Drawing data DRID Source tool DRAWING Source address Titles Design Office Version data VERSIONS Drawing data se Index Designer Format XX Date In fact drawing is only an abstract concept which englobes all its versions and some common information for all of them The physical realisation of a drawing the object paper we obtain at the end that can be seen is always a given version of the drawing A drawing will always be identified by its drawing number A given version will be identified by the number plus an index e g LHCLQAO_0001 AA will be the second version of that drawing The index of a drawing will indicate the version we are dealing with it starts with 4 7 first version and grows AA AC etc The use of is only an internal CDD representation not used in the title block This permits easy queries typing means I want the first version and only this 93 A drawing is created once and with it its first version index is created automatically Later several versions of the same drawing can be created always respecting the data already defined for the drawing Some drawing data can be changed under specific conditions e g if the drawing has never been archived In the same way some characteristics of a given version can also be changed When new version is created all previous versions are frozen the last
6. Drawing subjects and drawings are related to one or several objects by their own definition see section 1 For instance if you consider the drawing system EST LHC the subject LHCXELMX is linked to the equipment XELMX by definition This makes all drawings of that subject e g LHCXEMLX0001 also linked to that equipment This is due to the implicit hierarchy established between all the drawing objects CDD gives the possibility to also define extra links between a given drawing or drawing subject and any other object These relationships allow us to obtain a list of drawings linked in someway to certain equipment or to another object e g ouvrage for the Civil Engineering 41 Links with other objects Links can be defined between drawing subjects or drawings and objects like equipment ouvrages such as buildings or experiment codes If the link is established with a subject all drawings under this subject will inherit this link just as if the link had been explicitly defined for them Links between a particular drawing and any object can also be established If two objects are somehow linked together this information can be used when querying the database For instance if you link a particular drawing with given equipment this drawing will be in the list of drawings retrieved with the appropriate query by equipment This is illustrated in the following example 20 CDD User s manual 1 Add an extra li

31. al 3 Glossary It is important to note that because CDD has been developed in the bilingual environment of CERN where the official languages are French and English some words are given slightly special meanings according to the habits which have developed over many years at CERN In some cases this is because the French word does not have a well known or convenient English equivalent for example ouvrage In others it is because the French meaning of a word is so well known and the word so frequently used by English speaking CERN staff in that sense that it was judged better to use the normal CERN word rather than introduce a new term according to conventional English usage for example the word control is used with an extended meaning borrowed from the French Appro leader Approval process Approvers Archived Control Euclid In work Ouvrage the person responsible for list of approvers the process of collecting comments from list of approvers the members of an approval list used in a general sense to mean entered into CDD It does not have any connotations of no longer active or of no current interest as might be expected from a normal English usage used with an extended meaning borrowed from the French meaning of the word where often check would be the more normal English word The CAD system adopted by CERN and developed by Matra being worked on works building structure o
