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?

  • Construct Width won't work on anything that doesn't contain points such as construct reverse plane. You can try to do a workaround by constructing generic points and plugging in the xyzijk of your leveling plane but add in a *-1 on the vector to flip it then construct plane using those generic points. This will allow the construct width feature to work.

    DISCLAIMER: I actually haven't done any live testing of the above method. Haven't had the need. Only tried it in an offline theoretical situation. So triple check your results!

    The Idea from Sora5 is interesting indeed. Creating generic points and tying them to the actuals of the measured points and mathing the vectors. Have any of you ever tried this ? Will a width work with planes constructed from generic points like this ? do those count as "measured" points ?

    How would one efficiently do this with scan data ? I can think of a way with reference variables and a loop, but that seems tedious. Can anyone think of more elegant method of accomplishing this task ?
