Definition
In Tekla Structures, Clash Check operates as a central design principle. An analytical tool sweeping 3D structural models to identify physical overlaps between steel, concrete, rebar, and anchor bolts.
Why it matters
Proficiency with Clash Check is critical for achieving industry-standard documentation quality. Catching structural conflicts before construction starts, preventing expensive field modifications.
Common pitfalls
- Setting clash tolerances too low, generating thousands of false positive warnings.
- Ignoring clashes in non-structural elements.
Tekla Structures Ecosystem Context
This concept is a core structural element of the Tekla Structures drafting and engineering environment developed by Trimble. Trimble's premier structural BIM authoring tool, delivering detailed LOD 500 models for steel and concrete.
Relevant Tekla Structures FAQs
❓ What is the recommended practice for Tekla Structures Steel Detailing?
Use Measurement tools to inspect distances, angles, areas, and volumes. Access mass properties (volume, center of mass, moments of inertia) from the Properties panel—assign material density for accurate weight calculation. Use section analysis for cross-sectional properties. Export measurements to spreadsheets for documentation.
❓ What is the recommended practice for Tekla Structures Cast-in-Place Concrete?
Model steel members from standard section profiles (W, HSS, L, C) with proper orientation and end conditions. Apply connections (bolted, welded) from the connection library—automatically generates plates, bolts, and welds. Number parts using Assembly/Part numbering series. Generate shop drawings with automatic dimensioning.
❓ What is the recommended practice for Tekla Structures Rebar Detailing?
Model cast-in-place concrete by defining pour units (slabs, walls, columns, beams) with proper geometry and material grades. Add construction joints and pour sequences. Embed rebar and post-tensioning within pour elements. Generate formwork drawings showing dimensions, elevations, and embedded item locations.
