An interactive tool of the type point to point or with direction can be switched to the other type, after calling, at any time. Clicking on one of the two buttons in the context bar starts the click process where either the end point for point to point or the direction for with direction must be re-defined. The original starting point is always transferred during type switch.

This function only becomes active if diverging from a master value The master value controls the values of the other objects in tools with several objects for interactive settings. If it is changed, all other values also change. As a rule, the master value is assigned to the first object selected when calling., further values have been set additionally or separately. This functionality is available in some tools only after option switch. zeroise values resets all additional or separate adjustments.

If, for example, the option adjust spread amount is set to adjust spread amount additive or adjust spread amount single, all spread amounts of all spread lines can be altered. If alterations have been made to subordinate spread lines, these alterations can be set to zero with zeroise values .

With click new, the entire click process is gone through again. The basic elements of the active function, e.g. points, lines, directions are queried one after another. You can decide separately for each basic element whether to retain it or set it again. A right click accepts the original position/ setting.

This way, individual base lines for draping can be retained with a right click and other base lines can be redefined.

The object selection remains intact with set new. It can be adapted via the function submit objects later .

The dialogue select objects opens where additional objects can be selected or previously selected objects can be deselected. With reset , all selected objects are deselected. At least one object must be selected for the button continue to be active. Clicking on this button terminates submitting.

do not pre-define staring and final distance: The starting distance and final distance arise. This means that the first and last spread line are equally considered during even distribution of all spread lines. In this case, their position cannot be altered interactively. The respective drag cursors and options are inactive.

pre-define starting and end distance: Starting distance and end distance are pre-set. Even distribution of the spread lines applies between the first and the last spread lines. The position of these two spread lines can be adjusted with the help of further options and drag cursors.

There are three variations for the distribution of the spread lines.

distribute along the base line: The distance between the spread lines is distributed evenly along the first and second base line. This option is particularly suitable for base lines with a regular course.

distribute from point to point: The distance between the spread lines is distributed evenly along a straight auxiliary line between the intersection first spread line/ base line and last spread line/ base line. This option is particularly suitable for base lines with irregular course.

distribute parallel: The distance between the spread lines is determined with the help of a rectangle. This rectangle is defined with the following points: intersection first spread line/ first base line, intersection first spread line/ second base line and intersection last spread line / first base line. The distribution of the spread lines is carried out on the auxiliary lines of this rectangle. If this variation cannot be constructed in a meaningful way, a distribution from point to point is done internally. The user is informed in the interactive environment.

Type from point to point

move spread lines along the base line: the move amount for the start point and end point of the spread line is calculated along the displacement line.

move spread lines parallel: the spread line is displayed as a parallel to the dashed base position. In this case, the move amount at the starting point equals the parallel distance to the base position . The move amount at the end point is an additional amount to the parallel distance.

Type with direction

move spread lines along the base line: the move amount for the start points of the spread line is calculated along the displacement line. The direction of the spread lines remains unchanged.

move spread lines parallel: the spread line is displayed as a parallel to the dashed base position. In this case, the move amount at the starting point equals the parallel distance to the base position . The move amount at the end point is an additional amount to the parallel distance.

There is a distinction between reference lines and spread lines. Reference lines are the lines which are generated when calling the tool. They are either defined as line from point to point or as line with direction . The click points of this line cannot be relocated. Their position can only be altered via set new . There is also the cutting line point at the intersection between the spread line and the cutting line for the type line with direction . These points also, cannot be interactively relocated.

relocate second spread line parallel from the first spread line: The second spread line is adjusted, not the last. It can be moved at a parallel distance to the first spread line. All subordinate spread lines are relocated respectively. The last spread line cannot be relocated interactively with this setting.

relocate last spread line from the first spread line: The last spread line can be moved at a parallel distance to the first spread line.

This option controls whether the drag cursor at the end of the master spread line is calculated additive or direct.

spread spacing at end additional: The drag cursor at the end of the spread line is affected in an additive manner to the spacing amount at the start of the spread line. In this case, the spacing amount at the end of the spread line equals the spacing amount at the start of the spread line plus the amount set for the end of the spread line.

spread spacing at end individual: The spacing amount at the end of the spread line is set directly with this drag cursor.

This option controls how the spread spacing is generated for the subordinate spread lines.

Adjust collective: the adjustments to the master spread line also apply to the subordinate lines. The spread spacing is set only for the master spread line.

Adjust additional: an additional drag cursor for the spacing amount appears at the subordinate spread lines. In this case, the spread spacing for the subordinate spread lines consists of the spread spacing of the master spread line plus the spread spacing adjusted for the subordinate spread line.

Adjust individual: The spread spacing can be adjusted individually for each subordinate spread line. The options spread spacing additional or collective are not active in this case.

This option controls whether a basic amount is pre-defined and distributed for spreading or if the spread spacing is pre-defined for each spread line. If the variation collective is active, the basic amount is initially distributed evenly to all spread lines. The possible additional amounts at the individual spread lines are then added.

Levelling

Levelling is only active if pre-define spread spacing collective is active and at least one base line is shaped as a curve. Only in this case is it possible, that the pre-defined basic amount for spreading may not be achieved exactly, due to the curve shape. It can then be re-adjusted optionally with the levelling drag cursor. This levelling is optional.

In the example, a basic amount for spreading of 159 mm is pre-defined for the second base line. Due to the curve shape, only 158 mm are achieved. The total length of the line and the achieved spread spacing are displayed in red. Via the levelling drag cursor, the total length of the line can be adjusted minimally so that the basic amount for spreading is achieved.
