A good speed in drawing work should be achieved, because “time is money” in the industry. Accuracy, neatness and legibility are of great importance in engineering drawing. 1.
What is the name of the projection of an object?
The projections of the object are perpendicular with the planar screen, and hence, the name ‘orthographic’. Perspective Projection: This is a simple technique of drawing an object as how one views it. The observer’s eye position, height, and the distance from the object, all influence the outcome of the drawing.
Which projection method is used to show the front view of an object in space?
Orthographic Projection: In this method the object is placed in space in such a way that the front view of it is captured in the vertical plane, and the top view of the same, is captured in the horizontal plane. The projections of the object are perpendicular with the planar screen, and hence, the name ‘orthographic’.
Is engineering drawing a grammar?
Engineering drawing also has its grammar in the theory of projections, its idioms in conventional practices , its punctuations in the types of lines, its abbreviations, symbols and its descriptions in the constructions. Students should not get confused Engineering Drawing with Artistic Drawing.
