Structural Drawing

Knowing how to read structural drawings is an essential skill for structural engineers, architects, site managers, and construction professionals across Australia. These drawings — prepared to AS/NZS 1100 (Technical Drawing Standard) — contain all the information needed to construct a building’s structural frame safely and to specification.

This guide walks you through every element of a structural drawing set, from the title block and legend through to reinforcement schedules and cross-referencing with architectural and MEP drawings.

What Are Structural Drawings?

Structural drawings are engineering documents that define the load-bearing elements of a structure — foundations, columns, beams, slabs, walls, and connections. Unlike architectural drawings (which show what a building looks like), structural drawings show how it stands up. In Australia, structural drawings must comply with:

  • AS/NZS 1100 — Technical drawing conventions
  • AS 3600 — Concrete structures
  • AS 4100 — Steel structures
  • AS 1170 — Structural loading (dead, live, wind, seismic)
  • National Construction Code (NCC)

Step 1: Start with the Title Block

Always begin at the title block — usually in the bottom-right corner of each sheet. It contains:

  • Project name and address
  • Drawing title and number (e.g. “S-101 Foundation Plan”)
  • Scale (e.g. 1:100, 1:50)
  • Revision number and date
  • Engineer’s name and stamp — required for NCC-regulated work
  • Drawing date and issue status (IFC, IFT, IFA)

Check the revision status first — always work from the latest “Issued for Construction” (IFC) revision.

Step 2: Read the Legend and General Notes

Before reading any geometry, review the legend and general notes sheet (usually sheet S-001). These define:

  • Abbreviations (e.g. RHS = Rectangular Hollow Section, SHS = Square Hollow Section, CHS = Circular Hollow Section, UB = Universal Beam, UC = Universal Column)
  • Material grades (e.g. Grade 300 steel, 32 MPa concrete, N12 rebar)
  • Cover requirements for concrete reinforcement
  • Weld symbols (per AS/NZS 2980)
  • Bolt grades and connection standards

Step 3: Identify the Drawing Type

A structural drawing set includes several drawing types — each shows something different:

Drawing TypeWhat It ShowsCommon Scale
Foundation PlanFooting locations, pile caps, slab-on-ground1:100 or 1:200
Floor Framing PlanBeam and slab layout at each level1:100
Roof Framing PlanRoof beams, rafters, purlins, bracing1:100
ElevationSide view — heights, bracing, cladding rails1:100 or 1:50
SectionCut-through view of structural assembly1:50 or 1:20
DetailEnlarged view of connections, reinforcement, joints1:10 or 1:5
Reinforcement ScheduleBar marks, sizes, lengths, bending shapesN/A (tabular)

Step 4: Identify Structural Elements

  1. Foundations — Strip footings, pad footings, raft slabs, or piles. Shown with heavy lines and hatching.
  2. Columns — Vertical load-carrying elements. On plan views, shown as solid squares or circles with a grid reference (e.g. C1, C2).
  3. Beams — Horizontal elements. Shown as dashed lines on floor plans above, with section marks calling up beam schedule entries (e.g. B1 = 310UB46.2).
  4. Slabs — Shown with thickness, top/bottom reinforcement, and drop panels where applicable.
  5. Walls — Structural (load-bearing) walls shown in solid fill; non-structural shown with lighter lines.
  6. Bracing — Diagonal elements (steel flats, RHS, rods) shown with crossing lines on elevations.

Step 5: Read Grid Lines and Dimensions

Grid lines organise all structural elements. In Australia, grids follow AS/NZS 1100 conventions:

  • Letters (A, B, C…) for one axis (usually north-south)
  • Numbers (1, 2, 3…) for the other axis (usually east-west)
  • Grid intersections locate every column (e.g. column at B3)
  • Grid dimensions run between grid lines — these are structural centres, not finished face dimensions

Step 6: Read Reinforcement Details (Concrete Structures)

Reinforcement is specified using bar marks and a reinforcement schedule. In Australia (AS 3600):

  • N bars = deformed (ribbed) bars — standard structural reinforcement
  • R bars = plain round bars — ties, fitments
  • L bars = low ductility (less common in primary structure)
  • Bar notation: N16 @ 200 B1 = 16mm deformed bar at 200mm centres, bottom layer, first direction
  • Cover is specified separately — typically 20–65mm depending on exposure class

The reinforcement schedule lists every bar mark with its shape code (per AS 3600 Appendix D), diameter, length, and quantity.

