Quick Answer: Where Do You Put Hidden Lines?

How do you use 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..

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 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.

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 does a hidden line look like?

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.

What are hidden detail lines?

Hidden detail occurs when a feature of an object cannot be seen in one or more views. For example, we know the cup. below is hollow, we can see this in the plan. To show that the cup is hollow in the Elevation and the End Elevation we add dashed lines. Dashed lines are drawn as shown (the dashes are usually 3mm long).

Which lines on a drawing should be the thickest?

The direction of the cutting line is shown with a line called a cutting plane lineHeavy dashed line that shows a theoretical cut through an object.. This is the thickest line that may appear on a drawing.

What are the two major methods of dimensioning?

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.

What do hidden lines in orthographic projection?

What do hidden lines in orthographic projections denote? Explanation: Hidden lines denote those parts which cannot be seen when viewing the object. They are used when there are holes or slots in the object if they cannot be viewed directly. Change of plane is indicated by outlines.

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.

When hidden lines meet their lines should?

Rule 2: Hidden lines should always begin and end with a dash. An exception is when the hidden line begins or ends at a parallel visible or hidden line.

What are leader lines?

A leader line is a line that establishes a connection between a graphical representation of an item and some text. A leader points to a bit of our drawing and says: … A leader line also has a terminator and some text. A leader line may have a reference line under the text.
