I'm hoping this is a basic question.

I have just finished programing a cabinet and checking it over before saving it to the library. While looking it over I found that a part, 'Left Side', is showing in the model, and showing in Part Properties; however, it is missing from the Edit Design Data spreadsheet.

The whole row is missing, it jumps from row 261 to 263. Is there a way to hide and unhide rows in the spreadsheet like can be done in excel?

The model still draws correctly and responds to the prompts, shrinks and grows parametrically etc. The formulas attached to the part are working, turning on and off machine tokens depending upon what prompts are selected in Product Prompts. The only problem is now I do not have access to that part through the Edit Design Data spreadsheet.

Thanks
