January 18, 2013 202.2 Level Naming Convention ODOT level names use the following naming convention: Classification_Disposition_Logical Name The Classification consists of two (2) uppercase characters used to group the levels into categories. The Classification names are listed in the table below: Classification Description AP Airports BD Buildings BR Bridge CM Corridor Modeler DR Drainage DT Digital Terrain Models DV Divisions EV Environmental GE Geometry GK GEOPAK GM Geomedia (County Maps) GT Geotechnical HY Hydraulics LT Lighting MT Maintenance of Traffic PF Profiles PM Pavement Marking PV Pavement RC Recreational RD Roadway RS Raster Files RW Right-of-Way SC Scratch SG Signals SH Sheets SN Signs ST Standard Construction Drawings & Plan Insert Sheets SV Survey TR Truck Turning Paths TX Text UT Utilities VG Vegetation XS Cross Sections The Disposition is used to identify the level for placement of either X (existing) or P (proposed) information. The Logical Name is used as a description of the element contents. Where appropriate, common industry abbreviations are used. All ODOT levels names use alphanumeric characters only. No spaces or special characters are used other than the underscore “_” character. 6 ODOT CADD Engineering Standards
202.3 ByLevel Considerations January 18, 2013 In general, to facilitate use of MicroStation’s ByLevel attributes, the ODOT levels have been established such that each curvilinear feature will have its own level. In order to keep the overall number of levels manageable, there are cases where similar features will be placed on the same level making it impossible to use ByLevel attributes for those features. Some exceptions are noted below: • Standard ODOT cells are placed on the level in which they were created. Each cell is not placed on its own level, rather, like cells are grouped on one level. For example, existing electric utility cells are all placed on the level UT_X_Electric_Cells. • Storm Sewer Lines – Each proposed storm sewer line 12” and above will be placed using the custom line style stormline, which shall be scaled, based on the pipe size. All proposed storm sewer lines will be placed on the level DR_P_Storm_Sewer. • Culvert Lines – Each proposed culvert line will be placed using a custom line style based on the culvert size. All proposed culvert lines will be placed on the level DR_P_Culvert. • Maintenance of Traffic Drums – Multiple line styles have been created to represent various typical drum spacing’s. These lines are placed on level MT_P_Drums. • Centerline Pavement Marking – Multiple line styles and colors are available representing various centerline pavement markings. These lines are placed on level PM_P_CL (proposed) or PM_X_CL (existing). As a general rule, curvilinear design file elements should be placed using ByLevel attributes except in the cases noted in the CADD Information Table Appendix A. ODOT CADD Engineering Standards 7
