# Setting ceiling and floor heights

## Change Floor Reference Height

If you want to create level differences by space, just change the floor reference height.

* Click the space floor.
* In the right-side \[Space Details], change the floor reference height.\
  The floor height is set to 0 by default, and you can set level differences by room.\
  The floor reference height can be adjusted with +/- signs, and you can create a step in spaces like bathrooms or entryways to lower the floor surface below the reference.
* Even if you change the floor reference, furniture positions will not change automatically.\
  You need to manually adjust each item’s \[Height from Floor], and to change them all at once, use multi-select Shift+drag or, when grouped, edit \[Height from Floor] in the right-side \[Group Details].

{% hint style="info" %}
Since floor height can only be adjusted by space,

if the entrance is connected to the living room without an interior door, it is difficult to lower only the entrance floor separately.

If you want to create a stepped effect within the same space, you need to use the \[Architecture/Materials Editor] feature or separate modeling products.
{% endhint %}

## Change Room Height

To adjust the ceiling height of a room, click the room floor and then adjust the room height in the right-side \[Space Details].\
The wall length and ceiling position change together on a room-by-room basis.

* If you want to change the ceiling height for the entire floor plan, not by room, make the change in bulk from the left tab \[Floor Management] → \[Floor Height]. ([Manage Floors](/guide/user-en/make-project/floor-management.md))

## Other Functions

### Match Space Height

If you uncheck and then recheck \[Match Space Height], the room wall heights will be adjusted automatically.\
This feature batch-adjusts wall heights based on the ceiling height (room height) when the wall heights in a room are not uniform.

### Hide Ceiling

If you want to create a space without a ceiling, such as a terrace or outdoor area, turn off the \[Hide Ceiling] checkbox.

* Click the floor or ceiling surface.
* In the right-side \[Space Details], check the \[Hide Ceiling] checkbox.

## Frequently Asked Questions

#### The ceiling looks open.

Did you lower the wall height below the ceiling?\
If you lower the wall height to create a partition-wall-like effect, that ceiling surface will appear open.\
When drawing a wall lower than the ceiling, please use 'Draw Rectangular Column' instead of 'Draw Wall'.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.archisketch.com/guide/user-en/make-project/ceiling-floor-height.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
