🌟 Key Highlights of Rebro 2026 – The Automation Leap

Rebro 2026 introduced groundbreaking automation features that significantly reduce repetitive manual work:

🔧 Automatic Vertical System Drawing (Patent Pending) Simply define shafts and floors, then let Rebro batch-generate vertical piping, ducts, and cable trays across the entire building. What used to take hours of careful routing can now be completed in minutes.

💨 Automatic Smoke Exhaust Route Connection (Patent Pending) Select smoke-exhaust ducts and outlets — Rebro automatically creates optimized routes. Multi-selection support allows batch processing of entire systems, dramatically accelerating fire-safety design.

✏️ Trace Drawing Convert existing 2D CAD lines into intelligent 3D pipes and ducts in one click. Rebro automatically reads purpose symbols, sizes, and layers from the drawing, making 2D-to-3D conversion faster and more accurate than ever.

⚡ Automatic Path Selection in Wiring Management Define start points, end points, and layers — Rebro calculates and selects the optimal electrical routing path automatically.

📊 Enhanced Data Tools

• Custom properties now support calculation formulas
• Improved Excel-based layer editing
• Stronger data-link and batch processing capabilities
• Better cloud collaboration and external reference management

These core innovations make Rebro 2026 one of the most productive MEP BIM solutions available for architectural equipment design in Japan and beyond.
