Using Copy with Move/Rotate

TracePro can be used to create arrays of objects through the Edit|Move and Edit|Rotate dialogs. One or more objects may be duplicated from a reference object. The geometry and TracePro properties will be transferred to the duplicated object.

This example will demonstrate a method to create a linear and rotational lens array. Arrays of reflecting objects may be created in TracePro RC using this example as a template.

1.Create a lens by selecting Insert|Lens Element.

2.Enter the following values for the cylinder and press Insert to create the object:

3.Thickness: 3

4.Surface 1 Radius: 12

FIGURE 9.39 - Lens Element Dialog

5.Trace a fan of rays by setting the parameters of the Define|Grid Source to an Outer radius of 25, Grid Pattern to Cross, and X points to 1. The other options may be set to the default values.

6.Trace the rays by pressing the Trace This Rays button. See Figure 9.40.

7.Open the Edit|Move dialog.

8.Select the Lens by pressing Edit|Select|Object and clicking on the lens with the mouse.

9.Create a second lens by entering 16 for Y Center in the Move Selection Dialog. Press the Copy button. See Figure 9.41.

10.Create a third lens by entering -32 for the Y Center in the Move Selection Dialog. Press the Copy button. Notice that the selection move from the first to second and then third object.

11. Trace another grid raytrace. See Figure 9.42.

12.Next create the rotational arrays by changing the TracePro view to a XY profile by selection View|Profile|XY.

13.If the bottom lens is not highlighted, select the bottom lens. See Figure 9.43. 14.Open the Edit|Object|Rotate dialog.

15.Enter 60 for Rotation Angle and change the Axis to About Z. See Figure 9.44. 16.Press the Copy button twice to create two more lenses.

17.Skip the top lens by changing the Rotation Angle to 120, press Copy. 18.Add one more lens by returning the Rotation Angle to 60 and press Copy. 19.The resulting Lens Array in shown in Figure 9.45.
