Hole

When the Create Feature/Hole function is first invoked, you will be prompted to pick one or more shell profiles to contain the holes. End the indication of profiles with Operation Complete. However, if one or more shell profiles are already selected, these are used. Next, the following form is displayed:

Figure 2:9. Form for creation and modification of holes in shell profiles

The Positions field: Where to place the holes. Repetition terms may be used in accordance with what is set in the Axis field.

The Axis field: Along which of the principal axes the positions of the holes in the group are placed.

The Type field: Standard means that the type of the hole is given in the field to the right in the form. Arbitrary lets you type in the name of an object from which the geometry of the hole is taken. Menu will bring up a menu after the form has been closed (using the Ok button). From this menu, you can select the type of hole, and the dimensions of the hole. Same As will give this hole definition the same hole type and dimensions as another group of holes, which you will be asked to indicate after the form has been closed.

The Mirrored toggle: Indicates whether the holes should have their normal appearance or be mirrored around the v axis. This field is irrelevant for all standard holes.

The Inclination Angle field: The angle of the hole geometry, given in degrees. If this field is left empty, the angle will be set to 0 degrees.

The Dist. From Trace field: Distance from the trace to the center of the holes.

The Ok button: Close the form and create or modify the group of holes.

The Cancel button: Exit the operation without creating or modifying any holes.

As mentioned above, holes can be selected from a menu dialog. The selectable holes can be customized. Further information about this can be found in Customizing dialogs in Hull.
