The parallel lines can be beside, below or on top of each other.

The manner in which the lines are arranged is governed by the line you select in the Ref. line column. The position of the other lines is based on this reference line.

You can lay down the criteria defining how two parallel polylines are joined.

• Do not join
• Lines that have the same consecutive number are joined.
• Lines that have the same color are joined.
• Lines with the same name are joined.

You can enter up to 9 parallel 3D lines.

The distance between the lines can be modified to suit your needs. You can define the direction in which this distance is applied in the Arrangement area. This setting applies for all the lines.

The manner in which the lines are arranged is governed by the line you select in this column. The program creates all the other lines based on the reference line specified here.

Note: To enter a line that is at a specific distance from existing points (e.g. wall edges), enable the check box displayed at the top in the list.

You can enter names for the lines; the consecutive numbers are predefined.

You can assign a color to each line.

You can define the distance between two lines.

The distance between the lines is always applied in the direction specified in the Arrangement area.

• The number of lines that make up the polyline you want to join with an (existing) polyline must not exceed the number of lines that make up this (existing) polyline (= the polyline you click first).
• Each line of the first polyline must match a line of the other polyline. You can define the criterion that is to be fulfilled in the Join based on area.
