File-Naming Convention
CADD Microstation File-Naming Convention
The following is an example of the file-naming convention that shall be used when developing bridge project plan sheets:
- s2020ad2.dgn
| First Entry | Second Entry | Third Entry | Fourth Entry |
|---|---|---|---|
| s | 2020 | ad2 | .dgn |
| Structure | Structure number without leading zeroes | Abbreviated sheet type plus sheet sequence number (See note and table below) |
File extension |
Note: The third entry should be the abbreviated sheet type and sheet sequence number as follows:
- Do not include a sequence number for a single sheet type.
For example, if there is a single abutment detail sheet: s2020ad.dgn - If there are more then one sheet of a particular type, the sequencing shall start with 1.
For example, if there are two abutment detail sheets: s2020ad1.dgn and s2020ad2.dgn
