- (A nested command)
-
- 1. (CHAR) options: w-window, f-factor <w>
- if reply is `w'
- 2. (POINT) first point of zoom
- 3. (POINT) opposite point of zoom (press <ENTER> for another first pt)
- if reply is `f'
- 2. (NUM) factor (greater than 1) <2>

- Description:
- This command zooms in on the geometric model.
- Select one of the two options: zoom by specifying a window on the screen (`w'
- the default), or by specifying a zoom factor (`f'). If you selected the window
- option, pick two opposite points of the window. The specified area is enlarged
- to fill the screen, and the scale is modified appropriately. If you pick
- an incorrect position for the first point, press <ENTER> and you will be
- prompted for a new first point.
-
-
- If you selected the zoom factor option, specify a value greater than 0 (the
- default is 2). The current scale will be multiplied by this factor. The
- location of the screen center point remains fixed.
-
- Examples: \zoom w 4 4 0 8 8 0
-
- Result: The square area defined between 4 4 0 and 880 fills the screen and the
- scale is adjusted.
-
- \zoom f 4
-
- Result: If the current scale was 1:100, the new scale will be 1:25. The
- location of the screen center point remains fixed.
