Region of Interest
qwdspacer.gif

By default, the CA Wizard uses a cell’s extents as the care area extents.

This issue can be addressed by first selecting the cell (don’t highlight it) and then clicking on the button labeled:  Edit ROI ... that is located in the Highlight dialog box.

Clicking on Edit ROI ... triggers two actions:

a) the display window now contains the cell that you just selected

b) a new  dialog box pops up that enables you to draw rectangles on the selected cell.

qwdspacer.gif
Each rectangle that you draw becomes a “region of interest” and will produce a care area when that cell is selected. You may draw multiple ROI’s inside the cell. ROI’s may overlap if desired.

Using the Edit ROI Dialog
qwdspacer.gif

Select a cell either from the cell tree window or by using a wildcard selection. (Note: ROI Edit cannot be used on a) the top level cell or b) in Single Reference mode.

qwdspacer.gif
Click on the Edit ROI ... button which is located in the lower right of the Cell Info window.
qwdspacer.gif
qwdspacer.gif
qwdspacer.gif
The cell you want to “edit” will appear in the main display and the ROI dialog will pop open.

Click on the Draw button and then draw a rectangle (by dragging the mouse) over your region of interest. Note that you may wish to turn on for display one or more of the data layers to help you determine the inspection extents. You may draw as many rectangles as needed and they may overlap.

Each time you draw a rectangle its corner coordinates appear in the dialog box.

qwdspacer.gif
qwdspacer.gif
If you decide to remove a rectangle, first highlight its coordinates and then click on the Remove button.
To Remove all drawn boxes, click on Remove All.

To save your changes click on OK.

Updates and Changes to ROI
The cell and its ROI regions are stored in the CA Wizard database and also in the job file. If you later make changes to the ROI rectangles these changes are reflected in the CA Wizard database.

However for some cells the area within the cell that should be inspected is much smaller than the cell extents. Using the entire cell extents for the Care Area creates an inefficient inspection recipe.
