You can create a library of standard cables and tubes. The information for standard cables and tubes is stored in an Excel spreadsheet.
The Standard Cables and Tubes PropertyManager appears when you insert a standard cable or tube into an assembly, add items to the library, or delete items from the library.
A sample Excel file is located at <install_dir>\data\design library\routing\standard cables and tubes.xls. You can add your own cables and tubes to the sample file or create a new Excel file based on the sample file format.
