This sub-syntax may be used to define a topology point by reference to the corners of the current panel or any other given panel.
Syntax
|
<at_corner>::= ,COR = <corner_No> ( 1 ... 25) [, <panel> [, REFL] [,SID=<dir>] ] [, M1=<forw_move>] | [, M2=<backw_move>]
<corner_No>::=<integer> <forw_move>::=<backw_move>::=<number> <panel>::=<name> |
Description
|
COR |
The number of the corner. |
|
<panel> |
Name of the panel the corner(s) of which should be used. If left out the corners of the current panel will be used. |
|
REFL |
The corner point will be reflected in the center line plane of the ship. |
|
SID |
If the corner is on another panel which is intersected by the current one, SID indicates from which side of the "other" panel the corner point should be fetched. If left out it is supposed to be in the mold plane. |
|
<dir>::= AFT|FOR|PS|SB|TOP|BOT |
|
|
M1 |
Defines a move in the forward direction of the outer contour from the given corner. The move will be along the contour of the panel in which the corner is indicated. |
|
M2 |
Defines a move in the backwards direction. |
The primary direction will be calculated as the direction of the tangent after the corner, the secondary as that of the tangent before the corner in the negative direction of the contour.
In case of a move the corresponding direction will be calculated in the position of the resulting point.
The picture below illustrates the meaning of the parameters in this case.
