INTRODUCTION 1
SOME GENERAL ISSUES

Are made at CERN and in worldwide design offices

Must be stored and easily accessible

Must be managed according to various schemes

INTRODUCTION 2
WHAT IS CDD ?
CDD  CERN Drawing Directory
Drawing management tool
Oracle based application
 Stores plot files & drawing meta-information
 Supports various CAD tools
 Different drawing numbering systems
 Different management rules
 In production since may 1996
 More than 160.000 registered drawings


INTRODUCTION 3
INTERFACE & FILES

A limited interface exists using Oracle Forms

Main interface is

HPGL format used for drawing plot files

BASIC NOTIONS 1
NUMBERING SCHEMES
Drawings are numbered following conventions
Drawing system notion
 CDD supports several drawing systems :

EST/LHC : 12 char
 LHC Exp : 12 char
 SL-PO
: 12 char
 ST-CV
: 12 char
 ST-CE
: 16 char

LHCXDEMA0001
ATLXELMX0001
LHCEBD__2000
LHCW31830001
LHC-BIS100401018
Old SPS & LEP systems are still available

BASIC NOTIONS 2
ACCESS MANAGEMENT
Drawing access (registration, update, control) must be managed
Drawing subject notion
 Example (EST/LHC drawing system) :

Project +
Equipment
=
Subject
L HC
XDEMA
L HCXDEMA
ACCESS
Subject access is
granted by groups of
users and managed by
system administrators
CERN Drawing Directory - CDD - CERN EST/ISS
note
Group a
User a.1
User a.2
User a.3
NO ACCESS
Group b
User b.1
User b.2
BASIC NOTIONS 3
DRAWING NUMBER
Each drawing must have a unique and public number
CDD provides the drawing number
 Example (EST/LHC numbering scheme) :

Subject
+ Sequence Number
L HCXDEMA
0 0 0 1
LHCXDEMA0001

BASIC NOTIONS 4
DRAWING REVISION
The evolution of a drawing must be managed and controlled
CDD handles drawing versions
 Each version has got a revision index
 The history of the drawing is kept

CERN Drawing Directory - CDD - CERN EST/ISS
BASIC NOTIONS 5
QUALITY CONTROL
Each version must be controlled before being archived

Various control rules are implemented :
Lowest level
Highest level
design office responsible
(but the designer)
only one signature
(designer allowed)
note
Rules are managed by
system administrators
