There are numerous cases where you use dummy objects to aid creation/modification of geometry in LightTools. One common example is the use of a dummy sphere (or a point/coordinate system object) as a specific reference point (also known as a tag point for selection) for complex objects that do not have a desirable reference point for selection. By selecting the dummy reference first, and then selecting the complex object(s), we can use our reference object as the selection point for commands like Copy, Move, Rectangular/Circular Array, etc. One undesirable effect of this approach is the creation of additional reference objects that can add clutter to the model. This tip highlights how to use the Data Access Helper utility to make the selection process easier for you in order to remove additional objects.
Consider the case where you want to create a circular array of LEDs using a base LED model, which does not have a desirable reference point for selection/arraying. By adding a dummy sphere as a reference point, we can create the array easily. The remaining issue is how to remove the additional dummy objects resulting from the array operation.
