What drawing instrument is used to reduce and enlarge drawings?

Pantographs
Pantographs are used for reducing or enlarging engineering drawings and maps and for guiding cutting tools over complex paths.

How would you describe a drawing which has been reduced or enlarged from its original size to a specified scale?

In plain English, a scale drawing is a drawing which has been reduced or enlarged from its original size, to a specified scale. (Defined by Collins English Dictionary). The scale is a ratio of the size of the drawing to the size of the original object being drawn. This may be referred to as a scale ratio.

How do you mention reduced scale in drawing?

A full-size drawing is done at a scale of 1:1 or 1/1 or 1 divided by 1 or actual size. Using a Reduction Scale, a drawing done to scale 1:2 or ½ or 1 divided by 2 is said to be “half scale.”

Which is the tool used to enlarge any part of the drawing?

Explanation: Magnifier tool in paint is used to zoom in and zoom out the picture.

What drawing instrument that is used when drawing arcs and circles?

compasses
A compass, more accurately known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs.

Which of the following represent reducing scale?

3. Which of the following scales is a reducing scale? Explanation: The representative fraction 1:3 indicates that the dimension of the drawing is one-third of the actual object. Since the drawing is smaller than the actual object, this type of scale is called a reducing scale.

What is enlarged scale?

Explanation: Enlarging scale means that the drawing is drawn with the bigger dimensions in comparison to the actual dimensions of the object. A representative fraction of 1:0.2 means 5:1, i.e. the drawing is five times bigger than the actual object. Hence the scale is enlarging scale.

What tool is used to magnify images?

The Zoom Tool is used to zoom in and out of an image.

What tool is used for drawing circles?

compass
compass is traditional tool for drawing circles A compass is the traditional tool for drawing precise circles, and its sharp point acts as a pivot. A pencil is attached to the other end. To set the compass to the desired radius, use a ruler to adjust the two end points to the desired length.

What kind of scale do you use for drawing?

Architects, engineers and other designers use different types of scales to prepare technical drawing. Some of the most common scales include metric scale, architects’ scale etc. 1. Metric scale: based on proportional ratio. It describes the ratio of the drawing compared to the actual size of the object.

When do you draw an object to scale?

When you draw an object to scale, the drawing represents a ratio of the object size. With scale, you can draw large objects that are too big to be drawn full size at a reduced size or objects that too small to an enlarged size. Architects, engineers and other designers use different types of scales to prepare technical drawing.

Is the drawing the same size as the object?

The drawing is the same size as the object. For example: Mapping Skills – What you need to know! b) Reducing scale: – the object is represented smaller in a drawing c) Enlarging scale: : – the object is represented larger in a drawing 2. Imperial scale: based on fractional ratio.

What kind of pencils are used for mechanical drafting?

Medium pencils– are used for general purpose work in drawing. Soft pencils– are too soft to be used in mechanical drafting. They are very useful for art work of various kinds. MECHANICAL DRAFTING 11 K to 12 – Technology and Livelihood Education .
