Design and Drawing Databases

1. Design Database
Design Database Contains Data which holds information about 3D elements created in Design Module. It contains elements in particular hierarchy with all attributes of that element. User having read-write access to Design Database can create or Modify content of that database.
SITEs created in Design Module are linked to particular Design Database. One Design Database can own one or several sites depending upon requirement.

Design Database Stores Data created using following applications in Design Module :
1. Equipment
2. Pipework
3. Cable Trays
4. HVAC Designer
5. Structures
6. Design Template

Typical Hierarchy of Design Database:

Note : Equipment can directly own Primitives and Nozzle

Similarly, hierarchy for Structural Elements

Fig. 2 Design Database Hierarchy

In Design Database, SITE and ZONE are top most hierarchical Elements which are common for all elements.

2.    PADD Database

PADD – Production of Annotated and Dimensioned Drawings
PADD(Draft) Databases are used in Draft Module, which Holds data about Pictorial content of Drawings and Dimensional Information. it also holds information about Draft setup such as Sheet Libraries, Symbol Libraries, Isodraft Libraries, Label Libraries, Style Libraries etc.
Similar to Design Database, It also holds elements in Particular hierarchy.

3.    ISOD (Fabrication or Spooler) Database
Fabrication or Spooler Database is used in Spooler Module. This database holds Information about Spool Drawings such as spools, Field, welds, joints, etc., which is used for fabrication purpose.
