I'm very new to Solid Works and just doing tutorials.
I've made a part by sketching 2 circles and extruding those into a ring. Then sketching on that ring and extruding another ring.
But I can't find a way to adjust the sketch before the first extrusion. When smart dimensioning the outer ring from 100 to 200, the size won't change. However, it will display an inaccurate dimension of 200 units.
