I have a .obj file that I have created. What I would like to do is manipulate this in Solidworks 2018. I can only seem to import this as a graphic type - by choosing Preferences > Import.

If I ask Solidworks to import the .obj file as a solid I seem to get nothing in the import process. Just an item in the tree but no actual model of any kind.

I have attached the file in question and I wonder if anyone can help me to either convert this to a Solidworks part - as a solid - or advise where I am going wrong.

Many thanks, Daniel.
