Trepedia 5.2.2 (Smart Pattern & 3D Stair Design Integration)

Overview of Trepedia 5.2.2

Trepedia is an automated CAD software solution designed specifically for the architectural and construction industries to accelerate stair design workflows. Unlike general-purpose CAD platforms that require extensive training and manual drawing, Trepedia operates on a parametric input model. Users select a floor plan type—such as straight, L-shaped, U-shaped, Z-shaped, or spiral—and then enter the relevant dimensions. The software immediately generates a complete stair model, including floor plans, stringers or profiles, steps, step supports, and a bill of materials with all quantities and cuts.

The software was originally developed by an industry practitioner with over 30 years of experience in stair construction software, and it is now maintained and further developed by Draw2design and I-Program. Trepedia is used by approximately 750 businesses of various sizes, including metalworking shops, stair builders, carpenters, architects, and freelance craftsmen.

Trepedia is available in modular form. Users can license the stair module, the railing module, or a combined package that includes both. This modular structure allows businesses to invest only in the functionality they need.

Key Features

Parametric Stair Construction

The core of Trepedia is its fully parametric construction engine. Rather than drawing lines and arcs manually, users define measurements and properties, and the software generates every drawing automatically. If a wall measurement changes because plaster turns out to be thicker than expected, you simply adjust that single dimension and the entire stair—including steps, stringers, and railings—is recalculated instantly. This approach eliminates the need to redraw or recalculate anything by hand.

Automatic Technical Drawings

Trepedia automatically produces a complete set of technical documentation for each stair project. These include:

• Floor plan views

• Stringer and profile drawings

• Step drawings with exact dimensions

• Step support details

• 3D views for visualization

• Bill of materials with all quantities and cut specifications

Step drawings are specifically optimized for easy marking and ripping, with dimensions prepared so that step manufacturers can produce components directly from Trepedia output. Many step manufacturers already work with Trepedia-compatible drawings.

Real-Time 3D Visualization

Every measurement change is reflected immediately in a full 3D model. This real-time preview allows users to show clients a realistic representation of the stair before any material is ordered or cut. The 3D view can be kept running alongside the 2D workspace, providing continuous visual feedback throughout the design process.

Comprehensive Stair Type Library

Trepedia includes a complete library of common stair floor plan types. Supported configurations include:

• Straight stairs

• Stairs with one corner

• Stairs with two corners (including half-turn or landing variants)

• Stairs with two opposite corners (Z-shape)

• Stairs with three corners

• Curved stairs

• Spiral and helical stairs

All common construction types are supported, including profile-based and sheet metal designs, stringers in various forms (curved, sawtooth, stepped, or profile), and saddle-mounted configurations. Single-stringer stairs are also included.

Material and Step Type Flexibility

The software supports all standard step materials:

• Wooden steps

• Sheet metal steps

• Grating steps

• Natural stone steps

Step dimensions are optimized for marking and can be adjusted individually. Material optimization features help reduce waste during production.

Integrated Standards Compliance

Trepedia includes integrated compliance checking according to DIN 18065, the German standard for stair construction. Country-specific requirements and standards can be applied on a project-by-project basis, making the software suitable for international use.

Railing and Balustrade Design

The modular railing module allows users to design matching railing systems alongside stair structures. Realistic railing options are available in the 3D view, ensuring that the complete stair-and-railing assembly can be visualized and documented together.

What’s New in the Latest Version

Trepedia 5.2.2 represents the current release of the software. While the version numbering indicates incremental refinement rather than a major architectural overhaul, several areas have been enhanced:

• IFC interface improvements: The IFC export functionality has been optimized for better integration with BIM environments such as Revit and HiCAD. Users can now save IFC files directly from Trepedia and open them with the IFC interface in HiCAD, enabling seamless data transfer between design and production environments.

• HiCAD integration enhancements: The interface between Trepedia and HiCAD has been refined. Drilling patterns, cuts, and notches generated in Trepedia are transferred to HiCAD exactly as designed, preserving precision through the entire workflow.

• Expanded export capabilities: The software continues to support the full range of industry-standard export formats, including DXF, DWG, IFC, STEP, and IGES, as well as direct export to HiCAD and Tenado.

• Continued development under Draw2design: Since the acquisition by Draw2design, the software has undergone continuous technical and visual improvements. The original developer remains actively involved to ensure a smooth transition and continued domain expertise.

No additional CAD software is required to run Trepedia. It is a standalone application, though it integrates with HiCAD and Tenado for users who have those platforms.

How to Use Trepedia: A Step-by-Step Guide

Trepedia’s workflow is designed to be intuitive even for users with no CAD experience. The typical design process follows these steps:

Step 1: Select a Floor Plan Type

Begin by choosing the appropriate stair configuration from the built-in library. Options include straight stairs, L-shaped, U-shaped, Z-shaped, curved, and spiral designs. Trepedia starts with a completed stair model based on your selected floor plan, so you are not starting from a blank canvas.

Step 2: Enter Your Measurements

Input the relevant dimensions for your project: floor-to-floor height, available space, step width, and any specific constraints. The software guides you through the required inputs step by step.

Step 3: Review the 2D and 3D Output

As you enter measurements, Trepedia automatically generates complete 2D technical drawings and a live 3D preview. Every change is reflected instantly in both views.

Step 4: Adjust Details and Properties

Modify step types, stringer configurations, railing designs, and connection details as needed. The parametric engine recalculates everything automatically with each adjustment.

Step 5: Verify Standards Compliance

Check that the design meets the relevant building standards. Trepedia includes integrated compliance checking for DIN 18065 and can accommodate country-specific requirements.

Step 6: Export Production Files

Once the design is complete, export the necessary files. Trepedia supports:

• 2D export: DXF, DWG

• 3D export: STEP, IGES

• BIM export: IFC

• Direct export: HiCAD, Tenado

These files can be used directly for CNC machining, laser cutting, or further processing in CAD environments.
