Autocad Draw Circle on Circle

Circles and Ellipse control

Circles

The circles are widely used in design and drawings.

The circle command is used to depict a circle by specifying the middle indicate and radius.

Let's empathise past 2 examples.

Example 1:

The steps to create a circle are given beneath:

1. Click on the Circle icon on the Ribbon Panel, as shown in the below image:
   
   OR
   Type Circumvolve or C on the command line and press Enter.
2. Specify the center point of a circle on the workspace or viewport.
3. Specify the radius of the circle.
   Or
   To specify diameter, type D - press Enter - specify the bore of the circle.
4. Printing Enter.

Example ii:

Nosotros tin can also create the circle randomly. The steps are listed below:

1. Click on the Circle icon on the Ribbon Console, as shown in the below image:
   
   OR
   Blazon Circumvolve or C on the control line and printing Enter.
2. Specify the centre signal 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. 3 indicate circle
3. Tangent circumvolve

one) ii Point circle

Nosotros can create a circle by specifying the ii endpoints.

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

Permit'due south understand with an example.

Case: A circle between 2 lines.

The steps to create a two-point circle are listed below:

1. Select the ii-Indicate circle option from the drop-down listing of the circle, as shown in the beneath image:
   
   Or
   Type C or Circle on the command line - Press Enter- type 2P - printing Enter.
2. Click on the first endpoint of a circumvolve bore. We can also type the value to specify the endpoint.
3. Click on the second endpoint of a circle bore through the cursor, as shown in the below image:
   
   We tin can specify the endpoints co-ordinate to the requirements.
4. The circumvolve volition be created, every bit shown in the beneath prototype:

2) three Point circle

We tin create a circle by specifying the 3 endpoints.

Let's understand with an example.

Example: A circumvolve betwixt iii edges.

The steps to create a three-point circle are listed below:

1. Create three edges.
2. Select the 3-Point circle selection from the driblet-downwardly list of the circle, as shown in the below image:
   
   Or
   Type C or Circle on the command line - Press Enter- type 3P - printing Enter.
3. Click on the beginning indicate.
4. Click on the 2nd point.
5. Click on the third betoken.
   The three points are shown in the below image:
   
6. The circle will exist drawn, equally shown in the below image:

Tangent circle

The tangent circle command is used to describe circles on the tangent.

At that place are ii types of the tangent circle, that appear on the drop-downwards list of the circumvolve icon on the ribbon panel, as shown in the below epitome:

Let'south empathise with three examples.

Case ane: Tan, Tan, Radius

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

1. Draw two lines in the viewport, as shown in the beneath image:
   
2. Select the Tan, Tan, Radius circle option from the driblet-downwards listing of the circle on the ribbon panel.
   Or
   Type C or Circle on the control line - Press Enter- blazon ttr - press Enter.
3. Click on the first point on the beginning tangent.
4. Click on the second indicate on the other tangent.
5. Specify the radius of the circle. For example, four.
6. The circle will be drawn on the two tangents, equally shown in the below image:

The circle volition be adjusted co-ordinate to the specified radius.

Example ii: Tan, Tan, Tan

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

1. Depict three lines on the viewport, every bit shown in the below image:
   
2. Select the Tan, Tan, Tan circumvolve option from the drop-downwardly list of the circumvolve.
3. Click on the first indicate on the kickoff tangent.
4. Click on the 2d indicate on the 2nd tangent.
5. Click on the tertiary betoken on the third tangent.
6. The circumvolve will be drawn on the 3 tangents, as shown in the below image:

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

Instance three: Tan, Tan, Radius

To create a circle inside a triangle

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

1. Draw a triangle in the viewport, as shown in the below paradigm:
   
2. Select the Tan, Tan, Radius circle option from the drop-down list of the circumvolve. Or
   Blazon C or Circle on the command line - Printing Enter- type ttr - press Enter.
3. Click on the start point on 1 side of the triangle.
4. Click on the 2nd and 3rd points on the other side of the triangle.
5. The circumvolve will be drawn inside the circumvolve, as shown in the beneath paradigm:
