SDS2
enterpriseSteel detailing and connection design software used for fabrication-ready structural models.
Change-driven detailing that keeps member schedules and drawing views synchronized after framing edits.
SDS2 supports end-to-end structural detailing for metal buildings by driving member geometry from framing definitions and then propagating changes into schedules and drawings. The workflow fits teams that already use a standards-driven design basis and want consistent output for shop sets and erection planning. The tool’s exchange story is especially relevant when Tekla-compatible CNC output and drawing packages must align with fabrication constraints and naming conventions.
A tradeoff appears when projects require deep model-wide parametric edits beyond detailing scope, since SDS2 behavior is tuned for detailing automation and shop deliverables. SDS2 fits best when a detailing team must deliver repeatable framing and connection documentation across many similar buildings, while coordinating exchange files into downstream systems for fabrication scheduling.
- +Detailing-first framing workflow with change propagation to drawings
- +Fabrication-oriented member and assembly documentation
- +Tekla-compatible exchange paths for CNC-ready downstream work
- +Repeatable output conventions for consistent shop sets
- –Less suited to freeform BIM authoring and broad model edits
- –Requires strict framing definition discipline to avoid rework
- –Automation depth can slow one-off experiments outside detailing scope
- –External model coordination depends on correct data handoff formats

Best for: Fits when metal building detailing teams need repeatable framing documentation and shop-ready outputs.
Tekla PowerFab
enterpriseFabrication management software for steel detailers and fabricators with estimating, inventory, and production control.
Fabrication database driven outputs that generate drawing and CNC-ready manufacturing documentation from the same model.
Metal building projects benefit from Tekla PowerFab when detailing needs to stay consistent across framing, connections, and fabrication outputs that shop-floor teams can use. Drawing generation can be automated from the model, which reduces manual rework when design edits propagate through detailing. Production-centric workflows are the focus, including configuration of production document sets and standardization of common member and connection content.
A tradeoff appears when organizations need fast iteration without investing in standards for templates, naming conventions, and output configuration. Tekla PowerFab fits best when a fabricator already runs a Tekla-based modeling and fabrication documentation process and can enforce model authoring rules across the detailing team. It is less ideal when the fabrication shop expects a purely spreadsheet-based or bid-only workflow with minimal model governance.
- +Model-driven fabrication outputs reduce drawing-to-shop mismatches
- +CNC-ready detailing outputs support direct manufacturing handoff
- +Automated drawing production ties documentation to model objects
- +Production-oriented configuration supports repeatable project standards

ProNest
SMBCAD CAM nesting software for plate and sheet cutting used in steel fabrication shops.
Rule-based CNC nesting tied to job part sets, with constrained optimization that stays consistent across reruns.
ProNest is built around nesting jobs that combine part shapes, steel sheet or plate definitions, and cut constraints into optimized production runs. It supports lead-in and lead-out handling, kerf and toolpath style parameters, and generation of cut-ready output for CNC. This workflow fits metal building detailing where framing members and trim pieces must be nested with consistent cut rules and repeatable documentation. It also aligns with structural detail review cycles because nests can be rerun after changes to parts or quantities without rebuilding the entire process.
A key tradeoff is that ProNest depth is strongest for cutting and nesting rather than full structural analysis or framing design logic. Teams that rely on deep portal frame analysis, full AISI S100 member design, or moment connection detailing need those handled elsewhere, then passed as geometry and quantities. ProNest fits best when detailing outputs already exist and the priority is reliable nesting optimization and cut output consistency for fabrication.
- +Strong nesting optimization parameters for repeatable fabrication runs
- +CNC-ready output generation reduces manual cut-file cleanup
- +Material utilization controls support trim and small-part efficiency work
- +Workflow supports reruns when geometry or quantities change

