Inclination Points

To define the exact inclination angle at specific points, up to 100 inclination points may be added to the shell profile. The location of each point is defined by the intersection between the profile trace and an object (seam, hull curve, plane, planar panel or another shell profile) or a principal plane. The angle is input in a similar manner as the angles at stiffener ends, that means, measured in a principal plane and given relative to the positive direction of one of the principal axis in that plane, as follows:

The fields in the form for inclination point are described below.

Figure 2:8. Form for handling of inclination points.

The Axis/Type field

The principal axis or object type to define the location of the current inclination point. If an object is selected interactively, the setting in this field is irrelevant.

The Position/Name field

The position (if principal plane) or object name defining the location of the current inclination point.

The Incl. Type field

Axis towards which the angle is measured. XT means that the angle is given in the X-Y plane, with an angle of 0 meaning in the positive direction of the X-axis and an angle of 90 degrees in the positive direction of the Y-axis. Similarly, YT means the Y-Z plane, 0 and 90 degrees being along the positive direction of the Y-axis and Z-axis, respectively, and ZT means the X-Z plane, 0 and 90 degrees being along the positive direction of the Z-axis and X-axis, respectively.

The Angle field

Angle against the principal axis set in the Incl. Type field.

The Add button

Add a new inclination point. The Position/Name and Angle fields will be blanked.

The Copy button

Copy the values of the current inclination point to a new one.

The Remove button

Remove the current inclination point.

The Remove All button

Remove all inclination points in the shell profile. This must be confirmed once more when the button has been pressed before the points are removed.

The Select button

Pick an object to define the location of the current inclination point.

The First button

Go to the first inclination point in the shell profile.

The Prev button

Go to the previous point in the shell profile.

The Next button

Go to the next point in the shell profile.

The Last button

Go to the last point in the shell profile.

The Ok button

Finish definition of inclination points and return the main shell profile form.

The Cancel button

Cancel the changes of inclination points since this form was shown and return to the main shell profile form.
