Constructed Width Error

JacobCheverie
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?

  • As already has been said, a WIDTH can only be constructed from opposing planes, containing hits. The idea from Sora5 is interesting, and might work, but you risk getting the position of the width wrong if you use BFRE in the construction. Also, I have noted problems now and the when mixing 'real hits' and 'constructed hits' in the same construction command.
