Fig. Q.3.1 shows a pictorial view of an object. By using first angle method of projection draw i) Front view ii) Sectional left hand side view along symmetry of object iii) Top view. Give all required dimensions.
Understand the Problem
The question requires creating orthographic projections (front, sectional left side, and top views) of an object based on the given pictorial view, using the first angle method of projection and including all necessary dimensions.
Answer
Draw front, sectional left side, and top views using first angle projection.
To draw orthographic projections in the first angle method: i) Create the front view by establishing the most descriptive face directly. ii) Generate a sectional left-hand side view based on the symmetry line. iii) Draw the top view from a top-down perspective, aligning features with the front view.
Answer for screen readers
To draw orthographic projections in the first angle method: i) Create the front view by establishing the most descriptive face directly. ii) Generate a sectional left-hand side view based on the symmetry line. iii) Draw the top view from a top-down perspective, aligning features with the front view.
More Information
The first angle projection method is commonly taught in Europe and Asia, where the object is placed in the first quadrant. This method differs from the third angle, which is standard in the U.S.
Tips
Always double-check symmetry and ensure dimensions from the pictorial view match the orthographic projections.
