I never used Autocad or Fusion 360, but since the problem is the coordinate system, perhaps you could change the center of the two cut pieces in and place it as if it was the complete piece? Thus, for the cut pieces, the {0,0,0} coordinates would be located on the wall that will stick with the other cut piece. Then CURA should be able to merge them without a hitch.

Autocad, before you slice object , object has gravity center individually, after you slice in two ore more parts, each part has individually gravity centers. when you transferring all parts in cura i can i alight two coordinate to match. But one of (x,y) i don't know to mach in one peace. it could be 0.01 different and it wont be one big peace.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
