TREPEDIA v5.2.2
TREPEDIA is a professional staircase design and calculation software developed for stair builders, metalworking companies, architects, engineers, fabricators, and construction professionals. The software simplifies the entire stair design process, from entering basic building dimensions to creating detailed 2D drawings, 3D models, production drawings, and CAD/BIM files.
With TREPEDIA, you can quickly calculate and design different types of stairs while maintaining precise dimensions and checking the design against applicable construction standards.
Staircase Design and Calculation
Simply enter the basic dimensions of the building and staircase area, and TREPEDIA automatically calculates the key parameters of the staircase,
including:
Rise and going dimensions
Number of steps
Staircase angle and inclination
Step dimensions and overall staircase geometry
Stringer and carriage dimensions
Other important construction parameters
When you change any dimension, TREPEDIA automatically recalculates the entire staircase, helping you make design adjustments quickly without having to recalculate everything manually.
2D Drawings and 3D Staircase Models
TREPEDIA automatically generates accurate 2D staircase drawings and 3D models based on the entered dimensions. This makes it easier to visualize the finished staircase, verify the design, and prepare the project for manufacturing and installation.
The software also supports the creation of production drawings with the information required for fabrication.
Staircase Standards and Compliance
TREPEDIA can check staircase designs against applicable standards, including DIN 18065 for stairs and DIN EN ISO 14122-3 for industrial stairs.
This helps designers and manufacturers verify important staircase dimensions and design parameters during the planning process.
CAD, CNC, 3D and BIM Export
For integration with professional design and manufacturing workflows, TREPEDIA supports several widely used file formats:
DXF / DWG – for CAD design and CNC manufacturing
STEP / IGES – for 3D modeling and engineering workflows
IFC – for BIM (Building Information Modeling) applications
This allows staircase designs to be transferred directly to CAD, CNC, 3D modeling, and BIM workflows.
Supported Staircase Configurations
TREPEDIA supports a wide range of staircase types and construction configurations, including:
Straight stairs
Quarter-turn stairs
Z-shaped stairs
Spiral stairs
Central-stringer stairs
Different stringer and carriage constructions
The software is suitable for designing both traditional and more complex staircase structures for residential, commercial, industrial, and architectural projects.
Professional Staircase Design Software
With automated staircase calculations, 2D and 3D modeling, standards checking, production drawings, and CAD/CNC/BIM export, TREPEDIA provides a complete workflow for professional staircase design and manufacturing.
It is particularly useful for stair manufacturers, metalworking companies, architects, engineers, fabricators, and construction professionals who need accurate staircase calculations and production-ready design data.
