Create Feature - Hole

Purpose:

To create one or more holes in a number of shell profiles.

Prerequisites:

A shell profile (and thus at least one shell stiffener) must exist.

Instructions:

• In create mode, the user must indicate one or more shell profiles in which to create the holes, and then give a hole definition. If any shell profiles are already selected, they will be used as input to this function.

  The user must enter the position of the hole or holes in the Positions field. The hole type may be entered in the form, selected from a list or copied from another hole (Same As).

  Alternatively, the hole may be generated from an arbitrary two-dimensional curve object (Arbitrary). A distance from the shell profile trace to the center of the hole may be set, as well as the inclination angle of the hole.

• In modify mode, the user may change the hole definition. The modification will only affect the holes in the selected shell profile. If holes have been created in several profiles at once, the hole definitions in the different profiles must be changed one at a time.

Options:

None available.

Result:

• In create mode, holes will be created in the selected shell profiles. The Store function may be used to store the shell profile with the new holes on the hull structure data bank.

• In modify mode, the shell profile will be updated with the new hole definition. To make changes permanent, Store must be used. Using the Skip function before the shell profile has been stored will undo the changes.
