Assam ASSEB HS Skill Engineering Drawing case studies
Assam ASSEB HS Skill Engineering Drawing · Put your knowledge to work in context.
Engineering Drawing is offered as a skill subject in the Assam Higher Secondary curriculum, examined under the Assam State School Education Board (ASSEB, formerly AHSEC). It is intended for HS students who want a practical, drawing-based subject alongside science or vocational streams, and it also serves as an entry point for those aiming at diploma, polytechnic or technician-level pathways. The Assam ASSEB HS Skill Engineering Drawing case studies are 5 cases and about 3,251 words.
1Dimensioning a Stepped Shaft for the Machine Shop
An ASSEB candidate is preparing a shop drawing of a stepped shaft at 1:2 on an A3 sheet. The shaft is 120 mm overall: Ø30 for the first 45 mm, Ø40 for the next 35 mm, and Ø25 for the last 40 mm.

A hexagonal prism of base side 25 mm and axis 65 mm is to be drawn with one base edge on HP, that base edge parallel to VP, and the axis inclined at 40° to HP. The candidate draws the final elevation first: a hexagon standing on a corner with its axis at 40° to xy, and then projects the plan from it.

A sheet-metal workshop needs a square-to-round transition piece: square top 90 mm × 90 mm, circular bottom Ø50 mm, vertical height 70 mm, made from 1 mm mild steel in two halves. The candidate tries the radial-line method used for a cone, extending the sides of the square to a single apex, but the development does not close and the blank is 15 mm short at the seam.
