Hi, If you want to import a schematic for worldedit. Follow these steps!
1. Download a FTP client (Filezilla is recommended and used in this tutorial)
2. Go to your server's dashboard and click FTP.
3. Put those details into your FTP client and press quickconnect.
4. Navigate to /plugins/worldedit and create the folder "schematics" if it doesn't already exist and move into it.
5. Drag your schematic into the folder and reload the server (/reload, then /reload confirm).
Hope this helps
