Drawing a Helix

This command allows you to draw a profile on a 3D spiral axis. The axis of the profile is drawn using straight segments, as an approximation of a spiral. The accuracy of this approximation is set by the user.

This command will draw the following entities :

• The spiral model line
• The spiral profile
• A macro that connects the spiral profile to the model line, and calculates the twist angle of the profile.

To change the location and rotation of the spiral you need only move/rotate the model line.
To change the dimensions of the spiral itself, you need to use the Properties of the model line.
