3d Project File Naming Convention

All files distributed by the 3-D Project are 3D CAD model drawings. This is a complete single object drawing that can be inserted, by various methods, into other drawings. The file naming convention used is nine characters in length and divided into three informational fields. This nine-character string is followed by a three-character file extension.

The first field of the file name serves as the discipline code. The discipline code is two characters in length with "-" being used for the second character as a separator. The discipline code represents the profession of the originator of the drawing. For example: A= Architectural, C= Civil, E= Electrical, M= Mechanical, etc. Most drawings distributed by the 3-D Project use "X" as a discipline code. Under the CAD Layer Guidelines there is no designation for Broadcast Engineer. X represents "Other Disciplines".

The second data field of the file name serves to represent drawing type. This field is also two characters in length. All drawings distributed by the 3-D Project are 3D drawings and therefore use "3D" for the drawing type code.

3D Project StandardsThe third, and last, field in the file name is a user definable information field. The 3-D Project has chosen to use this field as a five-character field. The first two characters represent the drawing number of that particular type of object. The last three characters serve as an abbreviated description of the object type. For example "01MIC" designates the first microphone drawing, "02MIC" the second microphone drawing and so on.

In cases where objet type libraries have gone over 99-drawings this third file name field was expanded to a six-character field. The first three characters represent the drawing number (past 99) of that particular type of object. The last three characters serve as an abbreviated description of the object type. For example "101MIC" designates drawing number one-hundred-one of the microphone drawings.

All other drawing file information and details can be found in the Windows file "properties" box. This includes author, creation date, object description, and all other pertinent drawing information.
