As there may be a need for additional reference marks along the boundary of a panel, the interactive modelling function has been supplied with a facility for manual setting of GSDs.
Syntax
|
MAR, LIM= <lim_no>; [, M1=<distance> ] [, TYP=<type> ] [ {P|S} ] ; |
Description
|
LIM |
Defines the limit along which reference marks should be added. |
|
<lim_no>::=<integer> |
|
|
M1 |
Distance from the limit. |
|
<distance>::<float> |
|
|
TYP |
Defined type of marking. |
|
<type>::<integer> |
|
|
P | S |
Symmetry of the marking. P only valid portside, S only valid starboard. |
The GSDs are placed along panel limits and are oriented towards one of the three principal axes.
The spacing between GSDs in the direction of the y- and z- axes is defined by the keyword INTERVAL in the file assigned to the environment variable SBH_GSD and evaluated from the center line and the base line, respectively. Reference marks in the direction of the x-axis are placed at frame locations.
The evaluated GSDs are displayed during modelling but will not be part of the drawing.
Distance is moving the marking always inside the panel.
Type is a simple number.
