Front

A preliminary visual of an idea for a design. Most of these sketches are not full size and have little detail. Their purpose is to help quickly explore possible alternative designs.

Thumbnail Sketch

Front

This type of paper uses perpendicular lines to create a grid.

Back

Cartesian

Front

A sketch in which an object’s parallel edges are drawn with parallel lines, typically at 30-degree angles to the horizontal baseline. There are no vanishing points, and three sides of the object can be seen simultaneously.

Isometric Sketch

Front

This graph paper uses lines at a 30-degree angle to create a grid.

Back

Isometric

Front

A sketch, typically including the top, front, and right primary views of an object that are drawn using orthographic projections. An isometric sketch of the object is often included.

Multiview Sketch

Front

Graph paper separated into four equal areas. The top left area shows the orthographic sketch from the top view, the bottom left area shows the orthographic sketch from the front view, the bottom right area shows the orthographic sketch from the right view, and the top right area shows the isometric sketch.

Multiview Graph Paper

Front

Very lightly drawn lines that you can use to help you draw other lines properly. You can erase these lines after you sketch an object.

Back

Construction Lines

Front

Thick solid lines used to show visible edges of an object. Sometimes construction lines are converted to these lines.

Back

Object Lines

Front

Lines that are used to show interior (inside) details not visible from a particular view of an object.

Back

Hidden Lines

Front

Lines that are used to show the center of arcs, circles, or symmetrical parts of an object. Looks like: ---  -  ---  -  ---  -  ---  -  ---
