Locator Model Set the Bounding Area The Bounding Area tells the Locator Model where to look for the model. Anything not included inside the Bounding Area will not be considered a part of the model. For this reason, it is best to set the Bounding Area as close to the model part as possible, without cropping any edges of the part. The model Bounding Area can be set by dragging the corners of the green box in the display window, or by modifying the numbers in the Bounding Area boxes (bottom, top, left, right). You can either enter the appropriate numbers, or use the up/down arrows for each value.
When dragging the edges of the Bounding Area, it is usually best to magnify the view by click- ing the magnifying glass icon. Setting the Origin The model's origin tells the software where the part should be picked up, and in what ori- entation. You can set the origin in three ways: l Manually drag the yellow origin indicator to the spot on the part where you want it. Adjust the orientation by dragging one of the origin arrowheads (X or Y). This may be the best method for irregularly-shaped parts, particularly if their mass is off-center. The coordinates and orientation of the origin can be manually entered in the Coordin- ate System pane. l Click Center in the Coordinate System pane.
This will center the origin in the model's bounding box. Depending on the part shape, and how closely you set the bounding box, this may not be appropriate. l Select a row in the Model Contents pane, and click Center in the Coordinate System pane. Each row in the Model Contents pane represents a found instance. When you select a row, that instance will be highlighted in red. If there are multiple instances, you can use this to select and delete any unwanted instances. When a Model Contents row is selected, you can delete the associated instance by clicking Delete. When there is only one instance, select the row in the Model Contents pane and click Center in the Coordinate System pane.
The origin will be centered on the instance. Click Accept when you are done setting the Bounding Area and origin. Cropping the Model You can crop the image containing the model to just the bounded area by clicking Crop. This eliminates any instances that are near the model, but not actually a part of the model.
