# ZOOM in AutoCAD

> How AutoCAD's ZOOM (Z) works: Extents, Window, Previous, Scale with nX, Object and All, the mouse wheel, zooming inside a command. Try it free online.

ZOOM makes the view larger or smaller; nothing in the drawing moves or changes size. Its first prompt takes a corner, which starts a window, a scale factor, or an option. Typed with an apostrophe, `'ZOOM` or `'Z`, it works inside another command, which goes on after it. The mouse wheel zooms in and out about the cursor, and a double-click of the wheel button is ZOOM Extents. Each ZOOM is an undo step, consecutive ones a single step, so `U` takes the view back too.

- **Command:** `ZOOM`
- **Aliases:** `Z`
- **Panel:** [Inquiry & view](https://mellowcad.com/docs/commands.md#inquiry)
- **Try it:** [Open the editor](/draw), type `Z` and press Enter.

## At the command line

The engine draws it and writes its history as you would type it: the prompts in AutoCAD 2027's order, with the same option letters.

A plate with a small hole near its corner: ZOOM Extents, then a window round the hole, which then fills the view.

```text
Command: ZOOM
Specify corner of window, enter a scale factor (nX or nXP), or [All/Extents/Previous/Scale/Window/Object]: E
Command: ZOOM
Specify corner of window, enter a scale factor (nX or nXP), or [All/Extents/Previous/Scale/Window/Object]: 0,0
Specify opposite corner: 24,24
```

## Options

### `All` (`A`)

Frames everything drawn, as `Extents` does.

### `Extents` (`E`)

Frames everything drawn, as large as the window allows. With nothing drawn, it says `Regenerating model.`, and typed inside another command it refuses with `** Requires a regen, cannot be transparent.`, as AutoCAD's does.

### `Previous` (`P`)

Goes back to the view before, up to 20 views back. With none left: `No previous view saved.`.

### `Scale` (`S`)

A factor: `2X` zooms twice as close as the current view, `0.5X` half as close, and `2` without the X twice the scale of ZOOM All's view. `nXP`, paper space's factor, is read as `nX`: there is only model space here. A factor typed at the first prompt does the same without choosing the option.

### `Window` (`W`)

Two corners, picked or dragged, frame that rectangle. A corner picked at the first prompt does the same.

### `Object` (`O`)

Frames the objects you select, or those selected before ZOOM.

## What it does not do yet

Realtime: Enter at the first prompt ends ZOOM, where AutoCAD starts zooming with the mouse; the wheel does that here. Dynamic, Center and the hidden Left and Vmax.

## Questions

### What is the shortcut for ZOOM in AutoCAD?

`Z`, then Enter or Space. The full name works too, and `_ZOOM` in any language of AutoCAD. `Z` then `E` is ZOOM Extents.

### How do I zoom to fit the whole drawing?

`Extents`: type `Z`, Enter, `E`, Enter. Or double-click the mouse wheel button.

### What does ZOOM XP mean in AutoCAD?

`nXP` zooms a layout viewport to a scale relative to paper space: `1/50XP` shows the model at 1:50 on the sheet. MellowCAD has no layouts, so `XP` is read as `X`.

### How do I zoom to an object in AutoCAD?

Choose `Object` and select it, or select it first and then run ZOOM Object: the view frames it.

### How do I go back to the previous view?

`Previous`, again and again for the views before it, up to 20.
