Creating Center Lines (No Reference)

This task will show you how to apply a pair of center lines to a circle or an ellipse.
Open the Brackets_views06.CATDrawing document.
1. Click the Center Line icon from the Dressup toolbar (Axis and Threads sub-toolbar).

2. Select a circle.

Center lines are automatically applied to the circle
.

3. Click in the drawing to confirm the creation and select the center lines.
4. Use manipulators to modify center lines size.
 
  • You can apply this scenario to an ellipse.
  • When creating a center line on a generative view, a message will be displayed if the center line cannot be associative to the 3D.
  • The center line is not associative in the following cases:
    • When the corresponding 3D geometry cannot be accessed or loaded (non-existing parts, parts not loaded, and so on).
    • When the view is not up-to-date.
    • When a complex 3D edge results in several 2D circular arcs in the view as its 2D result.
      For example, see the image below:
