Autodesk AutoCAD is a market leading computer aided design system widely adopted in different industries locally and internationally, especially the architectural, engineering, and construction (AEC) industries.
It is well-known for its mature, powerful, and comprehensive tools in producing and managing design and working drawings. It becomes a de facto standard CAD system in regional market and as a required knowledge for a number of disciplines especially the architectural discipline.

The assessment is conducted in 2 sessions:
| Duration: | Total 3.5 hours |
| Session 1: | MC / short questions - 30 minutes (software accessible) |
| Session 2: | 1 compulsory task-based practical exercise - 3 hours |
| Language: | English with Chinese annotation |
| Software: | English / Chinese Interface (must be specified before assessment starts) |
| Note: no internet access available during assessment |
The assessment requires candidate to interpret design sketch and prepare typical 2D drawings and 3D models in AutoCAD. Understanding fundamental concepts in using the computer aided design system and in-depth knowledge of commands are also expected.
- Understanding AutoCAD user interface: command prompt, pull-down menu, toolbar, pointing device, and viewports.
- Setting up drawing file: template, limits, and units
- Understanding various coordinate systems: world coordinate system (WCS), user coordinate system (UCS), Cartesian coordinate system, polar coordinate system, origin, absolute coordinate, and relative coordinate
- Constructing entities: point, line, ray, construction line, multiline, polyline, rectangle, polygon, arc, circle, ellipse, spline, donut, hatch, boundary, and region
- Using view and navigation functions: various zoom functions, pan, redraw, regeneration, aerial view, viewports settings, orthographic & isometric views, vpoint, 3dorbit, and named views
- Making selection: pickbox, select by window, crossing, window polygon, crossing polygon, fence, all, previous, last, undo, add, remove, and quick select
- Duplicating entities and defining blocks: copy, offset, divide, measure, rectangular array, polar array, 3D array, mirror, mirror 3D, defining block and attributes, write block, insert, and external reference
- Modifying entities: undo, erase, move,
rotate, rotate 3D, scale, stretch, extend, lengthen, trim, fillet, chamfer,
break, explode, pedit, change, chprop, properties, match properties,
and in-place editing
- Defining annotation and dimension entities: text, multiline text, symbols, stack, formatting character and paragraph, and defining and modifying dimension (eg. linear, aligned, ordinate, radius, diameter, angular, baseline, continue, leader, center mark, and tolerance)
- Using drawing assistance: snap, grid, orthographic mode, polar tracking, object snap (eg. endpoint, midpoint, nearest, intersection, apparent intersection, perpendicular, parallel, center, quadrant, tangent, node, insertion, extension), object snap tracking, and inquiry commands (eg. list, distance, and area)
- Managing drawing: layer, line weight, line
type, line color, line type scale, point style, text style, dimension
style, and managing files with AutoCAD Design Center and i-drop technology
- 3D modeling methods: construction of solid primitives (eg. box, sphere, cylinder, cone, wedge, and torus), extrude and revolve solid, Boolean operations (union, subtract, and intersect), slice, section, interference, and solid editing (operations for edge, face, and body)
- Preparing engineering documentation: model
and layout (tilemode), model space and paper space, view port operations
in paper space (eg. on, off, fit, hideplot, lock, clip viewport with
object, polygonal, restore), controlling scale between model space and
paper space, and defining plot settings and plot style
