Creation of Hull Marks

Field Name

Description

Hull Mark Name

Name of the resulting hull mark object. Click the Auto button to automatically set the name to the hull text name followed by a _S suffix.

Hull Text

Name of the hull text to be projected. Click the New button to switch to defining a new hull text.

Hull Mark Type

Method for production of the hull mark:

• Cont. Weld - hull mark by weld (solid line)

• Weld Pattern - hull mark by weld pattern as defined in the hull text

• Plate - hull mark as plate parts

Surface

Surface onto which the hull text should be projected.

Panel

Name of planar panel on to which the hull text should be projected.

Note: Hull marks on knuckled panels are not supported.

Perpendicular

When Perpendicular is checked, the hull text is projected along the normal of the surface or panel to minimize distortion. For a hull mark placed on a surface, the surface normal at each individual character or symbol in the hull text is used for the projection direction.

Note: The Looking from and Looking towards settings still determine the placement of the reference point of the hull text on the surface or panel.

If Perpendicular is not checked, the hull text will be projected along the Looking towards direction. The resulting hull mark may be distorted in case this direction deviates from the plane or surface normal.

Reference Point

Point on the hull text to be used for positioning of the hull mark:

• Left

• Middle

• Right

The selected point is the one placed in the Looking from point before projecting the hull text onto the panel or surface.

This allows for easy positioning of for example, a ship name on both the PS and SB sides.

Looking from (X Y Z)

Positioning of the hull text in space before projecting it onto a panel or surface. The point is given as three coordinates, separated by blanks or commas. FR and LP terms may be used.

The given point will be used for alignment of the lower left corner of the first character (Reference Point set to Left), the lower right corner of the last character (Reference Point set to Right) or the midpoint of those two (Reference Point set to Middle).

Looking towards

Projection direction of the hull text. Any can be used for projection in an arbitrary direction, specified in the X Y Z field. Only a hull mark placed on a planar panel can be projected in an arbitrary direction.

The projection direction also determines the main orientation of the hull text before projecting. The hull text will have a horizontal main orientation if looking along the X or Y axis, or be oriented along the Y axis if looking along the Z axis. For an arbitrary looking direction (that means, not along a principal axis), the rule for the closest principal axis will apply.

From its main orientation, the hull text may be rotated around the projection line before the projection takes place (see Rotation Angle).

(X Y Z)

Vector specifying an arbitrary projection direction. Relevant only if Looking towards is set to 'Any'. The components of the vector should be separated by blanks or commas.

Rotation Angle

Angle by which the hull text should be rotated around the projection line before projection. A positive angle means a counter-clockwise rotation when looking in the projection direction.
