The basic types of dimensioning are linear, radial, angular, ordinate, and arc length. Use the DIM command to create dimensions automatically according to the object type that you want to dimension.

Pictorial Sketches • A Pictorial drawing is a view of an object as it would be seen by an observer who looks at the object either in a chosen direction or from a selected point of view. • Pictorial drawings often are more readily made and more clearly understood than are front, top, and side views of an object.

What are the 6 principal views of an object?

In orthographic projection there are six possible views of an object, because all objects have six sides – front, top, bottom, rear, right side, and left side.

How do I find hidden lines in an object?

A drafter—in deciding whether a line in a view should be represented as hidden or as visible—relies on the fact that in third-angle projection the near side of the object is near the adjacent view, but in first-angle projection the near side of the object is remote from the adjacent view.

Do you draw hidden lines in isometric drawings?

Hidden lines in a drawing represent the edges where surfaces meet but are not directly visible. Hidden lines are omitted from pictorial drawings unless they are needed to make the drawing clear. … In general, use centerlines sparingly in isometric drawings.

What type of lines are used for hidden details?

Hidden line Hidden details are shown by a series of dashes making up a broken line. It is normal practice that you place a dash at the beginning of the hidden line and another at the end where it meets an intersecting line.

What is the purpose of hidden and center lines?

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.

What are the lines on a blueprint called?

Phantom lines (see Figure 1-6) are thin lines used to indicate alternate positions of the parts of an object, repeated detail or the locations of absent parts. They are made by alternating one long and two evenly- spaced, short dashes, with a long dash at each end.

What does a centerline look like?

Centerlines indicate a circular feature on a drawing. In 2D, most circular features look exactly the same as features with non-circular geometry. The only way to tell them apart is by adding a centerline, which represents their central axis and confirms their geometry.
