Primitive Shape dialog box

Type

Specifies the shape to use.

  • The orientation of a primitive shape and the direction of the size specifications use the Work Coordinate System, which can be moved during primitive creation using the Transform tool.

  • Sphere, Cylinder, Block, and Torus initially create a B-surface sheet body.

If the cage remains closed when you finish NX Realize Shape, it will be a B-surface solid body.

  • Rectangle and Circle create a B-surface sheet body.

Sphere

  • Creates a cage for a sphere.

  • Size handle available.

Cylinder

  • Creates a cage for a cylinder.

  • Size and Height handles available.

Block

  • Creates a cage for a block.

  • Length, Width, and Height handles available.

Circle

  • Creates a cage for a circle.

  • Size handle available.

Rectangle

  • Creates a cage for a rectangle.

  • Length, and Width handles available.

Torus

  • Creates a cage for a torus

  • Inner and Outer diameter handles available.

Center

Available for Circle, Sphere, Cylinder, and Torus primitive types.

Specify Point

Lets you specify the origin by selecting any location on the XY plane of the Work Coordinate System, or you can drag the origin handle anywhere on the work plane.

The Point Dialog is available for specifying the origin.

Origin

Available for Rectangle and Block primitive types.

Specify Point

Lets you specify the origin by selecting any location on the XY plane of the Work Coordinate System, or you can drag the origin handle anywhere on the work plane.

The Point Dialog is available for specifying the origin.

Size

Note: For any shape primitive, on-screen handles are provided for dragging all the sizes.

Size

Type

Lets you specify

Sphere

Size

Cylinder

Size and Height.

Block

Length (in the XC direction) Width (in the YC direction) Height (in the ZC direction)

Circle

Size of the circle.

Rectangle

Length (in the XC direction) Width (in the YC direction)

Torus

Inner and Outer sizes of a Torus.

Segments

Segment specification is based on the shape of each primitive.

Primitive shape

Example of Segments input

Cylinder

  • Linear = 2

  • Circular = 6

Block

  • Linear X = 1

  • Linear Y = 2

  • Linear Z = 3

Circle

  • Circular = 6

Rectangle

  • Linear X = 2

  • Linear Y = 3

Torus

  • Radial = 8

  • Circular = 4

The Sphere primitive is a special case that uses subdivision levels instead of segmentation.

Subdivision levels are progressively determined by dividing each cage face of a subdivision level in half in both directions.

Subdivision Level = Base

6 cage faces

Subdivision Level = First

24 cage faces

Subdivision Level = Second

96 cage faces
