AutoCAD Hangers Basic Ttr and Sweep
This AutoCAD tutorial is show you how to make simple 3D hangers to learn more about circle ttr (tan tan radius) and also sweep command.
Level: Beginner
Dimensions: Free style
Focus commands: Circle and Sweep
- First on front view, draw circle by using circle command
- Use line command to make neck and body of hangers
- After it use mirror command to duplicate the last line object
- Use arc command to make arch below the hanger body, and delete line object
- Now on hanger neck, use circle ttr command
- And the trim it
- Also use these steps for the body
- Duplicate hanger body by using mirror command
- Change into top view and then use orbit to make better view
- Next, use join command to convert into polyline object
- Draw circle on hangers head
- Final steps, use sweep command to convert 2D hanger into 3D model

Understanding AutoCAD Circle Command
In AutoCAD, circle command is use to draw a circle object base on radius or center. There are also any options to draw a circle with 2 points, 3 points, and two tangents/ttr.
Command: C
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter]:Options in circle command:
- Default using center point
- 3P, draw circle with 3 point
- 2P, draw circle with 2 point
- Ttr, draw circle base on 2 tangent
- Default using radius to specify circle size
- Diameter, draw circle base on diameter
Example how to use circle command
Circle Radius
- Type c (enter)
- Specify first point (click anywhere on drawing area)
- Give radius point (enter)
Circle 3 point
- Type c (enter)
- Type 3p (enter)
- Specifiy first point
- Specify Second Point
- Specify third point
Circle Ttr
- Type c (enter)
- Type ttr (enter)
- Click on first and second object
- Give radius size (enter)
