This post shares our current development direction after the Zircon3D v2.2 release. Current Focus: Routing System After v2.2, our next development focus will be the routing system. The idea is to make Zircon3D able to visualize connected systems inside or around a building, such as Energy systems, solar panels, home batteries, EV chargers, main panels and inverters, water pipes, sewer lines, greenhouse irrigation systems, HVAC ducting or airflow paths, and other routing-style systems in the future. The goal is to make complex building data easier to understand visually from a 3D layout, showing where things are, how they are connected, and how data or resources flow through the system.

Current: 2026-S2 Routing System - Draw and visualize connected routes such as energy lines, wires, pipes, ducts, or irrigation paths in 3D. Static Floating Card - Display static text, labels, notes, or images above objects in the 3D view. Template System - Create reusable templates for buildings, floors, rooms, or groups of objects. Room Box View with Sensor Data - Allow room colors to represent values such as occupancy, air quality, or other sensor data. Copy and Paste - Clone objects more easily using shortcut keys or pointer-based actions. More Usability Improvements - Continue improving editing workflow, object placement, visual controls, and general usability. Suggest a Feature We’d love to hear your ideas and feedback.

Patch Update: Zircon3D v2.2.1 — 2026-05-15 We released a small patch update for Zircon3D v2.2. New Feature Added Project Tools: support exporting and importing Zircon3D space-plan / floorplan data. Bug Fixes Fixed an issue where switching edit mode did not reset Box View correctly. Fixed behavior issues related to View Settings, Floating Cards, and Sensor Card Display. The new import/export feature can be useful when you need to move, back up, or share a floorplan between Zircon3D projects. How to import/export a floorplan in Zircon3D This feature is only for exporting floorplan data from Zircon3D and importing it back into Zircon3D. It is not for importing files from other design systems. Open Zircon3D in Home Assistant. Select your project, then click Edit to open the Designer. In the bottom-left bar, open Project Tools. Choose Import Project or Export Project. When importing, select the project file exported from Zircon3D. After importing, click Save to keep the imported floorplan, or press Undo to discard the changes.

We’re excited to announce Zircon3D v2.1, bringing several usability improvements, better visualization controls, and refinements based on user feedback. This update focuses on improving the experience on mobile devices, heatmap visualization, and floorplan editing precision. Below are the highlights of this release. ou can also check out the video overview of this release here: https://youtu.be/3_3LnBEamoQ 3D View Control Buttons (Mobile & Tablet Friendly) To improve usability on touch devices, we added on-screen control buttons for common camera actions: Rotate view Pan the scene Zoom in/out These controls make it much easier to navigate the 3D scene on tablets and phones, especially for wall-mounted dashboards or touchscreen environments. [image: 1773259455149-cff316b0-19f7-40fb-adae-3d6de016e816-image.png] Data Card Display & Heatmap Overlay Improvements We improved how data cards interact with heatmaps and added new display controls to reduce visual clutter when monitoring your building, including: Better readability when heatmaps are active Reduced overlapping between heatmaps and data panels Cleaner visualization in environments with many sensors These improvements make the heatmap view clearer and easier to interpret, especially in complex buildings with dense sensor deployments. [image: 1773327570807-f42d4a1e-1a7e-40a6-bd0f-0a9ce81aec46-image.png] Card Display Modes Three modes are available: Detailed – Show all sensor data panels (current behavior). Compact – Only show data panels related to the currently selected heatmap value. Hidden – Hide all floating data panels for a clean heatmap visualization. This makes it easier to focus on specific environmental metrics without unrelated sensors cluttering the view. Additional Display Options Two new options provide further control over what appears in the 3D scene: Show Action Cards – Toggle the display of interactive device cards such as switches or cameras. These appear as small icon bubbles in the scene. Enable Occlusion – Prevent data panels and action icons from rendering through floors. Elements hidden behind floors will now remain hidden, improving visual realism in multi-floor buildings. [image: 1773259779610-404d8b17-a290-4d10-a928-ffbbae75c935-image.png] Sensor Icons for Better International Usability Zircon3D now supports automatic sensor icons for common values such as: Temperature Humidity These icons appear in the data panel, making sensor types easier to identify even when entity names are not in English. [image: 1773328247950-921fb6e7-cbf8-4a92-a019-f3aafe005e22-image.png] Disable Wall/Room Auto-Attach Helper by Holding Shift When editing floorplans, Zircon3D normally uses an auto-attach helper to snap walls and objects together. For more precise editing, you can now: Hold the Shift key to resize rooms freely without auto-attach helper. This allows finer control when adjusting room shapes or sizes. Preview Button for Quick Viewing A new Preview button has been added to the top toolbar. This allows you to instantly preview your building visualization without manually switching to another view tab. You can quickly check how your floorplan and devices appear in the final scene while editing. This makes the workflow faster when designing your building, letting you switch between editing and viewing at any time with a single click. [image: 1773327687088-5c145f3d-02b4-4c0a-8bd5-0aa2499a2f4b-image.png] Automatic Switching Between Editing Modes Zircon3D now automatically switches between Building Edit Mode and Object Edit Mode based on the element you select in the scene. Building Edit Mode – for editing structural elements such as walls and rooms. Object Edit Mode – for editing objects such as furniture, doors, windows, and devices. This removes the need to manually change editing modes and makes the editing workflow more intuitive when building your home or facility model. Bug Fixes & Performance Improvements As always, this release also includes: Various bug fixes Performance improvements General stability enhancements Feedback Welcome Many of these improvements were inspired by community feedback. If you have suggestions or feature ideas, feel free to share them in the forum.

