AutoCAD 2D drawings are commonly drawn in model space at a 1:1 scale (full-size). In other words, a 12-foot wall is drawn at that size. The drawings are then plotted or printed at a plot “scale” that accurately resizes the model objects to fit on paper at a given scale such as 1/8″ = 1′.

## Why scale is used in AutoCAD?

**Enlarges or reduces selected objects, keeping the proportions of the object the same after scaling**. To scale an object, specify a base point and a scale factor. The base point acts as the center of the scaling operation and remains stationary.

## How do you find the scale in AutoCAD?

**To Check the Scale of a Scale Area or Viewport (AutoCAD Mechanical Toolset)**

- Click View tab Viewports panel Scale Monitor. Find. The Scale Monitor dialog box is displayed.
- In the drawing area, move the cursor over the scale area (or a viewport ) and check the Scale Monitor dialog box.
- Press ENTER to exit this command.

## How do you do scale drawings?

Drawings can be scaled up or down using either a calculator or a scale rule. To scale a drawing using a calculator: **divide the measurement by the scale if you want to reduce the drawing in size**, or. multiply the measurement by the scale if you want to increase it in size.

## How do you calculate scale?

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 I change the scale of a drawing in AutoCAD?

**To Change the Scale of a Drawing View**

- Move the cursor over the drawing view to edit. The drawing view border appears.
- Click an empty area inside the drawing view. Grips appear.
- Click the lookup grip. A menu appears.
- Select the new scale from the menu.

## What is a word scale?

a) The word **scale expresses the scale in words**, e.g. “One centimetre represents half a kilometre.” b) The ratio scale is written as a ratio or a fraction,e.g. 1:50 000 or 150000. This means that one unit (e.g. cm) on the map represents 50 000 of the same unit (cm) of the earth surface.
