Engineering Graphics and Design Thinking

Q1. Draw the Orthographic Views (Front View, Top View, and Left Side View) for the given 3D isometric stepped bracket using First Angle Projection Method with proper dimensions.

Key Points: Use 1st angle projection: Front view above reference XY line, Top view directly below Front view, Left side view projected on the right. Maintain projection lines and full dimensioning in mm.

Q2. A regular hexagonal prism of base side 30 mm and axis height 65 mm rests with its base on HP. A cutting plane inclined at 45° to HP cuts the prism passing through the axis at a height of 35 mm from base. Draw the development of the lateral surface.

Key Points: Draw the 6-panel unrolled perimeter (6 x 30 = 180 mm). Project cutting plane intersection points from the front elevation across all 6 vertical edges and connect with straight lines.

Q3. A right circular cylinder of diameter 50 mm and height 70 mm rests on HP. Draw the Isometric Projection of the truncated cylinder cut by a plane inclined at 30° to HP.

Key Points: Construct isometric scale (True length x 0.816). Draw isometric box with 30°-30° axes, construct elliptical top section using 4-center method.
