'line' <name(char<9)>|'!' <p1> <p2> <cp|seq> <div> [<bias>]This keyword is used to define or redefine a line. A line depends on points. A line can only be defined if the necessary points are already defined. Attention: The points p1 and p2 must not lie on the same location. There are three different types of lines available. The straight line

The bias is used to change the distances between successive nodes:
line l1 p1 p2 4 1.1
The bias of 1.1 means that each successive node is 1.1 times farther away. Only if a bias is given can the division be greater than 99.
ATTENTION: If the user does not provide a bias only the last two digits of the given 'division' are used to define the division itself. The leading digits define a bias. But in a different way as explained above. Here the bias defines the length increase between the first and last element on the line. If the bias uses more than one digit in front of the division, the number has to be divided by a factor of ten to get the bias (10130 means a bias of 10.1 and a div of 30). A negative number changes the direction of the bias:
line l1 p1 p2 -404
The number -404 specifies a division of 4 with a bias of 4 but the first node distance is 4 times longer than the last.
