Marine/Design Limitations

Attribute data from .drv files is not transferred to the Design database.

The data generated can be clash-checked in DESIGN. However, the DGN data cannot be thoroughly checked for clashes within itself unless you create a separate EQUIpment, VOLuMe or STRUcture for each primitive.

Large amounts of data are generated for both Marine/Design and Review. This is because neither Marine/Design nor Review can store non-standard primitive shapes economically. This, for example, may cause problems with the DRAFT module. This module can not cope with a large number of primitives under a significant element (such as an Equipment, Volume, Structure, Polyhedron etc). There is a limit of 4096, but performance will be severely degraded with more than 500. You may use the GROUPP command to limit the number of primitives in an element in PDMS.

Specifically, you are advised to read large Design macros by entering DESIGN in dev tty mode and then use the TRACE OFF command before you run the design macro.

Attribute data from .drv files is not transferred to the Design model.