Hi everyone! Zircon3D v1.2 is now live. This release introduces several new features, including customizable stairs, wall openings, and standalone divider walls. We’ve also added support for wall-mounted items like lights and framed pictures, as well as ceiling-mounted lights. On the Home Assistant side, the enhanced Monitoring panel now supports template sensors with a configured unique_id, KNX integrated entities and other standalone entities from Home Assistant, along with improved search and filter capabilities. Pro users can now change floor materials, and as always, we’ve included various bug fixes and improvements. 1. How to Add Customizable Stairs You can now add fully customizable stairs under Building Parts, with support for straight, L-shaped, and U-shaped designs. To customize a stair: Select the stair and open the Properties Panel on the right. Enable the Override toggle to unlock advanced settings. Adjust the Width, Tread Depth, Riser Height, and the overall Rise and Run. For L-shaped stairs, toggle between Left and Right turns. U-shaped stairs also support Left and Right configurations. This gives you flexible control to design the staircase that fits your layout perfectly. https://youtu.be/qd_3kGRQCvk 2. How to Add Divider Walls and Wall Openings To add a standalone divider or create an opening in a wall, go to the Building Parts tab and open the Rooms sub-tab. Divider Walls: Drag and drop a Divider onto the floorplan to create a separate wall. You can resize, reposition, and rotate it using the position helper to match your preferred layout. Wall Openings: Drag and drop the Opening component onto any existing wall. This creates an opening within the wall, which you can resize by dragging the blue handles. To remove the opening, select the parent room and use the right-side Properties Panel. These tools offer more flexibility for refining your floorplan structure. 3. Wall-Mounted and Ceiling-Mounted Items You can now easily mount objects directly to walls and ceilings: Ceiling Lights: Select a ceiling light and drag it over your floorplan. When you hover near a ceiling, it will highlight, drop the light to mount it in place. Wall-Mounted Items: Wall-mounted lights and framed pictures can be dragged onto any wall. The system will automatically align and attach them to the wall surface. This makes it simple to add decorative or functional elements directly onto your structure. https://youtu.be/qZKqv394oz0 4. Enhanced Monitoring Panel with Search & Filter, Supporting Template and KNX This update brings expanded compatibility to Zircon3D’s Monitoring panel. We now support Template Sensors (with unique_id), KNX integrated entities, and other standalone entities from Home Assistant. When adding your monitored devices to the floorplan, you can: Drag and drop the Home Assistant Entities or devices from the Monitoring Panel directly onto the floor, or Map them to furniture models for a more immersive experience. These features help you build a smarter, more visual representation of your environment. If the sensor represents a temperature value, make sure to also specify: device_class: "temperature" A valid unit_of_measurement (e.g., "°C") Here’s an example configuration: template: - sensor: - name: "temperature_difference" unique_id: "temp_diff" state: > {% set t1 = states('sensor.aqara_temp_humidity_sensor_temperature_2') | float(0) %} {% set t2 = states('sensor.aqara_temp_humidity_sensor_temperature') | float(0) %} {{ (t1 - t2) | round(2) }} unit_of_measurement: "°C" device_class: "temperature" This will allow Zircon3D to recognize and display the template sensor correctly. https://youtu.be/2vl8UVddpx8 5. Floor Material Customization (Pro Users Only) Pro users can now customize floor materials for each space. To change a floor’s material: Select the floor from the Navigation Tree on the left. Then, choose a material from the Properties Panel on the right. This allows greater control over the look and feel of each room in your 3D model.
