About Modifying Witness Lines
When a dimension is placed on a model, it leaves a gap between the model and the witness line. The Detail option witness_line_offset controls the actual size of the gap. Sometimes this gap is not visible on a drawing. However, it becomes noticeable when you plot the drawing. To see how the drawing will look when you print it, click File > Print > Print, and click Preview.
A witness line can have both jogs and breaks. When you add jogs to a witness line that already has breaks, the breaks that were created as simple breaks appear on the first unjogged segment of the witness line. If a witness line has dimension breaks, jogging a witness line relocates a break to a new intersection point.
You can edit witness lines in the following ways:
• Create parametric or simple breaks in dimension witness lines and in leader lines of notes and symbols.
• Resize the gap by dragging the end handles. You can simultaneously clip several dimensions that have the same orientation so that their witness line endpoints all align. Using multiple selection, you can manipulate witness lines in the following ways:
◦ Clip both witness lines of a dimension at the same time.
◦ Clip the witness lines of many dimensions at once. When you pick on the witness line of each dimension, the system moves each of the endpoints together.
• Erase and resume witness lines.
• Skew witness lines.
• Add jogs to and delete them from linear (standard and ordinate) and angular dimension witness lines, note leaders, and symbol leaders.
• Create and modify angular, diametrical, radial, and linear dimensions with and without an elbow.