Step 7: Read Steel Connection Details

Steel connection details show how members join. Look for:

  • Weld symbols — fillet welds (triangle), full penetration welds, plug welds. Weld size specified on symbol.
  • Bolt groups — number of bolts, grade (e.g. Grade 8.8), diameter (M20, M24), and bolt pattern
  • End plates and cleats — plate thickness, grade (e.g. 250, 350)
  • Galvanising note — required for external or corrosive environments

Step 8: Cross-Reference with Other Drawing Sets

Structural drawings never stand alone. Always cross-reference:

  • Architectural drawings — wall positions, openings, setouts. Structural elements must fit within architectural envelope.
  • Civil drawings — site levels, stormwater, retaining structures
  • MEP/Services drawings — penetrations through slabs and beams, structural reinforcement around openings
  • Geotechnical report — foundation bearing capacity, settlement, ground type (AS 1726)

Step 9: Check Revisions

Revisions are shown with revision clouds or triangle revision markers. The revision table in the title block records every change. Before using any drawing on site:

  • Check you have the current revision (compare revision number and date)
  • Read all revision notes — even small changes to concrete cover or bar spacing matter

What is the difference between architectural and structural drawings?

Architectural drawings focus on the design, aesthetics, and spatial layout of a building — what it looks like. Structural drawings focus on the load-bearing system — how the building stands up. In Australia, structural drawings are prepared by a registered structural engineer to AS/NZS 1100 and referenced standards (AS 3600, AS 4100, AS 1170), while architectural drawings are prepared by a registered architect. Both sets must coordinate: structural elements (columns, walls, beams) must fit within the architectural design.

What Australian standard covers structural drawing conventions?

AS/NZS 1100 — Technical Drawing is the primary standard governing structural drawing conventions in Australia. It covers drawing layout, line types, symbols, dimensioning, and annotation conventions. Reinforcement detailing follows AS 3600 Appendix D. Steel connection detailing follows AS 4100. Engineers and drafters preparing structural drawings in Australia must comply with these standards and the National Construction Code.

What does N16@200 mean on a structural drawing?

N16@200 means 16mm diameter deformed (N-grade) reinforcing bar placed at 200mm centres. In AS 3600 notation, ‘N’ indicates deformed high-strength bar (fy = 500 MPa), ’16’ is the bar diameter in millimetres, and ‘@200’ means the bars are spaced 200mm apart. You’ll also see a suffix like B1 (bottom, first direction) or T2 (top, second direction) to indicate bar layer and orientation within the slab or beam.

How do I find the current revision of a structural drawing?

Check the title block — usually in the bottom-right corner of each sheet. The revision table lists every revision with a letter (A, B, C…), date, description, and engineer’s initials. Always confirm the issue status: IFC (Issued for Construction) is the only status suitable for construction work. IFT (Issued for Tender) and IFA (Issued for Approval) drawings are not for construction use. On digital sets, check the metadata and compare with the document register from your project manager.

Mechanical Drafting

The ability to read mechanical drawings — also called engineering drawings or technical drawings — is a foundational skill for mechanical engineers, machinists, fitters, welders, and anyone involved in manufacturing or fabrication. In Australia, mechanical drawings follow AS/NZS 1100 conventions with GD&T per AS 1101.101.

This guide explains every element of a mechanical drawing — from the title block and projection type through to tolerances, surface finish symbols, and GD&T — so you can confidently interpret any drawing you encounter on the job.

What Is a Mechanical Drawing?

A mechanical drawing is a technical document that fully defines a manufactured part or assembly. It communicates every dimension, tolerance, material specification, surface finish requirement, and manufacturing note needed to make the part — without ambiguity. A well-drawn mechanical drawing can be sent to any workshop in Australia and the part will come back exactly right.

