Top layer missing poligons

ESCAPEKIT — Thu, 19 Mar 2020 17:31:02 GMT

Another fun BUG.
Now the top layer polygons are not showing in the 3D view.
Luckily it is not critical but man, it looks like every half an hour I stumble into a new bug.

Looks like the body for the top layer polygons is missing:

Hello @ESCAPEKIT,

I hope you're doing well. I've pinged the developers on this issue and they'll be looking at this.

Let me know if there's anything else I can do for you.

Best Regards,

Hi @ESCAPEKIT , the Fusion 3D PCB is created as true solids. The edges and faces can be referenced in modeling environment, and even usable in CAM and simulation environment. This requires very strict edge conditions and sometimes the process fails to create a valid 3D body. After all, a valid 2D polygon doesn't mean we can create a valid 3D solid. The routing result will impact the creation of the 3D PCB. So what you can try is to check if there is any routing error first. If no, try to adjust the shape of the polygon.

The last thing you can do is to use the "Create 3D PCB with canvas" command. This should always work even if it's impossible to create a valid 3D polygon.
