Relative vs. Absolute Twist and Dihedral

Introduction

This tutorial will show the difference between using Relative (Rel) and Absolute (Abs) reference flags in setting Twist and Dihedral for a Wing. When using Absolute reference for these angles, the values entered are referenced to the component frame. When using Relative reference, the value is read as a shift or delta in the previous section’s Twist or Dihedral.
