An arbitrary restricted line can be added for use as a marking line. A typical example is to use such a line to align two plate parts in a slender panel, for example, a curved side web.

MAR, U1=<coord>, V1=<coord>, U2=<coord>, V2=<coordinate> U=<coord>, V=<coord>, T=<angle> | X=<coord> | Y=<coord> | Z=<coord> [, TYP=<type> ] [, {P|S} ] ; |
Description
|
U1, V1 |
Defines the starting point of the line. |
|
U2, V2 |
Defines the ending point of the line. |
|
U, V |
Defines the starting point of the line. |
|
T |
Defines the angle of the line. |
|
X, Y, Z |
Defines the axis. |
|
TYP |
Defined type of marking. |
|
<type>::<integer> |
|
|
P | S |
Symmetry of the marking. P only valid portside. S only valid starboard. |
When creating this statement interactively:
-
For two point uv lines the user points at the starting and ending point of the line.
-
For uvt lines the user points at the starting point and chooses the angle.
-
For axis lines the user points at the point of axis.
By the default parameters MARK_LINE_TYPE and MARK_LINE_COLOUR in the default file of Hull Modelling the line type and the color of the marking lines can be controlled.
