Overview

The shape of waterline endings and frame feet can be defined in PACE framework, using the same concept of the end surface that is used in the Lines framework. The general procedure for defining waterline endings and frame feet using end surfaces in PACE is as follows:

• An end surface is created at an end of the hull form. This is defined by describing the desired distribution of radius and eccentricity along the length of the profile curve.

• The waterlines (and optionally sections) are modified so that their ends take on the shape of a segment of the planar slice through the end surface.

• The user alters various parameters that control the shape of the end surface, and how much of the planar slice is used in an iterative way until a satisfactory result is achieved.

The key elements of the end surface functionality are shown in Figure 3:87 below.

The following sections describe the essential operations of the functionality. They are presented roughly in the order that would be followed during a hull design exercise, but this is not enforced, and any stage can be revisited at any time.
