Yeah it's an entirely different skill set. I have 3D printed a lot of parts for my recent project but it's all rectangles and circles, I couldn't get anything much more complicated to come out right. One of the things a mechanical engineer friend of mine suggested is finding a cool SolidWorks file online and learning from it. Basically drag the bar of the feature tree all the way back to the top and you can "play back" the person's design step by step.
