Introduction:
In the world of construction and engineering, precision and efficiency are non-negotiable—especially in steel detailing. Tekla Structures, a powerful Building Information Modeling (BIM) software developed by Trimble, is widely adopted by professionals for its ability to create intelligent, constructible 3D models of steel structures. For beginners, understanding how to use Tekla effectively can open up vast opportunities in steel detailing and fabrication workflows.
This blog is a complete step-by-step guide for beginners looking to learn Tekla Structural Steel 3D Modelling for structural steel detailing. Whether you're a civil engineer, drafter, or student stepping into the world of steel, this guide will help you get started the right way.
Step 1: Understanding the Tekla Interface
Before jumping into modelling, it's crucial to get comfortable with the Tekla user interface. The Tekla Structures workspace consists of:
- Modeling Window: The main 3D/2D area where you construct your models.
- Ribbon: Toolbars grouped by function (e.g., steel, concrete, drawings).
- Property Pane: Shows and edits object properties.
- Object Browser: Lists model elements for filtering and navigation.
- Quick Launch: Search and access commands fast.
Familiarity with the interface enhances efficiency and reduces errors as you begin creating detailed steel models.
Step 2: Starting a New Tekla Project
To begin a new project in Tekla:
- Launch Tekla Structures.
- Select a suitable environment and role (e.g., Steel Detailing – Imperial or Metric).
- Create a new model file and name your project (e.g., “Industrial_Shed_Model_01”).
- Set the model location, and Tekla will create folders and database files automatically.
Always choose the correct environment and settings, as they affect units, profiles, and default templates used during modelling and drawing.
Step 3: Setting Up Grids and Work Planes
Grids serve as a structural reference and help maintain alignment during modelling. To define grids:
- Use Grid → Create Grid from the ribbon.
- Set the number of bays in X, Y, and Z directions.
- Label grid lines for clarity.
Work planes can also be rotated and adjusted to model sloped beams or unusual geometries.
Step 4: Adding Steel Members
Start modelling by adding key steel elements:
Primary Steel Elements
- Beams: Use the Beam tool to place columns, rafters, and girders.
- Columns: Usually placed first, based on grid intersections.
Secondary Steel Members
- Bracings: Diagonal members for stability.
- Joists & Purlins: Support secondary loads.
For each element, you’ll specify parameters such as profile, material, rotation, and elevation using the Property Pane. Tekla includes libraries of steel profiles according to country-specific standards.
Step 5: Applying Connections
One of Tekla’s strongest features is automated connections. Tekla includes an intelligent library of customizable steel connections like:
- End Plate
- Moment Connections
- Base Plates
- Clip Angles
To apply a connection:
- Select the components (e.g., a beam and a column).
- Use Applications & Components window to drag and drop the connection type.
- Modify connection properties to match your design intent.
Tekla will automatically place bolts, cuts, and welds based on connection logic.
Step 6: Checking the Model for Errors
Before generating drawings, validate your model:
- Use Clash Check to detect overlapping components.
- Run Numbering to assign part and assembly marks.
- Check welds and bolts for conflicts or missing information.
These checks help avoid costly fabrication issues and reduce site rework.
Step 7: Creating Shop Drawings
Once your model is clean and numbered, you can produce fabrication drawings:
- Select parts or assemblies in the model.
- Right-click and choose Create Drawing.
- Choose Single-Part, Assembly, or GA Drawing.
- Customize your drawing layout using drawing properties.
Tekla allows full control over dimensions, marks, weld symbols, part lists, and drawing views.
Step 8: Generating Reports & Bill of Materials (BOM)
Tekla supports various types of reports essential for fabrication:
- Part lists
- Assembly lists
- Bolt lists
- Weld logs
Go to Drawings & Reports → Reports, choose your template, and export to Excel or PDF. These reports are used for ordering, logistics, and shop floor instructions.
Step 9: Exporting Files for CNC and BIM Coordination
Tekla supports various export formats:
- NC Files (DSTV): For automated fabrication on CNC machines.
- IFC Files: For BIM coordination with architects, MEP, and clients.
- DWG/DXF: For CAD-based workflows.
Use Export → NC Files or Export → IFC based on your client or shop requirements.
Step 10: Best Practices for Beginners
Here are some practical tips to speed up your learning curve:
- Use Templates: Standardize drawings and reports with reusable templates.
- Backup Often: Use Tekla's autosave and model backup features.
- Stay Organized: Use phases and filters to manage large models.
- Join Tekla Forums: Learn from the global community of detailers and engineers.
- Practice Real Projects: Start with small industrial or portal frame buildings to gain confidence.
