Activity 2.1 Isometric Sketching
In activity 2.1. we learned about isometric and oblique pictorials. A pictorial drawing is a two dimensional illustration of a three dimensional object that shows 3 faces of an object in one view and that provides a realistic view of an object. Oblique pictorials start with a straight on view of one of the objects which is most likely the front view. They are divided into oblique cavalier pictorials that show the full height, width, and depth of an object and oblique cabinet pictorials that show the full height and width of an object but only half of an object's depth. Isometric pictorials include 3 adjacent cube face that share a point that are each 120 degrees and the object's width, depth, and height are equal.
Conclusion Questions
1. What are the advantages and disadvantages to using an isometric pictorial compared to using an oblique pictorial in technical drawings? The advantages to using an isometric pictorial compared to using an oblique pictorial in technical drawings are that isometric pictorials add a certain depth or realism to the object's drawing due to the equilibrium of each of its sides. The disadvantages to using an isometric pictorial compared to using oblique pictorial in technical drawings is that oblique pictorials sometimes can be considered more realistic than isometric views due to dimensions of its oblique cabinet view and due to the truthfulness behind showing the full depth of an object with oblique cavalier pictorials.
2. What is the difference between a two-dimensional sketch and an isometric sketch? The difference between a two-dimensional sketch and an isometric sketch is that while a two-dimensional sketch displays the object in an understandable way, an isometric sketch adds more dimension and realism to whatever one is drawing that can't be noticed in a two-dimensional sketch which only has height and width unlike the height, width, and depth of an isometric drawing.
3. Why do designers use tonal shading? Designers use tonal shading in order to enhance the appearance of a person's perspective sketch and to create a more realistic presentation.
