# April 2026 Update
This April, working with drawings in the editor has become even more convenient.
In particular **the layer management feature was greatly revamped**and,
the settings that are often adjusted during the design process can now be handled quickly in one place.
***
The biggest change is that the existing Layer Management page has been split into **Layer Management**and **Resource Management**, two separate pages.
**Before change**Layer height settings, layer addition/creation, and checking the spaces and items included in each layer were all gathered on one page.
**After change**On the Layer Management page, you can directly adjust not only layer height but also detailed settings such as floor area, slab thickness, and wall/floor transparency, and this panel is always visible on the right, so your workflow isn't interrupted.
The Resource Management page has been separated into a dedicated screen where you can get an overall view of the spaces and items included in each layer.
***
On the Layer Management panel, **Net area** and **Net area + area including interior/exterior walls** you can check information right away and even directly edit the overall layer size.
However, please note that if you change the overall layer size, the wall, floor, and ceiling finishes you edited in the finish editor will be reset to their default values,
and the ceiling structures created in the ceiling editor will be deleted.
When making changes, a notice like the one below will be displayed.
***
**Slab thickness** can also be set from the same Layer Management panel. When you change the input value, it is immediately applied to the entire layer.
Slab thickness 1
Slab thickness 1000
**Wall and floor transparency**can now also be adjusted individually.
You can check it in both 2D and 3D, making it 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, and the wall transparency (culling) setting is now reflected as-is in the rendering results.
You can render in various combinations, such as making walls transparent, hiding only interior walls, or hiding only exterior walls.
Wall transparency render
Exterior wall hiding render
Interior wall hiding render (+wall transparency)
Hide both interior and exterior walls
***
**Specification Editor**has also gained ceiling content.
The full ceiling plan for 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 who work in 3D mode.
What used to be possible only in 2D mode **array copy**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 properties feature**has been added, allowing you to select multiple items and set angles, positions, heights, and more all at once.
***
Finally **Parametric Editor**has also been improved. You can now copy and paste models, parametric component items, and entire items, and it works properly even across 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.