Mechanical drawings typically include:

  • Orthographic views (front, top, side)
  • Section and detail views
  • Dimensions and tolerances
  • GD&T symbols
  • Surface finish callouts
  • Material and treatment specifications
  • A title block and revision history
  • A bill of materials (for assemblies)

Step 1: Read the Title Block First

The title block — bottom-right corner of every drawing sheet — contains everything you need to verify before reading geometry:

FieldWhat It Tells You
Part Name / Drawing TitleWhat the drawing depicts
Drawing NumberUnique reference ID for document control
RevisionCurrent revision letter (A, B, C…) — always use the latest
Scalee.g. 1:1, 1:2, 2:1 — ratio of drawn size to actual size
Materiale.g. 304 SS, 6061-T6 Aluminium, 1020 Steel, HDPE
Surface Treatmente.g. Anodise, Zinc Plate, Powder Coat, Passivate
General TolerancesDefault tolerances when not specified individually (e.g. ±0.1 linear, ±0.5°)
Projection SymbolFirst angle (ISO / AS) or third angle (US/ASME) — critical for reading views correctly
Drafter / Checker / ApprovedAccountability chain

Australia uses First Angle Projection (AS/NZS 1100). The projection symbol is a truncated cone — in first angle, the cone points left. In third angle (common in US drawings), the cone points right. Confusing the two means you’ll read the top view when you should read the bottom view.

Step 2: Understand the Views

Mechanical drawings use multiple 2D views to fully describe a 3D object:

View TypeDescriptionWhen Used
Front ViewPrimary view — the most descriptive face of the partAlways
Top ViewLooking straight down at the partMost parts
Side View (Left or Right)Looking from the left or rightWhen front + top don’t fully describe the part
Isometric View3D pictorial — for visualisation only, not dimensioningComplex parts, assembly aids
Section ViewCut through the part to show internal featuresHoles, bores, internal pockets
Detail ViewMagnified area with its own scale callout (e.g. “DETAIL A — 2:1”)Small features, thread details
Auxiliary ViewView projected from an angled surfaceAngled faces that aren’t captured in standard views

Step 3: Read Line Types

Every line type in a mechanical drawing means something specific (AS/NZS 1100):

Line TypeAppearanceMeaning
Visible outlineThick solid lineEdge visible in this view
Hidden lineThin dashed lineEdge behind the current view surface
Centre lineThin long-short-long dashAxis of symmetry, centre of holes/cylinders
Dimension lineThin solid with arrowheadsShows what is being measured
Extension lineThin solid projecting from featureExtends to meet dimension line
Leader lineThin line with arrowhead and notePoints to a feature with a note or callout
Section line (hatch)Thin diagonal lines at 45°Cut surface in section view
Phantom lineLong-short-short dashAlternate positions, adjacent parts, repeat features
Break lineIrregular freehand or straight with ZShows a portion is removed for space

Step 4: Read Dimensions

Dimensions are the core of any mechanical drawing. Australian mechanical drawings use millimetres (mm) as the default unit (the “mm” is often omitted once stated in the title block). Key rules:

  • Never scale the drawing — always use the stated dimensions
  • Dimensions without a tolerance apply the title block’s general tolerance
  • Chain dimensioning — dimensions in a chain; errors accumulate
  • Datum dimensioning — all dimensions from a common reference; no error accumulation
  • prefix = diameter (cylindrical features)
  • R prefix = radius
  • prefix = square feature
  • SR = spherical radius, S⌀ = spherical diameter

Step 5: Read Tolerances

Tolerances define how much a dimension can vary and still be acceptable. There are two main systems:

Linear Tolerances

  • Bilateral: 25.00 ±0.05 = acceptable range 24.95–25.05
  • Unilateral: 25.00 +0.10/−0.00 = acceptable range 25.00–25.10
  • Limits: 24.95 / 25.10 (max and min written directly)

Geometric Dimensioning & Tolerancing (GD&T)

GD&T uses feature control frames to specify form, orientation, location, and runout. In Australia, GD&T follows AS 1101.101 (equivalent to ISO 1101). Common symbols:

SymbolCharacteristicApplies To
⏤ (straight line)StraightnessAxis or surface
FlatnessSurface
Circularity (roundness)Cross section
CylindricityFull cylinder
ParallelismSurface or axis
PerpendicularitySurface or axis
AngularitySurface or axis
Position (true position)Hole or feature location
Concentricity / coaxialityAxis to datum
↗ (circular arrow)Circular runoutRotating surfaces

A feature control frame reads left to right: geometric characteristic symbol | tolerance value | datum references. For example: ⌖ | ⌀0.05 | A | B means “true position within a diameter 0.05mm zone, relative to datums A and B.”

