Control on Application Level

The control of the application as a whole may take place in several different areas.

One of those is of course the environment, that means, data banks, directories, This is all documented and described together with the tools for project management.

Another matter of general importance for a project is to select names for the current project, to set up rules for frame numbering and spacing, ditto for the longitudinal spacing and numbering,

These matters are normally handled by the module for initialization of a hull project, called inithull.

Finally there are some means of controlling the overall behavior of Hull application, mainly related to how it identifies, handles and stores parts that are symmetrical with respect to the center line or specific for portside and starboard, respectively. This control takes place via a number of environment variables and the main purpose of this paragraph is to give a detailed description of their use and effect. The environment variables are normally supposed to be defined in the project file of the current project. The use of these variables is not always independent of each other as the description below will illustrate.
