Use it!

(3D only) Used to place a helix (3D B-spline curve).

Tool SettingEffect
Thread

Can be right or left.

Axis

Sets the direction of the helix's axis.

  • Points
    • — Lets you define the direction of the axis graphically.
  • Screen X, Y, or Z
    • — Sets the direction of the axis parallel to the Screen X, Y, or Z axis.
  • Drawing X, Y, or Z
    • — Sets the direction of the axis parallel to the Drawing, or DGN file's X, Y, or Z axis.
Orthogonal

If on, the helix is orthogonal.

Top Radius

If on, sets the second radius (step 5 below).

Base Radius

If on, sets the first radius (step 3 below).

Height

If on, sets the height (step 4 below).

Pitch

If on, sets the pitch.

Tolerance

Sets the tolerance.

To place a helix
  1. Select the Place Helix tool.

  2. Enter a data point to define the Base end of the axis.
    If all constraints are on and Axis is set to anything other than Points, the helix is displayed dynamically and you can enter a data point to accept the helix.

  3. Enter a data point to define the beginning of the helix and the first (Base) radius.

  4. Enter a data point to define the other end of the axis.

  5. Enter a data point to define the second (Top) radius.

  6. Accept the helix.
