Learn how to effectively use Autostrut and Rigid Attachment in Kerbal Space Program to build stable and robust spacecraft. This guide covers their functions and best practices for successful launches.

Walkthrough
  1. 1
    Autostrut: This feature allows you to create flexible connections between parts. When enabled, Autostrut will automatically adjust its connection point to the most structurally sound location on the target part, helping to prevent wobbling and breakages during flight. You can set Autostruts to connect to the root part, the nearest part, the furthest part, or a specific part.
  2. 2
    Rigid Attachment: This is a more permanent solution. When you enable Rigid Attachment on a connection, it creates an unbreakable link between the two parts. This is particularly useful for critical structural points or for parts that you absolutely do not want to move independently of each other.
Tips
  • Use Autostrut liberally on long or complex craft, especially on the main structural components, to prevent them from flexing and breaking apart.
  • Experiment with different Autostrut modes (Root, Nearest, Furthest) to see which provides the best stability for your specific design.
  • Rigid Attachment is best used for components that must remain perfectly aligned, such as docking ports or the core structure of a large vessel.
  • Be mindful that Rigid Attachment can sometimes make it harder to decouple parts if not planned carefully.
  • For very large or complex structures, consider using a combination of Autostruts for general stability and Rigid Attachments for key connection points.
