Engineering Graphics | Projections of a Hexagonal Prism/Pyramid (Axis Perpendicular to HP) - Fig 12.18
​Video Description:
​Welcome back to our Engineering Graphics Channel! In this video, we'll walk through the solution shown in Fig. 12.18, which corresponds to problem 12.2 (c): Drawing the projections of a Regular Hexagonal solid.
​The problem likely involves:
​Drawing a Regular Hexagon of 25\text{ mm} side in the Top View.
​Keeping one of its sides parallel to the x-y line (as shown by side 2-3 or 5-6).
​Projecting the Front View with a specific axis length (e.g., 50\text{ mm} for a prism or similar height for a pyramid).
​Crucially, the problem mentions cutting the axis 50\text{ mm} long and completing the views, which suggests this figure might represent a sectioned solid (like a prism with a part removed).
​What You Will Learn:
​✅ Hexagon Construction: How to accurately draw a 25\text{ mm} side hexagon with a side parallel to the x-y line.
​✅ Orthographic Projection: Step-by-step projection of all corner points from the Top View (1, 2, 3, \ldots) to the Front View (1', 2', 3', \ldots).
​✅ Drawing Solids: Representing the true shape and size of a solid's base and height (here, 50\text{ mm}).
​✅ Interpreting the Views: Understanding how the coordinates like a', b', c', \ldots are used to complete the final projections, especially after a hypothetical cutting plane is applied.
​If you are struggling with the projections of prisms or pyramids, this video is your complete guide!
