Common Mistakes to Avoid
The most common failures happen when buyers choose tools that do not keep detailing, connections, and coordination synchronized under day-to-day changes.
Buying for 3D modeling only and underestimating detailing synchronization
Teams that select a tool mainly for 3D geometry often face drawing rework when updates do not propagate cleanly. Tekla Structures and Advance Steel are built around model-driven detailing so changes in steel members can directly affect drawings.
Ignoring connection modeling quality until fabrication issues appear
Late discovery of connection representation problems forces manual corrections and slows release cycles. Tekla Structures emphasizes connection-aware steel modeling, while Advance Steel keeps connection detailing aligned with its steel modeling and drawing workflow.
Treating structural verification as a separate world from the model
When verification outputs do not track model edits, geometry and design checks can drift out of sync. SDS/2 supports engineering-centric steel design verification, and Tekla Structures supports workflows where detailing and coordination can reflect ongoing model changes.
Selecting a tool that does not match the team’s repeatability standards
Teams that lack automation for templates and rules often lose time to repetitive drafting and inconsistent output. Tekla Structures and Advance Steel both support repeatable steel detailing patterns that reduce manual rework.
