Can I open a Unigraphics part in Solidworks and keep the original sketch dimensions and relationships

I am trying to open a Unigraphics part in Solid works and keep the dimensions and sketch relationships that originally defined the part.

I can open it and see and edit the sketch but they are all undefined.

The purpose of the model was to give us the existing tolerancing information as they build from the part not a drawing.
