TREPEDIA 2026
Software for Stairs & Railings. From idea to production-ready drawing in minutes. No more days spent on measurements, drawings, and calculations. Enter your dimensions, and TREPEDIA automatically generates complete technical drawings. Every detail is calculated, every angle is correct.

You don’t need any training or manuals for the software—it’s simple and intuitive to use.
Suitable for all common straight, spiral, or mixed floor plans, with up to 3 corners, including Z-shaped, spiral, or spiral-spindle staircases.
Each corner can be designed as a spiral or a landing; intermediate landings are also possible.
Equally suitable for residential staircases as well as industrial staircases (or staircases on machines and equipment).
All common construction types made of profiles or sheet metal, with side stringers (curved, sawtooth, stepped, made of profile) or top stringers (sawtooth, stepped, made of profile), including single-stringer staircases.
All details that frequently arise in day-to-day work—such as angled entry/exit points, fixed landing heights, varying tread widths, etc.—are modeled.
Railings are available in many variations for stairs or, for example, as balcony railings.
Custom designs for railings can be saved and reused.
Direct drawing output via printer, dimensioned for manufacturing and including a title block—no plotter required.
Attractive 3D visualization for review and for the client.
Export options to laser/CNC or other CAD programs as DXF/DWG files or in STEP/IGES format.
3D solid data in STEP or IGES format for further processing in other 3D programs or for CNC machining.