Step 6: Read Surface Finish Symbols

Surface finish symbols (per AS/NZS 1100.303) specify the required surface roughness. The value given is the Ra (arithmetic mean roughness) in micrometres (µm):

  • Ra 0.8 µm — fine machined (ground, honed)
  • Ra 1.6 µm — standard machined finish
  • Ra 3.2 µm — general machined
  • Ra 6.3 µm — rough machined
  • The “tick” symbol (√) with a horizontal bar means the surface must be machined; with a circle in the tick means no machining allowed (as-cast/as-forged)

Step 7: Read Thread Callouts

Threads are called out with a standard notation. In Australia, most mechanical threads are ISO metric per AS 1275:

  • M12 × 1.75 — 6H = Metric thread, 12mm nominal diameter, 1.75mm pitch, 6H tolerance class (internal thread)
  • M12 × 1.75 — 6g = External thread (lowercase = external, uppercase = internal)
  • M8 THRU = M8 thread through the full thickness
  • M8 × 20 DEEP = M8 thread 20mm deep (blind hole)

Step 8: Read Welding Symbols (if applicable)

Welded assemblies include welding symbols per AS 2812 / AS/NZS 2980. The reference line runs horizontally. The arrow points to the joint. Symbols below the line indicate the arrow side; above the line indicates the other side:

  • Fillet weld — right triangle symbol; size given as leg length (e.g. 6 ←▷)
  • Full penetration butt weld — single or double bevel/V symbols
  • All-around weld — circle at the arrow/reference line junction
  • Field weld — flag at the junction

Step 9: Read Assembly Drawings

Assembly drawings show how individual parts fit together. Key features:

  • Item balloons — circles with item numbers pointing to each part
  • Bill of Materials (BOM) — table listing item number, part number, description, material, quantity
  • Exploded view — parts shown separated along their assembly axes
  • Assembly dimensions — overall envelope dimensions and critical fit dimensions
  • Individual part drawings are referenced by part number — read both together

What is the difference between first angle and third angle projection?

First angle projection (used in Australia and Europe per AS/NZS 1100 and ISO) places views as if the object has been rolled away from the viewer — the right side view appears on the left, the top view appears below the front view. Third angle projection (used in the USA per ASME Y14.5) places views as if the object rolls towards the viewer — the right side view appears on the right, the top view appears above the front view. Always check the projection symbol in the title block. Misidentifying the projection type will cause you to read the wrong view.

What does ±0.1 mean on a mechanical drawing?

±0.1 is a bilateral tolerance. It means the dimension can be 0.1mm larger or 0.1mm smaller than the stated value. For example, if a hole is dimensioned as ⌀20.00 ±0.1, the acceptable range is ⌀19.90mm to ⌀20.10mm. This is different from a unilateral tolerance like +0.2/−0.0, which would mean 20.00mm to 20.20mm. The general tolerance in the title block applies to all dimensions that don’t have an individual tolerance callout.

What does Ra 1.6 mean on a mechanical drawing?

Ra 1.6 specifies a surface roughness of 1.6 micrometres arithmetic mean roughness (Ra). This is a standard machined finish achieved by turning, milling, or grinding. Smoother surfaces have lower Ra values (e.g. Ra 0.4 for ground or lapped surfaces). Rougher surfaces have higher values (e.g. Ra 6.3 for a rough milled surface). The surface finish symbol in Australia follows AS/NZS 1100.303. The value is always in micrometres (µm).

How do I read a feature control frame in GD&T?

A feature control frame is read left to right in three compartments: (1) the geometric characteristic symbol (e.g. ⌖ for position, ⊥ for perpendicularity), (2) the tolerance value — often preceded by ⌀ if it’s a diameter zone — e.g. ⌀0.05, and (3) the datum references (e.g. A, B, C). So ⌖ | ⌀0.05 | A | B means: the true position of this feature must fall within a cylindrical tolerance zone of diameter 0.05mm, located relative to datums A and B. In Australia, GD&T follows AS 1101.101, equivalent to ISO 1101.

AutoCAD software tools are known worldwide for providing 2D and 3D design features, documentation and collaboration processes for any design task. Furthermore, the software tools enable designers to share their work with one another by using TrustedDWG® technology.

The purpose of this article is to:

  • Look briefly at the new features present in the newest AutoCAD release,
  • Identify significant changes between the newest and previous software releases,
  • Determine the impact of Visual Accuracy and other major benefits which the newest release of AutoCAD provides.

What New Features are Present in the Autocad 2016 Newest Release?

