Answer:
1.)Front view of an object shows the width and height dimensions. Page 7. Horizontal plane of projection. Horizontal plane of projection is the plane onto which the Top View of the multi-view drawing is projected. Top view of an object shows the width and depth dimensions.
2.) 3D views are named from the perspective of the viewer The Left view, is on the left of the object when you look at the front, from the outside of the object. Likewise, the back view is on the back of the object, as you look at the front of the object, from outside the object.
3.)surfaces of the object positioned so that they are parallel to the sides of the box, six sides of the box become projection planes, showing the six views – front, top, left, right, bottom and rear.
4-5.)In the First Angle System, the top view is placed below while the front view is upward and the side view is by the side of the front view. In the Third Angle System, the top view is upward while the front view is downward and the side view is towards, aside from the front view.
6-7.)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.
8-9.)Hidden lines are used to show surfaces that are not directly visible. All surfaces must be shown in all views. If an edge or surface is blocked from view by another feature, it is drawn using a hidden line. Figures 4-11 and 4-12 show objects that require hidden lines in their orthographic views.
10-12.)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.
