IN

Purpose:

To enable a user to visually 'zoom' into a selected region and thus reduce the apparent scale, resulting in graphic entities appearing to be larger.

Instructions:

In the View menu, click Zoom, then In.

Position the cursor at a suitable position on the screen and click the left-hand button on the mouse.

Move the cursor to a new position. The system responds by continuously drawing a rectangular box. This box is positioned and proportioned according to the selected first point and the current cursor position becoming the opposite corner along a diagonal.

When the cursor is in the required position click the left-hand button again.

The system responds by linearly scaling the box size up to fit the screen size, with the center of the box coinciding with the new center of the display window and the display contents becoming increased in size accordingly.

(See also screen icon for 'short-cut' entry.)

Options:

There are no options available within this process.

Result:

The apparent size of objects, including geometry and text, displayed on the screen is increased according to the user's requirements. Additionally the graphic elements may appear in a different location on the screen.
