Various types of projection can be used to understand a 3-D structure. Version:- many drawings are amended, each revision must be noted. Step 2 Isometric drawing â step 2 â¢ Step 2 â The angle of the inclined surface cannot be transferred directly. Projection:- the projection â¦ Types of projections 1. A compressed handbook designed for the students of engineering disciplines for learning the basics of engineering drawing. Locate the corners of the inclined surface and then draw lines to connect the corners â¢ Notice that edges that are parallel in the orthographic views will also be parallel in the isometric drawing . Q3: What are the two fundamental methods of shape representation used in engineering drawing? List the advantage of oblique projection. Compass and Divider Fig. 1.10 French Curves .2 Drawing Standards Company name:- name of the company. Date:- the date the drawing was produced or last amended. Graphical projection has an important role in machine drawing and design. Checked:- before manufacture, drawings are usually checked. Notes:- any note relevant to the drawing. A3: Theory of projection is the base for the background information necessary to shape representation in graphics. But the projection of these edges, i.e., aâbâ, aâdâ & aâa1â² are at an angle of 120º to each other and also they are foreshortened to the same length. â¢ Isometric drawing is important to engineering designers as the drawing shows clearly what that has been designed â¢ It is also useful for equipment designers as they can easily interpret the method of construction of an object or equipment. Two widths of lines are typically used on drawings; the thick line width should be 0.6 mm and the thin line width should be 0.3 mm. Various Types of Pictorial Drawings Oblique Projection After reviewing this material, students will know how to do the following: Describe how an oblique projection is created. Muhammad Umair Akram 9/1/2015 MUHAMMAD UMAIR AKRAM 1 Types of Projections Engineering Drawings âIt is actually the language of lines that is used to convey the concept of design of anything from designerâs mind to the manufacturer or the readerâ. Know how to place circle when creating an oblique drawing. drawings from given orthographic projections of an object. Scale:- the scale of the drawing. The front view of the cube, therefore, represents its isometric projection.
