HELIX IN 3D

Now let’s we discuss how helix is working in 3D.

A 3d window of auto cad is the window in which 2d sketch are converted into the 3d.

It contains the various modules like Part modeling, Surface modeling, and Wireframe meshes, rendering etc.

To learn how it is work lets we follow the following steps:-

Open the 2d window of the auto cad.

Go to draw bar and select the helix tool.

Now enter the centre point of the helix(0,0)

Enter the radius of the first circle of the helix.

Enter the no of turns of spring.

Enter the height of spring.

Now, enter the second radius of the helix.

Now 2D sketch of helix is ready.

To convert the 2d frame of helix into 3d we have:-

• Open 3d window of auto cad.
• Keep the helix in top plane. (Make sure that you sketch the 2d helix in front plane).
• Now took the circle command and draw a circle at right side of the turn of helix (keep note that the dia of circle is not more than the pitch of helix.
• Now go to sweep toolbar of the 3D window and select the circle of helix as a profile.
• Select helix as a path
• Automatically a 3D spring is created.
