Question 1

What is NCEA AS 91338 about?

Accepted Answer

This standard asks you to create working drawings — detailed technical drawings that show how a design is actually built or constructed. You need to use proper technical drawing conventions (like scales, dimensions, section lines, and labels) to communicate both the practical and visual details of your design so that someone else could understand and build it from your drawings.

Question 2

What do students need to do for AS 91338?

Accepted Answer

1. Produce a complete set of linked 2D working drawings (plans, elevations, and cross-sections) that work together to explain your design 2. Use recognised technical drawing conventions correctly — including standard scales, line types, labels, dimensions, and title blocks with page numbering 3. Show technical details and complex information through assembly drawings and enlarged detail drawings that clearly relate to your main drawings 4. Add accurate dimensions (including vertical dimensions for spatial designs) verified using standard scales so the design can be built to the correct size 5. Communicate how the design functions and what it looks like — showing both practical details (like materials, construction, furniture placement) and visual qualities (like materiality and aesthetic choices)

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91338?

Accepted Answer

Achieved: You produce a set of interconnected 2D working drawings showing plans, elevations, and sections with basic technical details, recognised conventions, and mostly correct scales. Merit: Your drawings are skilfully and accurately made with clear communication of technical details, proper use of linking tools (section lines, compass directions, page numbering), correct standard scales, and complex detailing that shows construction information related to your design. Excellence: Your drawing set communicates technical details to a high standard with effective conventions, includes enlarged details accurately linked to the main drawings, maintains consistency across all related sheets, and flows logically so the relationship between parts is easy to understand.

Question 4

What mistakes do students typically make in AS 91338?

Accepted Answer

1. Forgetting to add vertical dimensions to elevations in spatial designs — this means someone couldn't understand the full height and scale of the space 2. Using non-standard scales (like 1:48 instead of 1:50) because you didn't properly format your CAD software, rather than consciously choosing to do so 3. Not including enough technical details or assembly views — for example, a floor plan without labelled rooms or furniture placement, or a product drawing without dimensioning to show overall size
