To download schematics, you will need to right click on the download link and use the "Save Link As" or "Save Target" button in the context menu that appears. When you do this, you may need to specify a directory to save it to. Once you do, it should be able to be used in mcedit, or in your worldedit schematics. If this does not resolve your issue, please feel free to reply with further issues. Best of Luck!
