To draw a line using two model space viewports, you start the line in the
current viewport, make another viewport current by clicking within it, and
then specify the endpoint of the line in the second viewport. In a large
drawing, you can use this method to draw a line from a detail in one corner
to a detail in a distant corner.
To make a viewport current
■ Click anywhere within the viewport border.
To cycle through viewports without clicking
■ Press Ctrl+ R repeatedly.
