Drawing a Spiral Using User Defined Primitives
Ansys provides you with a DLL and a Python script to define the parameters of a rectangular spiral. Before you draw a spiral, you can specify the coordinate system, and you can set the drawing plane as Z, Y, or Z, or you can edit the plane in the properties.
- From the menu bar, click Draw > User Defined Primitive > Examples > RectangularSpiral (DLL) or Rectangular Spiral (Python).
The User Defined Primitive Operation dialog box appears. The Parameters tab permits you to see and 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.
- Specify the values for the following parameters:
Xpos
X location of the starting point.
Ypos
Y location of the starting point.
Dist
The separation distance between turns.
Turns
The number of complete revolutions the object will make around the vector
Width
The width of the spiral.
Thickness
The thickness/height of the spiral. If you specify the thickness as zero, the modeler draws a
- Click OK.
This creates the primitive and displays the Properties dialog box for the new object.
To see newly created DLLs, click Draw > User Defined Primitive > Update Menu.
To see the primitives that you have created, click Draw > User Defined Primitive > UserLib.
