What is the Ceiling Editor?
The Ceiling Editor is a feature that helps you create a variety of interior looks, such as tray ceilings, curtain boxes, indirect lighting installations, and ceiling moldings. If you want to make your space more lively and realistic, be sure to use the Ceiling Editor! When you render, you’ll be able to create great results. 🌟

Entering the Ceiling Editor
Here’s how to enter the Ceiling Editor.
In the 3D view, click the ceiling surface, then right-click and select Ceiling Editor

Ceiling Editor Layout
When you open the Ceiling Editor, the screen is laid out like this.

Plan: The editor screen where you can edit the ceiling surface in 2D
3D Viewer: An area where you can see the applied result in 3D in real time
Using the mouse wheel lets you zoom in/out and pan in both the 2D and 3D screens.
Library panel: A library where you can apply finishing materials and moldings
Area settings: The section where you configure steps, materials, indirect lighting, and more.
Drawing a Tray Ceiling
Step 1. Draw guide lines (Shortcut: T)
You can easily draw a tray ceiling area using guide lines.
Click near the wall, then move the mouse to the desired position.
If you enter a number and press Enter, you can draw the guide line precisely.
You can also copy or delete a guide line by clicking it. Press Esc to exit guide-line drawing mode.

Step 2. Set the area
You can set the area using the line, curve, rectangle, or circle tools.

Line: A closed area is created when lines meet.
Curve: Specify the first and second points, then set the radius to draw a curve.
Rectangle: Click the first point and second point to adjust the size. You can also press the Tab key to enter the width and height numerically.
Circle: Set the center point and the radius to draw a circle.

Step 3. Apply curvature (rounding)
You can add smooth curves to corners or angled parts.
Apply to all corners at once
Click the center of the area, then right-click.
Click the Round button, then set the radius value or move the mouse to adjust the curvature.

Apply only to specific corners
Click the corner where you want to apply curvature, then right-click.
Click the Round button, then adjust the radius.

Step 4. Apply a step
You can adjust the step with +/- values.
To raise the area: enter a + number
To lower the area: enter a - number
The default ceiling thickness is set to 300 mm. If you want to raise it higher, just modify the ceiling thickness.
Step 5. Install indirect lighting
When you switch indirect lighting from [Off → On], the settings below become active.
Indirect light box size
You can set the size of the light box. Enter the desired number in the W/H fields.
Indirect light box shape
Indirect lighting can be installed in two forms:
L-shape: Wrapped one more time around the indirect light, providing softer and more subtle lighting.
Flat shape: The indirect light is installed with the wing wall extended slightly more, allowing for a cleaner-looking space.
Indirect lighting brightness
You can adjust the brightness of the indirect lighting shown in the rendering. Use it appropriately according to the surrounding light or the amount of light coming in from outside.
Indirect lighting color
You can change the indirect lighting color to any color you want.

When indirect lighting is installed, the previously set area expands by the W size. Therefore, before installation, please set the area with the width in mind.
Individual indirect lighting settings
Indirect lighting can be configured individually by clicking each line.
If you click inside the area, all lines included in that area are selected.
If you click an individual line, only the selected line becomes active.
By selecting lines individually like this, you can also change colors or apply individual settings.

Creating a Curtain Box
Set the curtain box area.
Set a step by entering the desired number for the area.

Want to add indirect lighting to the curtain box?
Just like with a tray ceiling, turn on the indirect lighting after setting the area and step [Area settings → Step settings]. However, please note that lighting will not be installed in areas that touch the wall.
Applying finishing materials
You can separate the ceiling surface and apply different finishing materials to each section.
Use the area drawing tool to divide the areas you want to apply.
Select the desired material from the finishing material library in the left panel and apply it.
Create a more distinctive space with a variety of finishing materials!

Molding Library
You can add stylish accents to the ceiling using the molding library.
Click the molding shape you want in the molding library.
If you click the wall in the plan where you want to apply molding, the molding will be applied along the selected wall all at once.

Changing the molding material
By default, the molding finish uses a wood material.
Click the material change icon.
You can change it by selecting the desired material from the left library.
Try changing the atmosphere of the space by combining different molding shapes and materials!

Frequently Asked Questions
Can’t I move the position of the area drawn on the ceiling?
Currently, changing the position is difficult. Please set the area accurately when drawing it for the first time!
Is there no floor baseboard feature?
It’s still in preparation. We’re working hard to make it possible to apply steps and baseboards to floors, just like in the Ceiling Editor. Please look forward to the future improvements of Archisketch!
