Imported Curves from AutoCAD

Dear All,

Apologies if this is rudimentary, but I'm fairly new to Solidworks.

I have a drawing from AutoCAD that has been imported in to solidworks. However, once imported, the sketch cannot be edited and just lists a number of "imported curves". Could someone please help advise me how to make this editable?!

Many thanks,

Matti
