Creating an Axis

You can create an axis feature from an element.

This task shows you how to:

Before you begin: Create a 3D shape containing a circle, an ellipse, an oblong curve or a revolution surface.

Circle

You can create an axis using a circle.

  1. Click Axis in the Wireframe toolbar (Line-Axis sub-toolbar).

    The Axis Definition dialog box appears.

  2. In the Element box, select the circle or portion of circle.



  3. In the Direction box, select the direction, when not normal to the surface.

  4. In the Axis type list select one of the options:

    • Aligned with reference direction

    • Normal to reference direction

    • Normal to circle

  5. Click OK to create the axis.

    The element (identified as Axis.xxx) is added to the specification tree.

Ellipse

You can create an axis using an ellipse.

  1. Click Axis .

    The Axis Definition dialog box appears.

  2. In the Element box, select the ellipse or portion of ellipse.



  3. In the Axis type list select one of the options:

    • Major axis

    • Minor axis

    • Normal to ellipse

  4. Click OK to create the axis.

    The element (identified as Axis.xxx) is added to the specification tree.

Oblong Curve

You can create an axis using an oblong curve.

  1. Click Axis .

    The Axis Definition dialog box appears.

  2. In the Element box, select the oblong curve.



  3. In the Axis type list select one of the options:

    • Major axis

    • Minor axis

    • Normal to oblong

  4. Click OK to create the axis.

    The element (identified as Axis.xxx) is added to the specification tree.

Revolution Surface

You can create an axis using a revolute.

  1. Click Axis .

    The Axis Definition dialog box appears.

  2. In the Element box, select the revolution surface or portion of revolution surface.



    The revolution surface's axis is used, therefore the axis type list is disabled.



  3. Click OK to create the axis.

    The element (identified as Axis.xxx) is added to the specification tree.

Important: The axis can be displayed in the 3D geometry, either infinite or limited to the geometry block of the input element. This option is to be parameterized in Tools > Options > Shape > Generative Shape Design > General. For more information refer to Accessing and Customizing Settings.
