CERN Drawing Directory - CDD - CERN EST/ISS
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
CERN Drawing Directory - CDD - CERN EST/ISS
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
CERN Drawing Directory - CDD - CERN EST/ISS
INTRODUCTION 3
INTERFACE & FILES
A limited interface exists using Oracle Forms
Main interface is
HPGL format used for drawing plot files
CERN Drawing Directory - CDD - CERN EST/ISS
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
CERN Drawing Directory - CDD - CERN EST/ISS
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

DRAWINGS FROM CERN
Must follow the CERN standards
title block
fonts...
Native files accepted
AutoCAD
Euclid
Pro-Engineer
HPGL
Various checks are done during the archiving
process
CERN Drawing Directory - CDD - CERN EST/ISS
BASIC NOTIONS 9
DRAWINGS FROM OUTSIDE CERN
Can follow the CERN standards
HPGL files recommended
Institute number can be used
registered as “external reference” information
retrieval based on this number is possible
Special stamp can be defined
added during the archiving process
require a blank zone in each drawing
indicates CDD information (CDD number…)
Upload feature helps for file transfer
drawing by drawing
ftp recommended if too many drawings (!)

CDD FEATURES 5
QUALITY CONTROL
Validated by electronic signatures
One click on this
link creates the
electronic signature

ARCHIVING
Drawing Information Page
Source Address :
the native file must
be put there to
be archived
These two
signatures
triggered the
archiving process
After batch process
the drawing is
archived
