I have a part with configurations. I made a design table but decided i didn't need it so I deleted it. So now i want the use the configure feature option for changing dimensions in a sketch but now it grayed out the columns and i can't edit the values anymore (unconfigure mode) How can i put the columns back in configure mode? I can still edit the values by going to the configuration I want and edit the sketch and change the value. But I want to change all the values in the configure feature window.
