The Input Scheme

One input scheme should always describe one panel object.

The input scheme itself, being an ordinary text file, can be established and modified in different ways:

• Any text editor of the computer system can be used in a separate process to create or modify the input scheme.

• Planar Hull Modelling can on demand extract the input scheme from an existing panel for inspection.

• The input scheme can be created and written to a file when storing the panel if the default keyword SCHEME_CREATE is given in the default file.

An input scheme created outside Planar Hull Modelling can be used mainly in two functions. One is the "Scheme - Input" function where a scheme file is selected and then executed. Any errors will be displayed together with the scheme text in a dialog box.

Another way is to generate the scheme in the background via the "Scheme - Gen in background" function. In this case multiple schemes can be selected and a separate result file is created for each scheme. These files can be accessed via the Job Launcher.

When selecting an input scheme the logical name SB_SHIPSCH is used as the default directory to pick from.

A convenient way of creating input schemes for similar panels is to copy the text file with the input scheme and to modify it. The name of an input scheme can be selected quite freely.

An input scheme consists of statements according to certain syntax. Some of the statements describe general panel qualities while others define component groups. The component statement in the scheme defines a component group in the panel object.

The design language of Planar Hull Modelling is described in detail in Design Language of Hull Modelling.

Normally the panel is generated into its surrounding structure, for example, into the web frame, which it is part of. This environment should be displayed on the screen.

However the panel can also be generated isolated as a SEPARATE panel. This happens when the "Scheme - Input" function is used stating from an empty screen with no drawing opened.

When the Input Scheme is created from the panel, the following default parameter will have an impact on how the Input Scheme will be created:

The environment variable SBH_UPD_NO_IN_SCH has also an impact on how the Input Scheme will be created. If set, the part number (for example NO, CNO) will NOT be written to the scheme.