Metal buildings software for PEMB and portal frame detailing, analysis-linked documentation, and fabrication-ready outputs
Metal buildings software connects structural modeling, framing detailing, and documentation outputs so teams can issue repeatable member schedules and shop drawing sets for metal building projects. SDS2 emphasizes change-driven detailing that keeps member schedules and drawing views synchronized after framing edits, which targets revision control inside the detailing workflow.
Tekla PowerFab treats the model as the authoritative fabrication database so the same model drives drawing and CNC-ready manufacturing documentation under controlled standards. Other tools in this guide shift that control surface toward CNC nesting in ProNest, erection and fabrication deliverables tied to PEMB workflow in ROMAC, or connection calculations generated from imported framing models in IDEA StatiCa.
Choose by the control surface that owns change: detailing, fabrication database, nesting, or analysis
Different metal building workflows assign authority to different stages. SDS2 and FRAMECAD Structure keep detail-level change control inside a framing and detailing workflow, while Tekla PowerFab assigns authority to a fabrication database that drives drawings and CNC documentation.
Pick the authority layer for revisions
Select SDS2 when the revision control need is synchronization between member schedules and drawing views after framing edits. Select Tekla PowerFab when the revision control need is that the model behaves as the fabrication-authoritative database for drawings and CNC-ready manufacturing documentation.
Align CNC control with the output style
Select ProNest when cut planning needs consistent, rule-based CNC nesting tied to job part sets and repeatable optimization parameters. Select Tekla PowerFab when CNC documentation should come from the same authoritative model that drives fabrication drawings.
Match PEMB deliverables to the workflow depth
Select ROMAC when PEMB framing decisions should directly generate erection and fabrication deliverables for recurring variants. Select FRAMECAD Structure when framing-first rule configurations must propagate consistent member and connection changes across standardized bays.
Choose an analysis-to-sizing loop or a detailing-first automation focus
Select RISA-3D when portal frame analysis-to-member sizing iteration needs to occur inside one portal frame analysis workflow context. Select SkyCiv Structural 3D when a single 3D structural model should support analysis iteration and draw-ready member layouts with lighter automation for estimating and panelization planning.
If the team already has a framing model, set connection workflow expectations
Select IDEA StatiCa when connection design output must be driven by imported framing models with clear input-to-result traceability and repeatable joint workflows. Select SDS2 instead when change-driven detailing synchronization across schedules and drawings is the primary revision driver for the team.
Use configuration rule outputs when projects repeat patterns
Select STACK when project configuration should drive output rules that keep member and connection data consistent across drawing and fabrication exports. Select ROMAC when the deliverables and automation must attach directly to PEMB framing workflow decisions for recurring building variants.
Common failure modes in metal buildings software selection
Many metal building teams choose based on which tool looks best at the start of a workflow, then hit rework when revisions affect downstream deliverables. The missteps below map to specific capability gaps shown by how each tool frames automation and output ownership.
Buying a fabrication-output tool for a detailing-first revision control need
Tekla PowerFab can reduce drawing-to-shop mismatches through model-driven fabrication outputs, but SDS2’s change-driven detailing targets schedule and drawing synchronization after framing edits. Teams that rely on detailing change propagation should center SDS2 or FRAMECAD Structure rather than expecting fabrication outputs to carry revision control alone.
Assuming CNC nesting tools will replace structural framing checks
ProNest focuses on rule-based CNC nesting tied to job part sets, and it has limited structural framing analysis compared with model-centric tools. CNC cut planning needs accurate machine and material definitions to avoid cleanup and rework.
Expecting PEMB deliverable automation to work outside a constrained framing workflow
ROMAC provides automation tied to PEMB framing decisions and recurring variants, and its flexibility drops for nonstandard detailing beyond that workflow. FRAMECAD Structure also depends on framing rule configurations and vendor export formats for extensibility.
Treating connection design software as end-to-end modeling for metal building structures
IDEA StatiCa delivers connection design checks with traceability from imported framing models, but it is less suited to end-to-end PEMB or portal frame authoring. Teams needing full framing documentation and fabrication handoff should pair connection calculations with a framing or fabrication-authoritative workflow such as SDS2 or Tekla PowerFab.
Choosing configuration-driven exports without allowing for advanced detailing depth
STACK can keep member and connection data consistent via project configuration output rules, but structural detailing depth can lag parametric authoring in Tekla and Revit. Complex custom components may require external drafting steps, which increases the work outside the configured export path.
