What is the purpose of hidden lines?
A hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen. Sometimes they are used to make a drawing easier to understand. Often they are omitted in an isometric view.
What are the three regular views?
Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object. These views are known as front view, top view and end view. Other names for these views include plan, elevation and section.
How are hidden lines represented on a drawing?
It is standard practice to use dashes to represent any line of an object that is hidden from view.

Which type of drawing gives the most accurate shape description of an object?
In multiview drawings, generally three views of an object are drawn, and the features and dimensions in each view accurately represent those of the object. The frontal plane of projection is the plane onto which the front view of a multiview drawing is projected.
What is the most realistic pictorial sketch?
A perspective sketch presents the most realistic looking view. It shows the object much as it would appear in a photograph—portions of the object that are farther from the viewer appear smaller, and lines recede into the distance.
Which type of pictorial drawing is most natural in appearance?
Isometric drawing
