Creating Threads With a Reference

You can create a thread with a reference, either circular (circle or point) or linear (line). For example, you can apply a thread to a hole with a line as reference.

  1. From the Annotation section of the action bar, click Thread with Reference .
    Tip: An alternative method is to select several holes and then click Thread .

    In the Tools Palette, the following options are available:

    • Reference Tap , which is activated by default.
    • Reference Thread .
  2. Select Reference Thread .
  3. Select the hole (or circle) to which you want to apply the thread.
  4. Select a reference line.

    The thread is created according to this reference.

  5. Select an axis line handle and drag it along a direction.

    Thread axis lines are modified symmetrically.

    Tip: To move only one axis line, press Ctrl + drag the handle.
    Important:
    • When creating a thread associated to interactive (2D) geometry, the 2D circle radius is computed according to the following formula:

      Thread Radius = 2D Circle Radius * 1.125mm +0.25mm.

      The Metric Thin Pitch or Metric Thick Pitch defined by standards being different, these cannot be applied.

    • When creating a thread associated to generative geometry, a message is displayed if the thread cannot be associative to the 3D area. In this case, the thread is neither linked to the 3D area nor to 2D geometry. For example, a non-associative thread with a reference line is not updated when the reference line is moved.
