State Level Skill Competitions - Skill-Mechanical Engineering Design - CAD Test Project (Level 2)

Sep 1, 2026

State Level Skill Competitions provide a structured test for Skill-Mechanical Engineering Design (Computer-Aided Design/CAD), focusing on reading technical drawings, creating 3D models from detail drawings, and generating accurate 2D drawings with required dimensions, tolerances, and manufacturing symbols. Eligibility requires competitors born on or after 01 Jan 1997. The CAD test runs for 4 hours, supports Autodesk Inventor v.2016+, and uses a 50-mark scheme combining measurable assessments and industry-expectation judgments, supported by defined infrastructure and health, safety, and environment guidance.

State Level Skill Competitions Skill-Mechanical Engineering Design Test project- Level 2 Skill Explained Computer aided design is the use of computer systems to assist in the creation, modification, analysis, or optimization of an engineering design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communication through documentation, and create a database for manufacturing. CAD output is often in the form of electronic files for print, manufacturing or other manufacturing processes. The technical and engineering drawings and images must convey information such as materials, processes, dimensions and tolerances according to application-specific conventions. Eligibility Criteria- Competitors born on or after 01 Jan 1997 are only eligible to attend the Competition Duration of Test project: 4 hours Preface Section A-Test Project Section B-Marking Scheme Section C-Infrastructure List (Tool and equipment including raw material) Section D- Instruction for Competitors Section E- Health, Safety and Environment Section A Prerequisites for the State/District Competition: Familiarity with the software. (Autodesk Inventor - v.2016 and above) To interpret 2D drawings & create 3D models from detail drawings; To create an assembly of parts in 3D & to produce detail drawing(s) Selection of standards from content library Familiarity with Basic measuring instruments like Vernier caliper, Micrometer & radius gauges and Angle measuring instruments Knowledge in Geometrical dimension and tolerances. Details of the competition: The competitor must be able to read the drawing, model the 3D model, create the 2D drawings from the CAD Model created and dimension it as per the specifications mentioned in the drawing with necessary tolerances and manufacturing symbols. The completed test projects will be evaluated by a jury panel. The test duration is for 4 Hrs. The competition will be on Autodesk Inventor version v.2016 and above. The test is for 50 marks The below drawing is an example of First test – Mechanical Assemblies and detail drawings for manufacture. Figure SEQ Figure \* ARABIC 1- Mechanical Assemblies & detail drawings for manufacture Second level Test will be for 75 marks and for a duration of 4 + 2 Hrs. It will be featuring an additional test of measuring and modelling from a physical part which is called reverse engineering by use of simple measuring tools like Vernier calliper, Micrometer, Radius and Thread Pitch gauges. The below parts are examples of Second test – Reverse Engineering from a Physical part Section B Marking Scheme: The Assessment is done by awarding points by adopting two methods, Measurement and Judgments Measurement –One which is measurable Judgments--Based on Industry expectations Aspects are criteria’s which are judged for assessment Scheme of marking: First test: Mechanical Assemblies and detail drawings for manufacture Create part models for all parts mentioned in the drawing - 20 Marks (All measurable) Create detailed 2D drawing and Assembly drawings– 20 marks (Judgemental: 4-5%, Measurable 90-96%) Approx. Dimensioning and Part list (BOM) – 10 marks (Judgemental: 4-5%, Measurable 90-96%) Approx.

FAQs

Who is eligible to attend the state-level competition?

Competitors born on or after 01 Jan 1997 are eligible to attend the competition.

What software and prerequisite knowledge are required?

Competitors must be familiar with Autodesk Inventor v.2016 and above, be able to interpret 2D drawings and create 3D models, create 3D assemblies and detail drawings, select standards from a content library, and understand geometrical dimensioning and tolerances.

How are marks awarded in the CAD test project?

The assessment uses two approaches: Measurement (measurable criteria) and Judgments (based on industry expectations). The first test totals 50 marks and includes part modeling, 2D/assembly drawings, dimensioning and BOM, with further sub-criteria under a marking form.
