Edit the mark length, line style, color, and placement details. You can also set the default line width on the Marks tab in the Preferences dialog box. 

Note: Set the default line width on the Marks tab in the Preferences dialog box.

Size 

• If you select Fixed Length, specify the Length of the line mark and the Angle (number of degrees) by which it should be rotated.
• Select Vertically centered or Horizontally centered if you require a straight, centered line mark of variable length that is automatically sized to fit the Anchor to selection. 

Style

Select the line type (solid, dotted, or dashed). 

Anchor

For fixed-length line marks, you can select any of the nine points in the Anchor to diagram, and then specify any vertical and horizontal offsets to be applied to the selected anchor point.

For variable-length marks, the anchor points are selectable vertical or horizontal lines, corresponding to the selected Size centered option.

• For vertically centered marks, you can apply a horizontal offset, and specify how much vertical margin to allow. (Applying a vertical margin shortens the line mark.)
• For horizontally centered marks, the opposite applies. 

Horizontal, Vertical

Type the amounts of horizontal and vertical space to allow between the mark and component anchor points.
