MVD MODEL FILE NAMING 

7 February 2010

Electronic Drawing File Naming Convention 

Electronic files shall be named as recommended in Chapter 2 of the A/E/C 

CADD Standard. This naming convention allows for the use of 28 

characters, with the first 20 characters being optional. The first 

twenty optional characters, defined as the Project Code in the A/E/C 

CADD Standard, shall be as defined below. The actual number of 

characters utilized in the Project Code field may vary (20 character 

maximum). However, use of the last eight characters of the file name, 

those immediately preceding the file extension, is mandatory. 

Model Files 

The first 20 characters (Project Code) of a model file name shall 

consist of a ProjectWise (PW) Project code/name and model file 

description (optional). The PW Project code/name shall be the same for 

each project drawing file. The PW Project Code/Name is assigned by the 

ProjectWise Administrator. Use of the underbar symbol “_” to separate 

the fields is optional. 

 

EXAMPLE: A model file containing the site plan for Mississippi River would have the model file 

name MR76_SitePlan_C-SP0001.dgn.

The following are examples of Model File Descriptions. The underbars 

shown in the example above are optional, but must be included in the
