Comparison Table
SDS2
vertical specialistSteel detailing software producing material lists and CNC data from connection models.
Quantity structure tied to piece marks for member traceability across framing and detail drawings.
SDS2 focuses on structural steel estimating workflows where quantity precision depends on member scope and consistent labeling across framing and detail drawings. The software supports on-screen takeoff workflows on 2D PDFs and CAD inputs, then keeps quantities organized so estimates can be reviewed by system, floor, or member group. Export formats and templated layouts support recurring estimate packages when projects follow similar drawing structures. SDS2 is also used in workflows that compare revised drawings and rerun affected takeoff areas to keep quantities aligned with updates.
A key tradeoff is that SDS2 works best when drawing labeling and piece marks are usable, because member traceability drives how quantities map to the estimate. SDS2 fits situations where teams need repeatable takeoff structure across similar projects and want measured quantities to stay readable during estimating review. When drawings are inconsistent or piece-mark data is missing, takeoff can become more manual and reconciliation takes longer.
- +Member-focused takeoff workflow keeps quantities organized by steel scope
- +Piece-mark aware quantity structure supports traceable estimate review
- +CAD and PDF inputs support practical drawing-to-quantity workflows
- +Revision-oriented takeoff reruns reduce rework on updated drawing sets
- –Best results depend on piece-mark quality in the source documents
- –Advanced configuration choices can add setup time on new project templates

Best for: Fits when estimators need traceable steel quantity takeoff tied to piece marks.
CADS Steel
vertical specialistStructural steel detailing and analysis software producing material schedules.
On-screen steel takeoff workflow that converts measured members into structured estimate quantities for fabrication handoff.
Estimators using CADS Steel typically need repeatable member takeoff for framing plans and detail sheets, then structured quantity output that matches shop and erection planning. The tool emphasizes takeoff accuracy through on-screen selection and dimensioning, then carries those results into estimation deliverables. This approach fits teams that already standardize drawing sets and want less rework between revisions.
A tradeoff is that automation depth depends on how well the input set aligns to the expected geometry and drawing presentation, since not every drawing style maps cleanly to steel takeoff objects. CADS Steel fits well when a team frequently estimates similar structural scopes and needs consistent tonnage-style reporting across repeated projects. It is less ideal for one-off experimental workflows that require deep data exchange with BIM authoring tools beyond import and export.
- +Steel-focused on-screen member takeoff workflow for consistent quantity outputs
- +Structured material reporting designed around fabrication and estimating needs
- +Works efficiently on standardized drawing sets with repeatable estimation steps
- +Supports revision-driven remeasuring without rebuilding the takeoff from scratch

It also supports export of takeoff results into downstream estimating environments, so quantity data can flow into bills of materials and material lists used for estimate documents.
A tradeoff appears in governance and throughput when teams rely on complex detailing standards across many projects. Maintaining consistent piece mark rules, connection labeling, and view discipline requires configuration work and discipline across estimators and detailers. Advance Steel fits best when estimating depends on the same authoring dataset that produces shop drawings and erection drawings, not when the inputs are only scanned 2D PDFs with no modeling backbone.
- +Member and connection quantities derive from detailing objects, not manual measurements
- +Piece mark based quantities reduce rework between detailing and estimating
- +CAD and model imports support estimates from existing engineering deliverables
- +Revision-driven quantity updates reduce discrepancy between drawings and takeoff

How to Choose the Right Structural Steel Takeoff Software
Structural steel takeoff software is where estimators turn member scope on framing and detail drawings into structured quantities that can roll into estimate-ready line items for fabrication. This buyer’s guide covers SDS2, CADS Steel, DESTINI Estimator, Tekla, and eight additional tools that support different markup-to-quantity workflows for steel estimating.
The selection focus is integration depth and automation surface, because member and connection takeoff quality depends on how each tool extracts and preserves piece-level identifiers from the drawings or detailing data. The guide also weighs governance controls such as auditability and permissions when tools expose automation behavior outside manual markup.
Structural Steel Takeoff Software that converts member and piece marks into estimate-ready quantities
