Primitive Feature: Sphere

Function

Create a Sphere of the Shell or Solid type.

Call

Geometry > Primitive Feature > Sphere

<Sphere dialog box>

Center XYZ

Specify the coordinates of the center of a Sphere.  The coordinates can be directly entered in the dialog box, or a point can be selected in the Work Plane with the mouse.  When a point is entered by a mouse click while the Use Snap function is turned off, only the coordinates of the center point will be entered and the Sphere will not be generated automatically.
 

Radius

Specify the Radius of the Sphere.
 

Angle1

Specify a starting angle of the vertical section plane of the Sphere.
 

Angle2

Specify an ending angle of the vertical section plane of the Sphere.
 

Anlgle3

Specify a revolution angle of the vertical section plane.
 

GCS

Specify the coordinates of the Center XYZ in 3-dimensional space in the Global Coordinate System.
 

WCS

Specify the X- and Y- coordinates of the Center XYZ relative to the Work Plane Coordinate System.  Thus, the center of the Sphere will be located at the Work Plane.
 

Name

Enter the name of the Sphere to be created.

Use Snap

The Use Snap function automatically places a Sphere centered on the point of a mouse click upon the mouse click.
 

Solid

This option creates a Sphere of the Solid type.  If it is unchecked, a Sphere of the Shell type will be created.

Notes

A revolved geometric shape such as Cone and Sphere causes a singular vertex at its apex during mesh generation. At the singular vertex, a number of element nodes comes together. Consequently, it often yields abnormal analysis result. This singular vertex is inevitable for every type of revolved shapes due to revolution axis. Therefore, it must be corrected after it was generated manually using Re-meshing Feature.
