Never used Solidworks, but once you learn how to model, learning other modeling packages is easy. I know how to use 3ds Max (my primary modeling tool), Maya, Zbrush and Blender (Blender is awesome for a free program... heck its awesome even if it wasn't free haha).
Check out tutorialized.com, they have tutorials for everything. Even if the tutorial is for a different package, you can still follow it if you know the tools.
Learn to "box model" first, until you get a sense of working in 3d space, then you can get into more advanced modeling like spline/patch modeling. I box modeled all these lures so far (start with a cube and cut faces and extrude until you get the basic shape, then smooth and subdivide your shape).
I could go on forever so ill stop there
