# PLAN in AutoCAD

> How AutoCAD's PLAN looks straight down on the current UCS, a saved one or the world's: Current ucs, Ucs, World, and how to get back to plan. Try it free.

PLAN looks straight down on the XY plane of a UCS, with its X axis pointing right: the plan view, as you drew it. It asks which UCS — the current one, a saved one or the world's — and Enter takes the current one. Then it frames the whole drawing and says `Regenerating model.`.

Nothing in the drawing moves, and the UCS stays as it was: PLAN only turns the view. It is one undo step, so `U` takes the view back, and [`ZOOM`](https://mellowcad.com/docs/commands/zoom.md) `Previous` steps back to the view before. It is the way back to the plan after [`3DORBIT`](https://mellowcad.com/docs/commands/3dorbit.md) or an isometric [`VIEW`](https://mellowcad.com/docs/commands/view.md). MellowCAD's 3D is solids only, and still partial.

## 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.

The stepped block seen from the south-west with its UCS turned 30 degrees about Z: PLAN and Enter look straight down on that UCS, its X axis to the right, so the block shows turned.

## Options

### `Current ucs` (`C`)

The plan of the current UCS, the default. After [`UCS`](https://mellowcad.com/docs/commands/ucs.md) turned the UCS 30 degrees about Z, the drawing shows turned 30 degrees clockwise, so that the UCS's X axis points right; after a UCS on a sloping face, it looks square onto that face.

### `Ucs` (`U`)

The plan of a UCS saved with [`UCS`](https://mellowcad.com/docs/commands/ucs.md)'s `NAmed`, which you type by name. For a name that is not saved it says it cannot find that UCS and asks again; `?` lists the saved ones, as UCS does, and asks again too. The current UCS does not change.

### `World` (`W`)

The plan of the world coordinate system: the drawing as it was at the start, X to the right and Y up, whatever the current UCS is, which stays as it was.

## What it does not do yet

With nothing drawn, PLAN keeps the zoom where it was, where AutoCAD frames the drawing limits.

## Questions

### How do I get back to plan view in AutoCAD?

Type `PLAN` and press Enter twice: the second Enter takes `Current`. If the UCS is turned and you want the world's plan, choose `World` instead.

### What is the UCS plan command?

PLAN with `Current`: it looks down on the current UCS, its X axis to the right. Turn the UCS first with [`UCS`](https://mellowcad.com/docs/commands/ucs.md), then run PLAN and press Enter twice, and you draw on the turned plan as if it were square.

### Why is my drawing rotated in plan view?

The view is the plan of a turned UCS. Run PLAN and choose `World` to see the drawing with the world's X to the right again; [`UCS`](https://mellowcad.com/docs/commands/ucs.md) and Enter set the UCS back to World too.

### Does PLAN change the UCS?

No. It only turns the view; the UCS stays as it was. [`VIEW`](https://mellowcad.com/docs/commands/view.md)'s orthographic views are the ones that turn the UCS as well.
