# Practice Question 1

**Draw the below diagram in AutoCAD**

#### Note: Try to create the figure yourself first. If you are unable to create, follow the below steps.

The method to create a figure may involve different commands from person to person. We are required to check if the output figure and dimensions are correct or not.

## Solution:

Since the values of dimensions are greater, we need to specify the limits first.

The steps to set the limits are listed below:

- Type
**LIMITS**on the command line or command prompt. - Press
**Enter**or**spacebar**. - Write the coordinates of the
**lower-left corner**. For example, (**0, 0**). - Press
**Enter**. - Write the coordinates of the upper-right corner. For example, (
**150, 150**). You can adjust the limits according to the choice. - Press
**Enter**. - Write Z. Here, Z signifies Zoom.
- Press
**Enter**. - Write E. Here, E signifies Extend.
- Press
**Enter**.

#### Note: Here, the value of coordinates will be measured from the origin of the UCS.

We can also draw a figure without using UCS. It depends on our choice.

We can now start our drawing.

The steps to create above figure in AutoCAD are listed below:

- Place the UCS at the center of the viewport. The UCS looks like the below image:

We can place it anywhere in the viewport according to our requirements. - Type
**Rec**or**Rectangle**on the command line. - Press
**Enter**. - Click on the first corner point on the origin of the UCS. We can also type
**0, 0**. - Specify the length and breadth of the rectangle in the form of
**@length**, width. Here, we will create a large rectangle of dimension**105 x 60**. Example â€“**@105, 60**. - Press
**Enter**. - Type L or line on the command line and press
**Enter**. - Type the coordinate
**35, 0**and press**Enter**. - Type the coordinate
**35, 60**and press**Enter**. - Press
**Enter**.

The line formed using the above steps will look like the below image:

- Type L or line on the command line and press
**Enter**. - Type the coordinate
**70, 0**and press**Enter**. - Type the coordinate
**70, 60**and press**Enter**. - Press
**Enter**. - Now, the figure will look like the given image:

Now, we have to create two triangles. Some lines will be declared using relative coordinates (with @) because the value is not specified from the origin. - Type
**L**or**line**on the command line and press**Enter**. - Type the coordinate
**0, 60**and press**Enter**. - Type the coordinate @
**35<60**and press**Enter**. - Type the coordinate
**35, 60**and press**Enter**. - Press
**Enter**.

**For another triangle:** - Type
**L**or**line**on the command line and press**Enter**. - Type the coordinate
**70, 0**and press**Enter**. - Type the coordinate @
**35<-60**and press Enter. We can also type @**35<300**because the angles are measured in counter- clockwise direction. - Type the coordinates
**105, 0**and press**Enter**. - Press
**Enter**.

Now, the figure will look like the given image:

For better understanding, the coordinates are marked in the below image:
