Place a centerline midway between two lines


  1. Choose Home tab→Annotation group→Centerline .

    Note:

    In a model, this command is also available on the PMI tab.

  2. On the Centerline command bar, select the Line centerline type.

  3. From the Placement Options list, select By 2 Lines.

  4. Click the first line (A), and then click the second line (B).

    The centerline appears midway between the two lines (C).

Tip:

  • If you select the By 2 Points option from the Placement Options list, you can place a centerline in one of the following positions:

    • Between two key points on an element. You click two points (A, B) and then click to place the centerline (C).

    • Between two center marks.

    • In free space.

  • You can modify a centerline by dragging the edit handles on the centerline. You can also cut, copy, or paste a centerline. When you drag the centerline away from the element it is attached to, the centerline no longer has a relationship to that element.

  • You can change the appearance of the centerline by changing its properties in the Center Line & Mark Properties dialog box. Select the centerline and then click Properties on the shortcut menu.
