Tekla vs. SDS2 vs. Revit for Structural Steel Detailing: Which Is Best for Your Project?

Structural steel projects increasingly depend on digital modeling and coordinated construction documentation. A modern detailing workflow may include 3D modeling, connection development, fabrication drawings, erection drawings, material information, clash coordination and BIM deliverables.

Because software platforms approach these requirements differently, selecting the right tool requires more than comparing feature lists.

This guide compares Tekla Structures, SDS2 and Revit from the perspective of structural steel detailing and project delivery.

What Is Structural Steel Detailing Software?

Structural steel detailing software is used to develop detailed digital representations of steel structures and generate information required for fabrication, erection and construction coordination.

Depending on the platform and project workflow, this can include:

• 3D structural steel modeling
• Steel member detailing
• Connection modeling
• Shop drawing production
• Erection drawing production
• Material lists
• Bolt information
• Fabrication information
• BIM coordination
• Model-based documentation

7Solution India currently provides structural steel detailing and BIM-related services using modern CAD and BIM workflows for global projects.

Tekla Structures for Steel Detailing

Tekla Structures is widely associated with detailed structural steel modeling and fabrication-oriented workflows.

It is particularly useful when a project requires highly detailed steel models, connections, fabrication information and coordinated shop and erection documentation.

Strengths of Tekla

• Detailed structural steel modeling
• Complex connection modeling
• Fabrication-oriented workflows
• Detailed shop drawing production
• Erection documentation
• Material and assembly information
• Complex steel geometry
• Detailed model-based coordination

For fabrication-intensive structural steel projects, Tekla can be particularly effective when the 3D model is expected to contain detailed information about individual fabricated components.

SDS2 for Structural Steel Detailing

SDS2 is another specialized platform used for structural steel modeling, detailing and fabrication workflows.

Its workflow is strongly oriented toward structural steel detailing, including steel members, connections, fabrication information and construction documentation.

Strengths of SDS2

• Structural steel modeling
• Automated connection workflows
• Fabrication-oriented detailing
• Steel shop drawing production
• Erection documentation
• Material and piece information
• Model-based coordination

For steel fabricators and detailers whose projects are heavily focused on structural steel fabrication, a dedicated steel detailing platform can provide advantages over a general-purpose BIM workflow.

Revit for Structural BIM

Autodesk Revit approaches the problem from a broader BIM perspective.

Rather than focusing exclusively on fabrication-level steel detailing, Revit is widely used for multidisciplinary building information modeling involving architectural, structural and MEP disciplines.

This makes Revit particularly useful when structural steel information needs to participate in a larger BIM coordination environment.

Strengths of Revit

• Multidisciplinary BIM coordination
• Structural modeling
• Architectural coordination
• MEP coordination
• Construction documentation
• Parametric modeling
• Family-based modeling
• BIM data management

7Solution India's Structural BIM service includes structural BIM modeling, BIM-based coordination, construction documentation, Revit family creation, as-built modeling and point-cloud-to-BIM workflows. :contentReference[oaicite:4]{index=4}

Tekla vs SDS2 vs Revit: Quick Comparison

Tekla vs SDS2: Which Is Better?

Tekla and SDS2 are both capable of supporting detailed structural steel workflows. The better choice depends on the project environment, fabrication requirements, company standards and team expertise.

A fabricator focused heavily on steel production may prioritize fabrication workflow, connection development, drawing automation and downstream manufacturing information.

For complex projects, the decision should also consider the team's existing experience and the requirements of the fabricator and erection contractor.

Tekla vs Revit: What Is the Difference?

Tekla and Revit can both represent structural steel in 3D, but their typical project roles can be different.

Tekla is often selected for highly detailed steel modeling and fabrication-oriented workflows, while Revit is commonly used as part of a broader multidisciplinary BIM environment.

For a project requiring extensive architectural, structural and MEP coordination, Revit can be particularly useful.

For a project where fabrication-level structural steel information is the primary requirement, a specialized detailing platform may be more appropriate.

SDS2 vs Revit for Steel Projects

The comparison between SDS2 and Revit follows a similar principle.

SDS2 is oriented toward structural steel detailing and fabrication workflows, while Revit is designed around broader BIM coordination and information modeling.

The choice should therefore depend on the final deliverables rather than simply the number of features offered by each platform.

Which Software Is Best for Steel Fabricators?

Steel fabricators generally require more than a visual structural model.

They need detailed information that can support:

• Material procurement
• Cutting
• Drilling
• Welding
• Assembly
• Quality control
• Transportation
• Erection

For highly fabrication-oriented projects, dedicated steel detailing platforms such as Tekla or SDS2 can be strong options.

However, the final decision should consider the fabricator's existing software ecosystem, project requirements, detailing standards and downstream fabrication processes.

Which Software Is Best for BIM Coordination?

When multidisciplinary BIM coordination is the primary objective, Revit can be highly effective because structural information can participate in a broader building model alongside architecture and MEP systems.

This can be particularly valuable for commercial buildings, healthcare facilities, institutional projects and other multidisciplinary construction environments.

Does the Software Choice Affect Shop Drawing Quality?

Software is important, but it is not the only factor that determines drawing quality.

The experience of the detailing team, project standards, modeling discipline, checking procedures and understanding of fabrication requirements are equally important.

A highly capable software platform cannot compensate for poor modeling practices or inadequate quality control.

Professional structural shop drawing services should therefore combine appropriate software with experienced detailers and systematic QA/QC.

What Should You Consider Before Choosing Detailing Software?

Before selecting a platform, project teams should evaluate several factors.

• Project type
• Structural complexity
• Fabrication requirements
• Required deliverables
• Connection complexity
• BIM coordination requirements
• Client standards
• Fabricator standards
• Existing software environment
• Team experience
• Interoperability requirements
• Project schedule

Software Is Only One Part of the Detailing Workflow

It is easy to focus on software comparisons, but successful structural steel detailing depends on the complete workflow.

A reliable process typically includes:

1. Design drawing review
2. Project specification review
3. 3D model development
4. Connection development
5. Model coordination
6. Shop drawing production
7. Erection drawing production
8. Material and fabrication information
9. Internal QA/QC
10. Client review and revisions

The software supports this process; experienced professionals make the process effective.

Can One Project Use More Than One Platform?

Yes. Many complex construction projects involve multiple software platforms throughout the design, coordination and fabrication lifecycle.

For example, a project may use Revit for multidisciplinary BIM coordination and a specialized steel detailing platform for fabrication-level structural steel documentation.

The key requirement is maintaining accurate information exchange and model coordination between platforms.

Final Verdict: Tekla, SDS2 or Revit?

Conclusion

Tekla Structures, SDS2 and Revit are all powerful platforms, but they are optimized for different project workflows.

Tekla and SDS2 are particularly strong choices when structural steel detailing and fabrication are central to the project. Revit becomes especially valuable when structural steel must participate in a broader multidisciplinary BIM environment.

The best software is therefore not necessarily the one with the longest feature list. It is the platform—or combination of platforms—that best matches the project's structural complexity, fabrication requirements, BIM coordination needs and final deliverables.

Ultimately, software should support an experienced detailing team and a disciplined QA/QC process. That combination is what turns a digital model into reliable construction information.
