Loftbook (Table of Offsets)

The Loftbook function allows the user to generate a table of intersections between specified groups of orthogonal curves and 3D curves. The user can choose to intersect all curves of a particular type or curves on specific layers.

The output may be specified as a formatted report or as a simple text file. For a text file, the user can control the page width, number of lines per page and line spacing.

By using the Units/Axes dialog the user can control whether the Section curve identifiers are output as Station numbers, Frame numbers or X distances. X distances output within the body of the table are output as meters, millimeters, depending on the current units settings.

As an example, we will create a simple loftbook for the current datastore.

Create a Loftbook

1. The Loftbook dialog is accessed via the icon.

   The loftbook will be output as a formatted report.

2. To define the curves to intersect:

   1. select Waterlines from the Cross pulldown and Sections from the With pulldown then click the Add button.

   2. Select Buttocks from the Cross pulldown and click Add.

   3. Then select Waterlines from the With pulldown and click Add.

      For the layout of the table, the curves from the Cross pulldown will appear as column headers and the With pulldown as row headers.

      

3. Before generating the loftbook, select the Echo toggle,

   This will print a message to the Output window indicating the curves being intersected.

4. To output the loftbook, select Apply.

   The loftbook is then displayed in a Report View.
