# CAD Upload
Archisketch supports CAD drawing upload.\
However, before uploading, the drawing layers must be organized according to Archisketch’s requirements.\
If the layers are not organized, errors may occur, so please be sure to refer to the guide below and organize them before uploading.
{% hint style="warning" %}
This feature is available to Archisketch paid customers.
{% endhint %}
## Example
## Supported file format for upload (DXF)
* File format: DXF
* Maximum file size: 10MB
## Organizing layers in CAD
Archisketch can recognize only 4 layers in total.\
Before uploading the drawing, set the layer names in CAD as shown below. (Can be set regardless of case)
| Type | Layer name |
| ------- | -------------------------- |
| Walls | **`wall`** |
| Doors | **`door`** |
| Windows | **`window`** |
| Columns | **`line`** or **`column`** |
### Walls
Set the layer name to wall and draw the walls as shown below.
{% hint style="warning" %}
Caution) The wall lines must touch exactly. Otherwise, wall detection will not work properly.
Caution) The spaces between walls must not be closed.
Caution) Curved walls are not supported.
{% endhint %}
{% hint style="info" %}
If it is hard to tell whether a wall is broken, try applying a Hatch!
If one Hatch is applied cleanly, you can consider the wall line cleanup complete!
{% endhint %}
**Additional features**
* You can preset the wall height in CAD!\
If you set the layer name like wall\_2800, the wall height will be automatically applied as 2800mm in the Archisketch editor.
### Doors
* Create the door as a block as shown below.
* Set the layer name to door and place the block at the door location.
### Windows
* Create the window as a block as shown below.
* Set the layer name to window and insert it at the desired location as shown below.
{% hint style="warning" %}
Caution) Windows that are not blocked cannot be imported into the Archisketch editor.
{% endhint %}
### Columns
Set the layer name to line or column and draw a polygon.
{% hint style="warning" %}
Caution) The polygon must consist of straight lines or circles, and must be a shape with the beginning and end connected.
{% endhint %}
Column creation requirements
* Round column
* When the polygon has 20 or more points
* Converted to \[Round Column]
* Square column
* When it has 4 points and is a rectangle
* Converted to \[Square Column]
* Other shapes
* When the polygon has 5 to 19 points
* Converted to \[Design Library > Architecture/Material Editor]
Notes
If the layer includes shapes that do not meet the requirements, it will not upload properly.
### Save the file
* Please make sure to save the file format as dxf. Other formats do not support the upload feature.
## Upload in Archisketch
How to upload a drawing
* Proceed in this order: \[Drawing Upload] → \[CAD Upload] → \[Select File].
* After that, a window for selecting layers will appear.
* You can turn only the layers you want on or off.
* Once the selection is complete, click the \[Upload] button at the bottom right.
## Edit in the editor
Uploaded drawings are converted into Archisketch format, allowing you to use various Archisketch features such as wall editing, product placement, and rendering.
## Edit columns
Once the upload is complete, you can select a column and adjust it to the desired height by editing 'Properties > Height'.

## 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-guide/expert-feature/cad-upload.md?ask=&goal=
```
`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.
