Using Clash Manager with the Laser Model Interface

When used in conjunction with the Laser Model Interface, Clash Manager employs a range of methods to highlight clashes with laser models. The result will depend on the functionality that has been implemented by the laser model vendor, but can include showing an outline box around the cell of the laser model that contains the clash, showing the portion of the laser model within that cell in a higher visual density than the surrounding region, and highlighting the content of that cell.

Clash Manager will automatically initialize a connection to the laser model driver via the macro des-pclam-lmi-init.pmlmac which is provided in the Model Manager pdmsui/dflts folder for local customization to suit the laser model software installed at the client site. LMI initialization is invoked by Clash Manager during a background Desclash run when an XCELL is encountered in the obstruction list, and also on first encountering an XCELL during viewing of clash groups in the interactive Design session.

The same macro can also be used to set the Desclash run to test with Cells or ExactGeometry. The ExactGeometry setting will generate more accurate (and thus fewer) clashes, but at the expense of increased runtime. The ExactGeometry option may not be supported by any particular laser model software vendor.

Please note that laser models are not supported in Marine prior to version 11.6.SP2.

Users' attention is drawn to the implications for licensing of the laser model software when using Clash Manager. If an interactive Design session and a background Desclash session occur simultaneously there is the potential for Clash Manager to request two concurrent laser model connections.
