To Create a Reference Zone
1. Click Format > Reference Zones. The REF ZONES menu appears.
2. Click Create to create a reference zone. You are asked to specify a rectangular area for your reference zone by selecting corner points. If this rectangular area overlaps an existing reference zone, the reference zone you create is truncated. The ZONE DIR menu appears.
3. Click Horizontal in the ZONE DIR menu if you want the division lines in this reference zone to be displayed horizontally. Click Vertical if you want the division lines to be displayed vertically.
4. Enter the new grid spacing of the division lines, a starting index, and a delta (index difference between the lines). The starting index can be a negative number. Horizontal division lines are used with a default grid spacing of 0.25, a starting index of 10, and a delta index of 10. The ZONE SETUP menu appears.
5. Select an appropriate command from the ZONE SETUP menu.
◦ Mod Boundary—Click a new area of your drawing to use as a reference zone. Division lines which no longer fit in the area you have specified are deleted. New division lines are not created if the new area is larger than the old area.
◦ Spacing—Enter a new spacing for the division lines in your reference zone. This value should be entered in drawing units.
◦ Renumber—Specify a new starting index and a new delta. The reference zone is modified accordingly. The starting index can be a negative number.
◦ Insert—Add a division line to your reference zone. When selected, you are prompted to select a point in your reference zone where you want the division line to be placed and to enter an index for this division line. A new division line is placed parallel to existing division lines at the location you specified. This option does not effect the current numbering of the division lines.
◦ Remove—Deletes an existing division line and its index. This option does not effect the current numbering of the division lines.
◦ Mod Index— Lets you modify the index of one division line. When selected, you are asked to choose the division line whose index you want to modify. You are then prompted to enter a new index. This option does not effect the current numbering of the division lines.
◦ Label Pos—Change the position of all the labels in the reference zone. When selected, the Offset Side menu appears, allowing you to indicate the side of the reference zone where you want the index labels to appear and the index label’s distance from the edge of the zone.
If the reference zone has vertical division lines, the Offset Side menu has the following options:
◦ Top—Place all index labels on top of the reference zone.
◦ Bottom—Place all index labels on the bottom of the reference zone.
If the reference zone has horizontal division lines, the Offset Side menu has the following options:
◦ Left—Place all index labels to the left of the reference zone.
◦ Right—Place all index labels to the right of the reference zone.
6. Click Done/Return first in the ZONE DIR menu and then in the REF ZONES menu.
