Problem cant get rid of solidcam from a part created internally within the solidworks part

I decided to try creating a new milling operation using the option "internal within solidworks part". Now when ever I open up the part without Solidcam I get the message choose part. I can not disassociate the part from solidcam and also cannot create a new milling operation with this part as always tells me illegal plate when choosing the coordinate system.

Is there a way to remove all reference from a solidworks part so that I can start over??:drowning:

I did look all day for a solution, even tried to open the part with a good text editor to see if it might store it in the header...but no luck.
