Spatial Maps :

Spatial maps of the model are based on the obstruction limit boxes surrounding each Design element, rather than using fully detailed geometric representations. The spatial maps allow faster data access, and they are used for tasks such as clash detection where fast data access is required and where the simplified representation is adequate.

Spatial maps are maintained automatically as the design model is updated, but may need to be rebuilt explicitly if the Catalogue data, from which the map geometry is derived, is changed.

Also in DRAFT Module the ADD ... WITHIN variation of the ADD command uses the PDMS spatial map. The spatial map is a simplified geometric representation of the design model

Note If the spatial map is not up-to-date the list of elements generated may not be correct. The ADD ... WITHIN method may produce very long Id Lists. These are liable to become out-of-date as elements are added to, and removed from, the Design databases. Better results may be yielded by setting the IDLI’s LIMI attribute (see Command Summary section at the end of this Chapter) to define the required volume and only ADD the relevant SITEs and ZONEs to the Id List.

Updating Spatial Maps:

Lets you update existing spatial maps to take into account all design and catalogue changes which have taken place.
