Solidworks help (sub-assembly resize?)

I hate to sound like an idiot, but I designed an entire assembly twice as big as I needed to. The radial dimensions I used on the first part, and every part thereafter, were supposed to be diameter dimensions. Is there any way of resizing the entire assembly or sub-assemblies without having to go back and redesign every part individually?

Thanks in advance for any help you may have.

You could change each individual radius. Or you can scale each components and update the mates

(From the Help Menu)

In a part document, click Scale on the Features toolbar or click Insert, Features, Scale.

The Scale PropertyManager appears.

From the Scale about list, select: Centroid, Coordinate System, or Origin.

For uniform scaling, specify a scaling value in the Scale factor box.
