After installing Civil Site Design on BricsCAD, occasionally the CSD menu / ribbon is not loaded.
To load the CSD menu into BricsCAD:
run the MENULOAD command
click on the [...] and browse to C:\ProgramData\CSS\ARD\Menu
Select the menu for your version of CSD, i.e. if using CSD V26, the file will be named CSDBricsV26.cui
upon returning to the main panel, click on Load
Your CSD ribbons, menus, etc will now be loaded and displayed
