Hi! I guess there is a bit misunderstanding of how Sketch Driven Pattern works. Sketch Driven Pattern command is able to pattern selected features or bodies based on sketch points in a selected 2D or 3D sketch. The features or bodies will be populated to where the points are.
Your image shows you want to pattern features along a sketch path. You will need to use Rectangular Pattern command to do that. If you still cannot figure out, please feel free to post the file here or send it to me directly (johnson.shiue@autodesk.com). We can take a look and suggest the best workflow to use.
Many thanks!
