Profile cross-sections use 2D symbol files that have parameters and are defined in the catalog.
Profile cross-section symbols are delivered to [Reference Data Folder]\SharedContent\Profile Xsections. The symbols are also bulkloaded into the catalog. For more information, see Profile Cross-Sections Workbook.
You can modify the geometry and parameters of the symbols. For more information, see Creating Profile Cross Sections in the 2D Symbol User's Guide.
