As far as I can see there are still some issues with the source models. They don't quite jigsaw together and align correctly and the bottom as you can see in the image.
I've played with the geometry a little to get it to work, but it might need a tidy up! Aside from I've made a couple of other changes as follows:
- Move the pivots for the frame to the Inside on the X and Y axis and updated pivot settings. Now Top/Bottom uses Y pivot, Start/End uses Z Pivot, and Corners use X and Y Pivot. All segments use Z pivot. This will save on having to resize one generator to fit inside/outside another.
- Sliced the wire segments slightly differently to make them easier to line up on the X axis.
- Changed/removed several padding and translation settings.
- Shared same X/Y spline between both generators
I hope it helps, please let me know if you have any questions.
