NOTE

Buttons are active when the text on the button is black (rather than gray). This means that you can launch the

associated function by clicking on the button with the mouse.

The Center and Test options will only be available if you have already loaded a fiducial and a model already

exists for this fiducial.

If you have selected a fiducial the fiducial number and the fiducial name will appear in the display field.

If you click on the

Center

button the

Test fiducial

The

Center

function determines via software the center of the fiducial. The parameters for the function - these

are the edges of the fiducial structure - you can select via a dialog. The system draws edge line markings as

suggestions at possible edge positions.

With the arrow keys shift the current edge line marking designated in the header.

With

Return

you can accept the position of the suggested edge line marking or the one whose position

you changed. The system will then show you the next edge line marking. The sequence in which interroga-

tion takes place is ’Fiducial edge left’, ’Fiducial edge right’, ’Fiducial edge top’ and lastly ’Fiducial edge bot-

tom’. This notation appears in the header.

The results of fiducial centering are indicated by a cross. The x and y offset values of the fiducial center will be

entered in the fiducial data field.

PLEASE NOTE:

An incorrectly centered fiducial will cause a placement offset.

Press the Esc key to quit the option and return to the Test fiducial menu.
