How To Use ‘Helix’ Command In AutoCAD® 2D?
To draw spirals in Autocad®, click on the ‘Draw’ pop-up menu as shown by the red arrow above. Then click on the ‘Helix’ command as in the red box.
After entering into the ‘Helix’ command, click to define the center point of your spiral as shown by the red arrow. Then you need to enter a starting radius value by entering a value or by clicking with your mouse as shown by green arrows.
The first radius value that you specified in the previous step was the one that is shown by the red arrow above. You need to specify a second radius value that the spiral geometry will be created between these radius values in Autocad®.
There are three parameters that you can define for your spiral geometry in Autocad®;
- Turns: If you click on that option, you can enter the number of turns for your spiral geometry between specified radius values above in Autocad®.
- Turn Height: If you select this option, you can enter a value that will be the distance between each turn.
- Twist: If you click on that option in the ‘Helix’ command, you can specify your turning direction as;
- CW: Clockwise.
- CCW: Counterclockwise.
If you click on the ‘Axis endpoint’ option, you can obtain shapes like above in Autocad®.
The use of the ‘Helix’ command to create spiral geometries in Autocad® is very simple like above. Do not forget to leave your comments and questions about the ‘Helix’ command in Autocad® below!
