## What does a phantom line look like?

Center Line: Centerlines consist of alternating long and short evenly spaced dashes, with a long dash at each end and short dashes at point of intersection. Phantom Lines: Phantom lines are thin lines used to indicate alternate position of the parts of an object, repeated detail, or the location of absent parts.

## Where do you put hidden lines?

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.

## Which type of lines are used to represent hidden edges?

Figure 5: Use of dashed lines to represent edges hidden in views of a complicated object.

## What four lines are used to aid in dimensioning?

There are four methods: parallel, running, chain, and combined dimensioning. Some methods of dimensioning a drawing can create an accumulating error.

## What is the heaviest line in a drawing?

The heaviest line weight indicates the ground line cut. The next heaviest line weight “profiles the planes closest to the plane of projection” (Ching & Juroszek, 1998, p. 152). Medium line weight indicates distance from picture plane, progressively getting lighter to describe objects further from the picture plane.

## What are the 7 types of lines?

There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc. and are often very expressive.

## What type of lines are used for hidden details?

## Do you draw hidden lines in isometric drawings?

## What hidden line means?

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 are alphabet lines?

The Alphabet of Lines is a list of line symbols that engineers use in technical drawings to communicate specific shapes, sizes or surfaces. In the Alphabet of Lines, thick, dark lines represent the outline of an object, showing its visible surfaces and edges.

## What are the types of line?
