Drawing a Spiral Using User-Defined Primitives

Ansys provides you with a DLL to define the parameters of a rectangular spiral.

  1. Click Draw > User Defined Primitive > SysLib > Examples > RectangularSpiral.

    2. The Create User Defined Part dialog box appears. The Parameters tab permits you to see edit the parameters. An Info tab contains information about the user defined primitive, its purpose, the company/author who created it, the date created and the version number.

  2. Specify the values for the following parameters:

    Xpos

    Type the location of the starting point in the X direction.

    Ypos

    Type the location of the starting point in the Y direction.

    TurnSep

    Type the separation distance between turns.

    Turns

    Type the number of complete revolutions the object will make around the vector

    Width

    Type a value for the width of the spiral.

    Height

    Type a value for the height of the spiral. If you specify the height as zero, the modeler draws a sheet object.


  3. Click OK.

    This creates the primitive and displays the Properties dialog for the new object.
