Curve: Create Helix(Wire)

Function

Create a spiral wire, which consists of a series of connected edges in space.

Call

Geometry > Curve > Create 3D > Helix (Wire)

<Helix>

Thread Direction

The selected direction vector becomes the centrical axis of a helix.
 

Select Axis

Select a reference direction (Datum Axis, Datum Plane, Face, Edge) for creating a helix.
2 Point Vector

Specify a reference direction from a vector which is defined by two selected points.
 

Start XYZ

Enter the 3D coordinates of a Start point [(ABS x, y, z)] of a helix. You may pick a point on the screen for entering coordinates. Entering the coordinates of a point can be much simplified by using the snap functions such as Vertex Snap and Grid Snap.
 

Pitch

Enter the increase in height corresponding to one complete revolution.
 

Turn

Enter the number of revolutions of a helix.
 

Taper Angle

Enter the angle of inclination of the side face of a helix relative to the reference axis.  The entered value and the actual inclination may not coincide since slight deviations occur in the process of generating the helix.
 

Name

Enter the name of the helix to be created.

When we enter coordinates using the mouse, the coordinates are automatically entered by a left-click on the desired point, without having to press the Apply button.  However, when coordinates are typed in, either the Enter key or the Apply button needs to be pressed.

Reverse

Create a helix in the opposite direction of the selected reference axis.
