I have spent 4 days on one tea spoon: a lot of learning, on line videos and reading posts on this forum; however the last 6 hours have been really futile in that I cannot make this teaspoon solid. I have tried repairing contours, delete and then fill, deleting faces and replacing them and so forth. I think I need fundamentally to fix 'open contours' but cannot work out how to do this.
The Solidworks file is 2014, so I added a universal 3d file of the same model.
Thanks in advance.
