# April 2026 Updates
This April, handling drawings in the editor has become even more convenient.
In particular **the layer management function has been significantly revamped**and,
so the settings that are often adjusted during the design process can now be handled quickly in one place.
***
The most noticeable change is that the existing layer management page has been split into **Layer Management**and **Resource Management**, two separate pages.
**Before Change**There, layer height settings, adding/creating layers, and checking the spaces and items included in each layer were all gathered on one page.
**After Change**, in the Layer Management page, you can adjust not only the layer height but also detailed settings such as net area, slab thickness, and wall/floor transparency right away, and this panel is always visible on the right, so your workflow is not interrupted.
The Resource Management page has been separated into a dedicated screen where you can review the spaces and items included in each layer overall.
***
In the Layer Management panel, **Net Area**and **Net Area + Included Area of Interior/Exterior Walls** you can check the information right away and also directly edit the overall layer size.
However, please note that if you change the overall layer size,
the wall, floor, and ceiling finishes edited in the finish material editor will be reset to their default values, and
the ceiling structures created with the ceiling editor will be deleted.
***
**Slab thickness** can also be set in the same Layer Management panel. When you change the input value, it is immediately reflected across the entire layer.
Slab Thickness 1
Slab Thickness 1000
**Wall and floor transparency**can now also be adjusted individually.
Since it can be checked in both 2D and 3D, it is useful for drawing review or presentations.
Wall transparency 0 (2D)
Wall transparency 0 (3D)
Floor transparency 0 (2D)
Floor transparency 0 (3D)
***
There are also changes in Render Studio.
**Hide interior/exterior walls option**has been newly added, so the wall transparency (culling) settings are reflected directly in the rendering results.
You can render in various combinations, such as making walls transparent, hiding only the interior walls, or hiding only the exterior walls.
Wall Transparency Render
Exterior Wall Hide Render
Interior Wall Hide Render (+Wall Transparency)
Hide Both Interior and Exterior Walls
***
**Specification Editor**has also added ceiling contents.
The full ceiling plan of the designed drawing is automatically generated, allowing you to see the placement status of ceiling items at a glance.
***
There is also good news for those working in 3D mode.
What used to be possible only in 2D mode **copying in a row**is now supported in 3D mode as well.
Before — available only in 2D mode
After — available in 3D mode as well
***
It has also become more convenient when handling multiple items at once.
**group property function**has been added, allowing you to select multiple items and set the angle, position, height, and more all at once.
***
Lastly **the Parametric Editor**has also been improved. You can now copy and paste models, parametric component items, and all items, and it works properly even between different browsers (e.g., Chrome ↔ Edge).

## 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/intro-en/update-note/2026/202604.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.
