Exam 2: Sketching

One method for sketching a(n) ____________________ is to first construct a right angle (square corner).

After completion of the basic view in an isometric sketch, parallel receding lines are sketched at ____° angles from each of the corners.

To assist in sketching the arc, ____ points are located on the legs of the angle to indicate where the curve is to begin and end.

Oblique sketches may require the sketching of oblique ____________________.

For sketching isometric circles, the same basic techniques are applied as for sketching a regular circle.

When developing an oblique drawing, after completing the orthographic view, draw parallel receding lines at about ____° angles from the corners of the view to develop the three-dimensional effect.

The extent of the receding lines in oblique sketching is about ____ the length that would be shown for an orthographic drawing.

Lines are first lightly sketched with long overlapping strokes using a pencil with a fairly sharp point.

To develop a(n) ____________________ drawing, an orthographic view of the object is first drawn that best describes the shape and shows the most detail of the object.

____________________ lines are drawn to the right for developing a right oblique drawing and to the left for developing a left oblique drawing.

A(n) ____ is sketched by laying out a rectangle with sides equal to the major and minor axes of it.

To sketch a circle, the same process for sketching an arc is repeated for all ____ of the circle.

An isometric sketch has all of its surfaces shown at ____° angles.

When developing an isometric sketch, receding lines are reduced in length (foreshortened) to about ____ of the orthographic line length.

____ are often used in place of finished drawings, particularly when time and circumstances do not permit preparation of a finished drawing.

Heavy lines are drawn by dulling (rounding) the point of the pencil and applying enough pressure to produce the line weight desired.

Lines are not usually shown for any part of the object that is not visible.

An oblique sketch is completed by repeating the same lines shown on the original orthographic view at the starting points of the receding lines.

A ____ is a freehand drawing used to describe the shape and size of an object. It is a means of quickly expressing an idea.

To develop an isometric sketch, isometric ____________________ paper is preferable.
