Does everything in a Seek rfa file have to be pinned down from moving?

[nate0225]

I am working on several Revit Families to submit to Autodesk Seek, and they all flex for differing models.  My problem is that when I pin anything down to prevent movement of the piece within the family it no longer flexes(or at least brings up a error about contraints).  My question is does everything within a family need to be locked down in order to be submitted to Seek? 

Note:  I have everything constrained so if you move it an error message pops up about constraints and as long as the "remove constraints" button isnt selected the pieces move back to where they should be when exiting the error window.
