The A-Pillar Obstruction wizard measures this obscuration using the methods recommended by these standards, and reports whether the vehicle adheres to the standard or violates it. You can also work in reverse, and create criteria geometry (such as sight lines) for an A-pillar, given a target obstruction angle.

      <p class="para_topic">Use A-Pillar Obstruction during visibility studies to determine the right obstruction angle that conforms to the guidelines of SAE and EEC. You can generate sight lines given a target obstruction angle and outboard or inboard point of the A-pillar. </p>
