What is the purpose of hidden lines and centerlines?

Hidden lines show edges of details that are not visible from the point of view shown in the drawing. Center lines define the center of arcs, circles, or symmetrical parts.

How does a perspective drawing differ from an isometric drawing of the same object when would you use a perspective view in lieu of an isometric drawing?

How does a perspective drawing differ from an isometric drawing of the same object? When would you use a perspective view in lieu of an isometric drawing? You would use isometric when drawing things from above, like a house plan, while perspective is used to show what the object’s entire design appears to be.

What are the 3 main views of a drawing that are required to depict an object?

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 do you find isometric view?

In an isometric drawing, the object appears as if it is being viewed from above from one corner, with the axes being set out from this corner point. Isometric drawings begin with one vertical line along which two points are defined. Any lines set out from these points should be constructed at an angle of 30 degrees.

What are the hidden view in isometric?

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 is an isometric sketch?

Isometric Sketch or isometric drawing is a pictorial representation of an object in which all three dimensions are drawn at full scale. It looks like an isometric projection. In this case, all the lines parallel to its major axes are measurable.

How do isometric drawing and traditional drawing differ from each other?

Isometric drawing is different than drawing in one or two point perspective because isometric drawings lack a vanishing point. What distinguishes an isometric drawing from any other drawing is the use of angles. The axes of isometric grid paper are drawn so that the horizontal axes are drawn at 30 degree angles.

When would an isometric view be more appropriate than a perspective view?

Isometric drawings are more useful for functional drawings that are used to explain how something works, while one-point perspective drawings are typically used to give a more sensory idea of an object or space.

What mean by isometric view?

Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees.

What are the methods for drawing isometric views?

Following method is used for drawing isometric scale: After drawing a horizontal line, draw two lines at 45° and 30° angle with it. Put marks on the 45° line according to the actual scale. Now draw perpendicular offsets from 45° line up to 30° line which will represent the isometric scale.
