Press the left mouse button after positioning the cursor at the desired location for one corner of the rubber box. SURFCAM anchors one corner of the rubber box.
Drag the mouse to a point diagonally opposite the first point until all elements to process are entirely within the rubber-band box. The box stretches in the direction you move the mouse.
Press the left mouse button. SURFCAM will select the elements that are completely enclosed with the box and process them accordingly.
