Parallel
With the
Parallel 
tool, one or more parallels are constructed. The parallel constructed first becomes the master parallel, all further parallels are subordinate parallels. This is relevant when switching options as the subordinate parallels depend on the settings of the master parallel.
The distance value can be altered simultaneously for all parallels set in one cycle. Alternatively, through an option switch, individual parallels can be assigned an additional distance or the distance for each parallel can be set separately.

For certain construction processes, it is necessary to define what is the start and the end of a line. The line receives a direction.
Grafis supports the user with the so-called "right principle cursor" which additionally has a direction indicator. The parallel is constructed on the side of the click.
The parallel constructed first becomes the master parallel. It is relevant during option switch as the other parallels depend on it. - if required, adjust the parallels interactively
functions of the context bar
zeroise values 
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 parallel adjustment is set to adjust parallel additional or adjust parallel individual, the distances of all parallels can be altered. If alterations have been made to subordinate parallels, these alterations can be set to zero with
zeroise values
.
The function
zeroise values
also becomes active if the line ends option is set to adjust parallel additional at line end. With this function, it is possible to create an non-parallel line run. If the line ends of oner or more parallels have been altered, they can be set to zero with the function
zeroise values
.
set new 
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 parallels can be retained with a right click and other base lines can be redefined.
Options
Option parallel adjustment
This option is only active if at least two parallels have been set.
adjust parallel collective: With this option, a drag point is active on the parallel set first. Here, the master value for the distance of all parallels is adjusted. The drag point at the tip of the arrow can be used to change the drag point for the distance value to the other end of the line.
Adjust parallels additional:
With this variation, an additional drag point becomes active at the start of each subordinate parallel. Based on the master value of the first parallel, additional distances can be adjusted. The dependence on the distance of the master parallel remains intact. The drag point for the distance value can be reversed for each parallel.
Adjust each parallel seperately:
With this variant, each parallel is adjusted individually. The dependence on the distance of the master parallel no longer exists. The drag point for the distance value can be reversed for each parallel.
Option line end
With this option, an additional distance can be set at the line ends of the parallels. The second variation activates the relevant drag points at the end of the parallels.
In the area Change in length, the line can be extended or shortened at these drag points.
Option line attribute
This option relates to the base lines selected when calling the tool, not to the new created parallels.
These lines can be assigned the attributes 'dashed line', 'stitch line' or 'invisible'.
