## What is AutoCAD scale?

Scale Factor. **Multiplies the dimensions of the selected objects by the specified scale**. A scale factor greater than 1 enlarges the objects. A scale factor between 0 and 1 shrinks the objects. You can also drag the cursor to make the object larger or smaller.

## How do you scale something?

To scale an object to a smaller size, **you simply divide each dimension by the required scale factor**. For example, if you would like to apply a scale factor of 1:6 and the length of the item is 60 cm, you simply divide 60 / 6 = 10 cm to get the new dimension.

## What is a scale of 1 100?

Ratio scales

If the scale of the plan is 1 : 100, this means the **real measurements are 100 times longer than they are on the plan**. So 1 cm on the plan represents a real length of 100 cm (1 metre)

## How do you find the scale factor?

The basic formula to find the scale factor of a figure is: **Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape**. This can also be used to calculate the dimensions of the new figure or the original figure by simply substituting the values in the same formula.

## How does AutoCAD calculate scale?

With a calculator, **divide** the intended length by the measured length. Enter the SCALE (Command). Select a base point, such as 0,0,0. Enter the obtained scale factor to adjust all objects in the drawing model to their correct size.

## How do I know the scale of my drawing in AutoCAD?

Press Ctrl + A on your keyboard to select all elements in the drawing. **Type ‘scale’ in to the command bar and press enter**. AutoCAD will ask ‘SCALE Specify base point:’, type ‘0,0’ (without the quotes) and press enter. to view the data.

## What is full size scale?

Full scale is simply **letting one inch on a ruler, steel rule**, or draftsman’s scale equal one inch on the actual object. Rules of this kind are usually divided into 1 /16” or 1 /32” units. The first measurement exercise will be with full size.

## What does a scale of 1 2 mean?

Metric Scale**Half scale** is 1:2. It is helpful to think of this as one unit on the drawing equals two units on the object. A small object can be enlarged on the paper and drawn in 2:1 scale. This means the drawing of the object is twice as large as the object itself.

## What are the standard drawing scales?

Referred to as **1:10, 1:20, 1:30,1:40, 1:50 or 1:60 scale**. Typically in civil engineering applications, 1:10 (1″=10′) is used exclusively for detail drawings. 1:20 and 1:40 scales are used for working plans.
