What I can’t figure out is how the first component (the top layer of the dash with the fine details) could be on one plane, and the second component (lens layer) could be on a different plane. I created the second component “on top” of the first component. As I was creating the Lens Layer sketch, I was using the reference points on the Dash sketch to create the circles and the steering column cut-out. But still, when I save the Dash component flat pattern as a dxf, the orientation is perfect. When I save the Lens layer as a dxf, it’s inverted. At this point it’s more about my understanding how it happened so I can avoid the same mistake in the future.
That’s a weird issue. It sounds like the Lens Layer might have been projected onto a different orientation or plane when it was created. In Fusion 360, even slight differences in how the sketch references are aligned can mess with the DXF export. Have you checked the plane and orientation settings for the Lens Layer sketch compared to the Dash layer? That might be the key to avoiding it in the future.
If you are looking at one of my f3d files, I very well did that. I changed (redefined the sketch plane) one time and then activated the component for the dash plate and the flat panel was fixed. But, invariably I changed one sketch but none of the others. So…my fault.
It is possible that you ended up with the reverse image, in the first place, was that you might have been working from the FRONT side on one sketch and then worked on another component from the BACK side.
