## What is a hidden line in engineering?

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 does a hidden line represent in engineering drawing?

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.

#### What does hidden line mean in construction?

Hidden lines: indicate areas or objects not visible on the surface, or objects hidden behind others. They are also used to show objects above the cutting plane of a floor plan, such as wall cabinets, beams, arches, etc.

What are the 6 basic lines used in technical drawing?

Using the Alphabet of Lines

• Construction Line. This line is used mainly in sketching, which is a freehand drawing technique.
• Visible Object line. This line is used to draw all the edges of the object.
• Hidden Object Line.
• Centre Line (or centreline)
• Extension Line.
• Dimension Line.

What is the purpose of a visible line?

The visible object line (also visible line) is used to outline the visible edges of the object being drawn. They should be drawn so that the views stand out clearly on the drawing. All of the visible object lines on the drawing should be the same weight.

## What is the purpose of hidden lines and centerlines?

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 8 types of lines?

• Diagonal. a straight line from one corner to another corner.
• C curves. Looks like a C.
• S Curves. Looks like an S.

#### What is visible line in drawing?

Visible lines are the edges or “outlines” of an object. They are drawn as solid lines with a thick/heavy weight.

What is the purpose of hidden line?

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.

Why are hidden lines drawn as dashes?

It is standard practice to use dashes to represent any line of an object that is hidden from view.

## What is the use of hidden lines in engineering drawing?

Hidden or broken lines are used to see what is hidden or behind a solid object, or if you are creating a pattern development, hidden lines are used to know what part is being folded. There are many types of lines used in engineering drawing and it varies on what type of pencil you are using,…

### What are hidden lines (thin type lines)?

Hidden Lines (Thin) type lines consist of thin short dashes, closely and evenly spaced. These lines are drawn to represent hidden or invisible edges of the objects.

#### What is the difference between visible line and hidden line?

A visible line, or object line is a thick continuous line, used to outline the visible edges or contours of an object. 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 is the primary objective of a hidden line diagram?

Your primary objective is to provide clear, unambiguous information, and on simple stuff, a dimension to a single, clear hidden line is clear and unambiguous. The problem with allowing these exceptions is that they will then multiply.
