to use the Point dialog box to create a new point. See Point dialog box for more information.Note: The base of the cylinder is always on the X-Y plane.
Base Radius – start position	Lets you select or create a point to define the radius of the cylinder. The point also defines the starting location in the circumferential direction for the segment of the cylindrical surface included in the primitive.
Top Center	Lets you select or create a point to define the height of the cylinder using the centre of the upper circular face of the cylinder as a distance from the Base Center.
Truncate along Circumference	Lets you define a circumferential limit (less than 360°) for the cylinder primitive.
Base 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 cylindrical surface included in the primitive. Note: For clarity, select or create the point on the circumference of the circular surface.

Parameter	Definition
	Base Center
	Base Radius - start position
	Top Center
	Truncate Along Circumference
	End Angle
