Control of Marking Gap at Holes

Description

When creating plane panel parts via the Plane Part Generation (ppanparts) functionality, the user has the possibility to set a default parameter value, MARKGAP, that controls the distance marking lines will be cut off at the outer contour of the plates. If a marking line ends at (or crosses or is close to) a hole, no check on any marking gap has been done so far.

However, there is one exception. Marking lines defined via the MARKING statement in the Hull Modelling will be cut off at holes using the parameter MARKGAP.

Because of possible plate damage when burner cutter crosses a marking line, the possibility to reduce other type of marking lines have been implemented.

Three new default parameters have been entered into the ppanparts function. The names of the parameters are:

REDUCE_MARKGAP_OF_STI_AT_HOLES,

REDUCE_MARKGAP_OF_PLANE_AT_HOLES,

REDUCE_MARKGAP_OF_PANEL_AT_HOLES,

By giving REDUCE_MARKGAP_OF_STI_AT_HOLES, marking lines of the mould lines of stiffeners (default parameter STI must be given) will be checked for and reduced if the conditions mentioned above is fulfilled.

By giving REDUCE_MARKGAP_OF_PLANE_AT_HOLES, marking lines of the reference planes (default parameter REFPLANE must be given) defined in Hull Modelling will be checked for and reduced if the conditions mentioned above are fulfilled.

By giving REDUCE_MARKGAP_OF_PANEL_AT_HOLES, marking lines of abutting plane panels (default parameter PAN must be given) will be checked for and reduced if the conditions mentioned above are fulfilled.

Benefits

Enables the user to control the extension of marking lines around holes.

Compatibility Constraints

None.
