# CAD Upload
Archisketch supports CAD drawing upload.\
However, before uploading, the drawing's layers must be organized to meet Archisketch's requirements.\
If the layers are not organized, errors may occur, so please refer to the guide below and organize them before uploading.
{% hint style="warning" %}
This feature is available to Archisketch paid customers.
{% endhint %}
## Example
## Uploadable file format (DXF)
* File format: DXF
* Maximum file size: 10MB
## Organizing layers in CAD
Archisketch can recognize only 4 layers in total.\
Before uploading the drawing, please set the layer names in CAD as follows. (Case insensitive)
| Type | Layer name |
| ------- | -------------------------- |
| Walls | **`wall`** |
| Doors | **`door`** |
| Windows | **`window`** |
| Columns | **`line`** or **`column`** |
### Walls
Set the layer name to wall and draw the wall 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's hard to check whether the wall is broken, try applying Hatch!
If one Hatch is applied cleanly, you can consider the wall line organization complete!
{% endhint %}
**Additional features**
* You can specify the wall height in advance 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.
* After setting the layer name to window, insert it at the desired location as shown below.
{% hint style="warning" %}
Caution) Windows that are not converted into blocks cannot be loaded in the Archisketch editor.
{% endhint %}
### Columns
Set the layer name to line or column and draw a polygon.
{% hint style="warning" %}
Caution) A polygon must be made up of straight lines or circles, and it must be a shape whose start and end are connected.
{% endhint %}
Pillar creation requirements
* Circular pillar
* If the polygon has 20 or more points
* Converted to \[circular pillar]
* Square pillar
* If the polygon has 4 points and is a rectangle
* Converted to \[square pillar]
* Other shapes
* If the polygon has 5 to 19 points
* Converted to \[Design Library > Architecture/Material Editor]
Notes
If a layer contains a shape that does not meet the requirements, it will not be uploaded properly.
### Save the file
* Please save the file format as dxf. Other formats do not support the upload feature.
## Upload in Archisketch
Drawing upload method
* Proceed in the order of \[Drawing Upload] → \[CAD Upload] → \[Select File].
* After that, a window for selecting layers will appear.
* You can turn only the desired layers on and off.
* Once selection is complete, press the \[Upload] button at the bottom right.
## Edit in the editor
Uploaded drawings are converted into Archisketch format, so you can use various Archisketch features such as wall editing, product placement, and rendering.
## Edit pillars
Once upload is complete, select a pillar and then modify 'Properties > Height' to adjust the pillar to the desired 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-en/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.
