Constructed Width Error

I am measuring two planes PLN3 and PLN4, both in Z+. I would like to create a constructed width. I create a reverse plane from my top plane so it has normal Z-. Below it I have a plane with normal Z+. Constructed Width - 3D - In tells me "Math failed. Make sure that the areas of the inputs overlap." Any ideas?

  • I went ahead and made two auto planes. Nominals are the same up to the difference in height (Z). Flipped one by using constructed reverse plane. Same error when trying to construct a width.

    It is an issue with reverse plane used for the width. When I flip the actual vectors of one of the planes (as if I could actually measure the part this way) the width constructs fine. Just not when I involve reverse plane...