  • With Smart Dimensioning, appropriate measurements are created automatically, based on the drawing context. Bypassing the cursor over a selected object, the designer gets a preview of the dimension before creating it. For example, by selecting and holding a cursor over the cross-section of a duct, modified inner and outer diameters can be previewed before they are created.
  • The Coordination Model makes it possible to attach and view Navisworks® and BIM 360 Glue models directly inside AutoCAD. This makes it possible to import architectural design data created by Navisworks or to import a building design project into AutoCAD. The ability to merge design data between AutoCAD and BIM models provides the framework for KBE (Knowledge-Based Engineering), and for maintaining concurrency and synergy between product design teams.
  • The Enhanced PDFs feature makes it possible to quickly create smarter, smaller and powerful PDF files which are text searchable.
  • The Visual Experience feature enables the engineer to see design details with certain visual enhancements such as Line Fading. True curves are used instead of line segments for image rendering. For example, a circle is created as a continuous curve rather than several straight line segments. Instead of performing several Undo operations, a Command preview enables the designer to see the results of a command before committing to it. Large selection sets are easier to copy or move.
  • The designer is able to customise his/her design environment and systems settings and to prevent unwanted changes from being made.

In What Areas Are There Significant Software Changes?

The following list highlights significant software changes between AutoCAD 2016 (newest release) and previous versions of AutoCAD.

In terms of User Interaction, AutoCAD 2016 provides:

  • The Help Find tool, Improved graphics, Command preview, and resizable viewports are improved in AutoCAD 2016 and AutoCAD 2015.
  • The Move/Copy feature has been boosted in AutoCAD 2016 over previous versions.

In terms of the Design Interface, AutoCAD 2016 provides:

  • Center of polygon object snap
  • High-fidelity lines and curves
  • Coordination model
  • Point cloud dynamic UCS (Unified Computing System) and geometry extraction

In terms of Documentation, AutoCAD 2016 provides:

  • Revision Cloud enhancements
  • Smart dimensioning
  • PDF enhancements and optimised file output
  • The searchable text and hyperlink support in exported PDFs
  • Simplified, powerful rendering
  • Overriding of Xref (External Reference File in a cloud system) layer properties

What Major Benefits does the Newest Release of Autocad Provide?

The previous section of this article mentioned significant software improvements between AutoCAD 2016 and previous versions. It may be informative to look more closely at what some of these software improvements mean.

Coordination Models enable design data from Navisworks and BIM360 models (NWC, NWD) to be attached directly into AutoCAD. This feature supports the collaborative and synergistic product development model available in BIM. This feature also supports KBE (Knowledge-Based Engineering) and Expert Systems, which is important for retaining in-house design expertise and knowledge.

Smart dimensioning speeds up design work, because many “Undo” commands can be avoided by using the Preview feature in the new software release. Instead of establishing a dimension for an object and undoing it in order to create a new dimension, the object can be selected with the cursor, previewed or “hovered over”, before establishing the dimension.

The “Snap to geometric centre” feature enables the designer to snap to the centre of closed regular or irregular polylines.

Improvements to the drawing canvas dramatically improve the visual accuracy seen on screen. Although the human visual system can interpret a series of jagged line segments as an integrated smooth curve, it is much better to represent smooth curves and arcs with true curves. Doing so creates graphic objects with true fidelity and visual acuity, and creates a much better viewing experience.

A number of preset rendering options have been introduced, such as “Coffee-Break Quality”. Image-based lighting has been introduced to improve visual rendering.

The “UI finder” utility makes it easy to find just about anything in AutoCAD’s UI, including entries on the application menu and the status bar.

PDF enhancements create smaller files (about half the size of previous PDFs). The PDFs are generated quicker, and they permit text search and selection, even with multibyte and Unicode characters. Furthermore, SHX fonts (which have the source text added as a comment) are supported. Hyperlinks are maintained, whether they are embedded URLs or links between drawing content.

The System Variable Monitor (Sysvar) protects the design engineer from having his established or preset environment from being altered. In a multi-tasking environment, it is likely that an impolite application may alter sysvar settings, but fail to reset them to their previous settings after the application has completed its tasks.

Conclusion

Although this article sounds as if it is focused on sales or marketing, its purpose is to keep the CAD engineer aware of improved software features (such as improved visual accuracy in AutoCAD 2016) which become available in new CAD software releases.

The CAD engineer works in a fast-paced environment in which technological progress should be expected. In order to stay current and not to become obsolete, it is necessary for the CAD engineer to be aware of improved capabilities in new software releases.
