It is important to understand how CSD Siteworks manages your surface data, volumes, and outputs.
When you create a surface or run a CSD Siteworks command, the software creates a data folder and associates it to the source drawing based on the folder location and name.
If you decide to rename or relocate your drawing, you need to also consider renaming and/or relocating the associated -Data folder in order to continue accessing the surface and other data you've created.
If you find that your data is 'lost', it is likely that you changed the drawing name/location and forgot to do the same for the associated -Data folder.
The video below provides and overview of how data is managed, both for the current drawing and when new drawings are created.
Note: The ribbon displayed is for Civil Site Design. For CSD Siteworks, you can open the CSD Settings folder from Siteworks > Settings > Open Settings Folder. The command to network the CSD Settings folder is not available in CSD Siteworks.
