Use the following naming conventions:
General File Naming
The WFLHD file naming convention consists of a project specific prefix followed by a short file type suffix.
<unique project prefix> + <file type> + .extension
Note: Do not change the default file extension (i.e. DGN, DOCX, XLSX, PDF, etc.
See the listing of unique project prefixes.
Design Files Types
Most plan sheets reference other roadway design files containing the planimetrics (existing ground features), contours, and new work. Use the suffixes shown below to describe these roadway design files. If applicable sequential numbers may be added (e.g. *_ali1.dgn, *qty2.dgn, *xs01, *xs02.dgn, etc.).
| Data Type | Suffix | Seed File | Purpose |
|---|---|---|---|
| Survey | _sur | 3D | Existing 3D Survey Data including terrain |
| Right of Way | _e_row _p_row | 2D | Existing Right of Way (E_ROW) Proposed Right of Way (P_ROW) |
| Alignment and Profile | _ali | 2D | Horizontal and vertical alignments |
| Corridor | _cor | 2D | Design corridor files |
| Superelevation | _sup | 2D | Superelevation creation |
| Cross Sections | _xs | 2D | Creation of cross section named borders, XS sheets, and printing |
| Quantities | _qty | 2D | Quantity named boundaries, earthwork, etc. |
| Civil Cells | _cvc | 2D | Civil cell placement and processing. Use separate files when many civil cells are modeled |
| Plan Sheets | _pln | 2D | Creation of named border, plan sheets, and printing. Additional plan sheet descriptor may be added. |
Additional suffixes may be added for design files created by other functions.
<unique project prefix> + <function code> + <file type> + .dgn
