How to Draw a Circle Inside a Square in Autocad

Circles and Ellipse command

Circles

The circles are widely used in design and drawings.

The circle control is used to draw a circumvolve by specifying the heart indicate and radius.

Let'south sympathise by two examples.

Example 1:

The steps to create a circumvolve are given beneath:

1. Click on the Circle icon on the Ribbon Panel, every bit shown in the below epitome:
   
   OR
   Type Circle or C on the command line and press Enter.
2. Specify the center indicate of a circle on the workspace or viewport.
3. Specify the radius of the circle.
   Or
   To specify bore, type D - press Enter - specify the bore of the circle.
4. Press Enter.

Example 2:

Nosotros can as well create the circle randomly. The steps are listed beneath:

1. Click on the Circle icon on the Ribbon Panel, every bit shown in the beneath image:
   
   OR
   Type Circle or C on the command line and printing Enter.
2. Specify the center point of a circle on the workspace or viewport.
3. Specify the endpoint of the radius through the cursor.

Types of Circles

There are three types of circles, which are listed below:

1. two point circle
2. iii bespeak circle
3. Tangent circle

ane) 2 Point circle

We can create a circle by specifying the two endpoints.

The distance between the two specified endpoints will be considered as the diameter of that circle.

Permit's understand with an example.

Example: A circle between two lines.

The steps to create a 2-betoken circumvolve are listed below:

1. Select the 2-Point circle choice from the drop-down list of the circle, as shown in the below prototype:
   
   Or
   Type C or Circumvolve on the command line - Printing Enter- type 2P - press Enter.
2. Click on the first endpoint of a circumvolve diameter. We can likewise type the value to specify the endpoint.
3. Click on the second endpoint of a circle diameter through the cursor, as shown in the below epitome:
   
   We can specify the endpoints according to the requirements.
4. The circle will be created, as shown in the below image:

2) 3 Indicate circle

We can create a circle by specifying the 3 endpoints.

Let's sympathize with an case.

Case: A circle between three edges.

The steps to create a three-betoken circumvolve are listed below:

1. Create three edges.
2. Select the 3-Point circumvolve option from the driblet-down list of the circumvolve, every bit shown in the below prototype:
   
   Or
   Type C or Circle on the control line - Press Enter- type 3P - press Enter.
3. Click on the first point.
4. Click on the second point.
5. Click on the third point.
   The iii points are shown in the below image:
   
6. The circumvolve will be drawn, as shown in the below image:

Tangent circumvolve

The tangent circumvolve command is used to draw circles on the tangent.

In that location are ii types of the tangent circle, that appear on the drop-down list of the circle icon on the ribbon panel, as shown in the beneath epitome:

Let's understand with three examples.

Example 1: Tan, Tan, Radius

The steps to create a Ttr (Tangent tangent radius) circle are listed below:

1. Draw two lines in the viewport, as shown in the below image:
   
2. Select the Tan, Tan, Radius circumvolve option from the drop-down list of the circumvolve on the ribbon panel.
   Or
   Type C or Circle on the command line - Press Enter- type ttr - printing Enter.
3. Click on the first point on the first tangent.
4. Click on the second indicate on the other tangent.
5. Specify the radius of the circle. For example, 4.
6. The circle volition be drawn on the two tangents, equally shown in the below paradigm:

The circle volition be adjusted according to the specified radius.

Example ii: Tan, Tan, Tan

The steps to create a (Tangent tangent tangent) circle are listed below:

1. Describe three lines on the viewport, as shown in the below image:
   
2. Select the Tan, Tan, Tan circumvolve option from the drop-down list of the circumvolve.
3. Click on the first point on the commencement tangent.
4. Click on the 2d point on the second tangent.
5. Click on the tertiary point on the 3rd tangent.
6. The circle will exist drawn on the iii tangents, every bit shown in the below image:

Nosotros can modify the tangent and points according to the requirements.

Example 3: Tan, Tan, Radius

To create a circle within a triangle

The steps to create a circle within a triangle are listed below:

1. Draw a triangle in the viewport, every bit shown in the below image:
   
2. Select the Tan, Tan, Radius circle option from the drib-downwards list of the circle. Or
   Blazon C or Circle on the command line - Press Enter- type ttr - press Enter.
3. Click on the first point on 1 side of the triangle.
4. Click on the second and 3rd points on the other side of the triangle.
5. The circle will be drawn inside the circumvolve, as shown in the below paradigm:
