Multi-view drawings

In this video, I dive into multi-view drawings, which are the standard way to represent a 3D part in 2D for manufacturing. The key to creating these drawings is understanding how to select and arrange your views. I begin by explaining that the front view should always be the most descriptive view of the part's overall shape, using a car as an example where the side view is more descriptive than the actual front. I then stress the importance of using the least number of views possible to fully describe the object. I demonstrate the projection rules, emphasizing that every corner must be projected to the adjacent view, and introduce the miter line (a 45-degree line) as a crucial tool for accurately transferring the depth measurement between the top and side views. I also introduce hidden lines (dashed lines) to represent features that cannot be seen from a particular view, and walk through two detailed examples to solidify the entire process of drawing complete, accurate multi-view projections.
