You can specify a relative change in view magnification by using Zoom Scale and typing a factor followed by the X character.
- the view center remains in the center of the display window.
- scale factors larger than 1.0 have a zoom in effect while factors less than 1.0 have a zoom out effect.
- Zoom In (2X) and Zoom Out (0.5X) use the Scale option of Zoom.
- you will find these 2 menu options in the View + Zoom pulldown menu and in the Zoom toolbar (or Standard toolbar flyout).
Practice with ZOOM Scale
1- Continue in the same drawing from the previous exercise.
2- Pick View + Zoom + Out
3- Examine your command line history.
Specify corner of window, enter a scale factor (nX or nXP), or [All/Center/Dynamic/Extents/Previous/Scale/Window] <real time>: .5x
AutoCAD automatically supplies a factor of .5x to the first Zoom command prompt when you select the Zoom Out menu.
4- Pick View + Zoom + Scale and then enter 2X at the keyboard when prompted for the scale factor.
Specify corner of window, enter a scale factor (nX or nXP), or [All/Center/Dynamic/Extents/Previous/Scale/Window] <real time>: _s Enter a scale factor (nX or nXP): 2X ↵
You manually used a factor of 2X to zoom in again.
- this scale factor reverses the 0.5X factor that was used in the previous step when you selected the Zoom Out menu option.
AutoCAD supplied the _s keyword to use the Scale option automatically when you picked View + Zoom + Scale
- but you can also simply enter a scale factor at the first Zoom prompt without having to explicitly use the Scale option.
You use the X suffix to scale view magnification relative to the current view magnification
- you can also use an XP suffix to scale view magnification relative to paper space
- you will learn about paper space when you work with the Introduction To Layouts document.
5- Remain in this drawing for the next exercise.
