Creating Threads (No Reference)

This task will show you how to create a thread without a reference. In this particular case, you will apply a thread to a hole.
Open the Brackets_views06.CATDrawing document.
  1. Click the Thread icon from the Dress-up toolbar (Axis and Threads sub-toolbar).

You can also multi-select holes before clicking the Thread icon.
Activating this command displays two options in the Tools Palette which is automatically displayed:
  • The Tap type option , which is activated by default.
  • The Thread type option .
  1. Select the Thread type option .

  2. Select the hole (or circle) to which you want to apply the thread.

The thread is created.

  1. Select an axis line manipulator and drag it along a direction. Thread axis lines are modified symmetrically.

If you want to move only one axis line, hold on the Ctrl key while you are dragging the manipulator.
If you delete the thread axis line, the external circle is also deleted and vice versa.
  • The thread that appears on the hole is assigned a standard radius and representation (compliant with the selected standard).
  • When creating a thread on a generative view, a message will be displayed if the thread cannot be associative to the 3D.
