Reading a Diagram with Multiple Radii

Hi SketchUp forum! I am trying to read a diagram of a railroad profile and model its 2D equivalent in SketchUp. I rudimentarily understand how to bevel/radius a single 90deg corner, but my diagram requires a curve with multiple radii and beveling corners that aren’t exactly 90deg. Here’s the diagram I’m working with: [image] What are the techniques or ways used to go about doing that, and if you have any helpful tips for a total n00b, let me know! Thanks!
