    Cloning of Assembly Drawings in Tekla

    Cloning of Assembly Drawings in Tekla is the Smartest Way to Improve Detailing Efficiency

    In structural steel detailing, efficiency and accuracy are critical to delivering projects on time. As projects grow larger and more complex, detailers must find smarter ways to manage repetitive components and maintain consistency across drawings. One powerful feature that helps achieve this in Tekla Structures is Assembly Drawing Cloning.

    Cloning assembly drawings is a highly effective method that allows detailers to duplicate an existing assembly drawing and apply it to similar assemblies within the model. Instead of creating drawings from scratch every time, detailers can reuse a well-configured drawing layout, saving significant time while maintaining uniform standards across the project.

    In steel structures, many assemblies such as beams, columns, bracing members, and connection components often share similar configurations. When these assemblies are modeled with comparable geometry and detailing requirements, cloning becomes an invaluable tool. By copying an existing drawing and adapting it automatically to another assembly, Tekla helps detailers maintain consistency in dimensions, views, marks, and annotations.

    Another advantage of cloning is its ability to intelligently adapt to small variations between assemblies. Tekla automatically adjusts views, dimensions, and annotations to match the geometry of the new assembly. This allows detailers to reuse drawings even when there are minor differences in member length, hole positions, or connection details

    Why Locknuts Are the Unsung Heroes of Anchor Bolt Integrity

    Anchor bolts are the literal foundation of structural stability. They secure steel columns, heavy machinery, and critical structural components to concrete foundations, resisting uplift, shear, and dynamic forces.

    But even the strongest anchor bolt is only as reliable as its ability to stay tight.

    In industrial environments where vibration, movement, and thermal cycling are constant, relying on a standard nut alone is often not enough. This is where locknuts become a non-negotiable component of anchor bolt assemblies.

    The Hidden Risk: Vibration-Induced Loosening

    When we think about structural failures, we often imagine snapped steel or crumbling concrete. However, one of the most common—and preventable—failure points is vibration-induced loosening. Enter the locknut – the small but mighty component that ensures your anchor bolts stay steadfast.

    The Mechanics of Loosening

    Standard nuts rely on the friction between the bolt threads and the nut threads, maintained by the tension (clamp load) of the bolt. However, two main factors can compromise this:

    Thermal Expansion: Fluctuating temperatures cause the bolt and the fixture to expand and contract, periodically reducing the clamp load.

    Vibration: Constant motion from machinery or wind loads can cause minute “slips” in the threads.

    What is a Locknut and Why Does it Matter for Anchor Bolts?

    A locknut is a specialized fastening device designed to resist loosening when subjected to vibration and torque. Unlike standard nuts, which rely solely on friction created by initial tension, locknuts incorporate various mechanisms to maintain their grip, even when external forces try to reduce that tension.

    Conclusion

    Don’t let a $2.00 part jeopardize a $200,000 project. Using high-quality locknuts on your anchor bolts ensures longevity, reduces maintenance costs, and—most importantly—guarantees structural safety.

  • Difference Between TEKLA “Export IFC” and IFC4

    Difference Between TEKLA “Export IFC” and IFC4

    When we export models from TEKLA Structures, we mainly see two options:

    • Export IFC (this mostly means IFC2x3 format)
    • IFC4 Export

    Both formats serve the same purpose—model interoperability—but they work differently, support different levels of data, and offer different quality of geometry.

    In this blog, we explore the key differences, benefits, and when to use each format.

    1. What is “Export IFC” (IFC2x3)?

    This is the old IFC format used by most companies for many years.

    Key points

    • Works in almost all BIM software
    • Shows Geometry is basic and sometimes rough
    • Limited property information
    • The File size is Bigger

    Best For

    ✔ General coordination
    ✔ Clients who request IFC2x3
    ✔ Old software compatibility

    2. What is “IFC4 Export”?

    This is the newer and more advanced format.

    Key Points

    • Geometry looks cleaner and smoother
    • Curved members (Hollow sections, pipes, elbows, etc.) look perfect
    • More detailed data (bolts, welds, assemblies)
    • Smaller file size in many cases
    • Better for new BIM tools

    Best For

    ✔ Modern BIM tools
    ✔ Better visual quality
    ✔ Detailed model sharing

    3. Quick Comparison

    convert IFC object to Steel MemberWork wellCan’t convert

    4. Which One Should You Use?

    • Use Export IFC (IFC2x3) if the client asks for it or if compatibility is important.
    • Use IFC4 if you want cleaner geometry and more detailed information.

    5. Final Summary

    • IFC2x3 (Export IFC) → Best for compatibility
    • IFC4 → Best for quality and smooth geometry

    If your client or BIM Execution Plan (BEP) does not specify the format, use IFC4 for best geometry

  • How TEK1 Solved the Complicated Star Node Puzzle in Great EMU in the Sky

    How TEK1 Solved the Complicated Star Node Puzzle in Great EMU in the Sky

    At TEK1, we believe great detailing is more than just precision—it’s about understanding real-world challenges and turning complexity into clarity.

    The Challenge

    The Great EMU in the Sky project presented one of the most unique and technically demanding structures we’ve ever worked on—a 30-metre-wide globe made up of 128 intricate “star nodes” connecting the bracing members.

    These nodes weren’t ordinary joints. Each featured 5 or 6 connection points and came in three different CHS sizes, with every arm set at unique, non-repeating angles.

    For the fabrication team, this posed a significant challenge:

    • 128 Complex Star Nodes, each with custom angles
    • Inconsistent geometries
    • Time-consuming and difficult to fabricate accurately

    Even with precise 3D modelling, the practicality of fabrication was proving to be a serious bottleneck. Something had to change.

    The Turning Point

    That’s when TEK1 took the initiative.

    Rather than simply delivering a model and walking away, we engaged directly with the fabricator to understand the issue from their perspective. We realized that even the most accurate detailing wasn’t enough—what the team needed was smarter, fabrication-friendly solutions.

    The Solution

    Our detailing team re-engineered how the star nodes were documented, presented, and ultimately fabricated. Key solutions included:

    • ✅ Custom fabrication jig design: We developed a dedicated jig that allowed star nodes to be fabricated with greater ease and precision, regardless of the angle configuration.
    • ✅ Standardized node sub-groups: We grouped similar nodes together to reduce variation and streamline production.
    • ✅ Detailed templates: For common angle types, we provided accurate templates to guide fabrication.
    • ✅ Visual fabrication aids: Clear drawings showing exact cuts, welds, and orientations for every node.

    The Result

    • ⚡ Faster fabrication times
    • 🎯 Improved accuracy and alignment
    • 🔁 Reduced rework and error rates
    • 🤝 Stronger collaboration between design and workshop teams

    Most importantly, the fabricators were able to work with confidence, knowing each node would come together exactly as intended.

    Taking Detailing to the Next Level

    This project reinforced one of TEK1’s core values: true excellence in detailing comes not just from precision—but from empathy. When we truly understand the needs of the people building the structure, we unlock practical, buildable solutions.

    The Great EMU in the Sky is more than a globe—it’s a powerful example of what happens when detailers and fabricators work together as one team.
