Room Arranger 10.3.6 (released February 12, 2026) is a specialized CAD application designed for room, apartment, and house floor planning. Known for its small footprint and remarkably intuitive 2D interface, this version fully integrates with the Liquid Glass design language of Windows 11 and macOS Sequoia. The software bridges the gap between basic sketching and professional architecture by allowing users to draw floor plans and instantly visualize them in a 3D environment, complete with sun shadows and realistic textures.
Regarding searches for a “Crack” or “License Key” for version 10.3.6.748, it is important to clarify as a supportive AI that Room Arranger is developed by a single independent developer (Jan Adamec) and utilizes a Fair Use Trial Model. The software is officially free for 30 days, providing full access to all features, including saving and printing. After this period, the “full” (unlimited) version costs a one-time fee of $24.95 USD, which includes a lifetime license for all future releases. Unauthorized “cracks” for this software are frequently identified as Trojan horses or adware, specifically targeting users of lightweight design tools. For a secure and ethically sound experience, it is recommended to use the official 30-day trial, which allows you to complete most short-term projects legally and without cost.
Key Features:
-
LiDAR Room Scanning: (iOS/iPad Pro) Use the LiDAR camera to instantly scan a physical room and send the 3D geometry directly to your desktop for further arrangement.
-
Sun Shadows: Real-time calculation of shadows based on the time of day and geographical location, helping you plan for natural light.
-
Extensive Object Library: Includes everything from standard furniture to specific items like SUVs, SUVs, and patio heaters, with the ability to define custom object dimensions.
-
Multi-Floor Projects: Design entire houses with multiple levels; users can toggle floor visibility and view stairs or openings between levels in 3D.
-
Scale Printing: Print your finished floor plans to exact architectural scales (e.g., 1:50 or 1:100) for physical construction use.
What’s New?
-
Liquid Glass Design: A complete UI overhaul that adopts modern translucent design elements, improving aesthetic integration with the latest operating systems.
-
Enhanced 3D Performance: Optimized for M3/M4 chips on Mac and NVIDIA RTX 50-series GPUs, resolving previous crash issues in high-detail 3D viewports.
-
snapping to Walls: Improved logic for objects snapped to walls, ensuring they maintain their relative positions even after room transformations or resizing.
-
Floorplan Image Calibration: Faster and more accurate “blueprint tracing” tools that allow you to import an image of a plan and scale it to real-world units in seconds.
-
Autosave in Wall Editor: To prevent data loss during complex drafting, the Wall Editor now features background autosaving.
