# April 2026 Updates
This April, working with drawings in the editor has become even more convenient.
In particular **the layer management feature has been significantly revamped**so
the settings you often adjust 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 **Floor Management**and **Resource Management**, two pages.
**Before Changes**Previously, floor height settings, adding/creating floors, and checking the spaces and items included in each floor were all gathered on one page.
**After Changes**, on the floor management page, you can quickly adjust detailed settings such as not only floor height but also actual 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 view the spaces and items included in each floor at a glance.
***
On the floor management panel **Net Area**and **Net Area + Area Including Internal/External Walls** you can check the information right away and directly edit the overall floor size.
However, please note that if you change the overall floor size, the wall, floor, and ceiling finishes edited in the finish editor will be reset to their default values,
and ceiling structures created in the ceiling editor will be deleted.
When you make changes, the following notice message will appear.
***
**Slab thickness** can also be set in the same floor management panel. When you change the input value, it is immediately applied to the entire floor.
Slab Thickness 1
Slab Thickness 1000
**Wall and floor transparency**can now also be adjusted individually.
You can view it in both 2D and 3D, making it useful for checking drawings or for presentations.
Wall transparency 0 (2D)
Wall transparency 0 (3D)
Floor transparency 0 (2D)
Floor transparency 0 (3D)
***
There are also changes in Render Studio.
**Interior/Exterior Wall Hide Option**has been newly added, so wall transparency (culling) settings are directly reflected 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
Hide External Walls Render
Hide Internal Walls Render (+ Wall Transparency)
Hide Both Internal and External Walls
***
**Specification Editor**now has ceiling content added.
A complete ceiling plan for the designed drawing is automatically generated, allowing you to see the placement 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 **Linear 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.
***
Lastly **the Parametric Editor**has also been improved. You can now copy and paste modeling, parametric component items, and all items, and it works properly across different browsers (e.g., Chrome ↔ Edge).

```
GET https://docs.archisketch.com/guide/intro-1/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.
