Definition
In Tekla Structures, User-Defined Attributes forms an integral part of the design workflow. User-configurable fields (UDAs) hosting asset numbers, manufacturer codes, and structural ratings on 3D geometry.
Why it matters
The quality of final deliverables often traces back to how well User-Defined Attributes was handled in early phases. Ensures structural models act as rich BIM databases, automatically exporting data to client PLM and ERP systems.
Common pitfalls
- Attaching UDAs with duplicate identifier keys.
- Mismatched data types.
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.
