Traffic editor not showing correct values of x and y for different levels

[jamietjx]

After successfully creating L4, i tried to add a new level(L5). After setting up L5, the value of x and y does not change and remains at nan. Is there a parameter that i have forgotten to set? Below is an image of Lv5.

You'll need to define at least two fiducials on each level that have the same names as the fiducials on the other level(s) that you want to align. If you can send me the traffic map files, I'm happy to debug it in case anything else weird is happening, but anyway, my first reflex is to suggest to create >=2 alignment fiducials on each level first.

oh, I didn't say why, sorry! Two fiducials are needed in order for the alignment algorithm to be able to set the scale, translation, and rotation of the second level precisely against the scale of the reference level (L4, in this case; it's the one highlighted in green).

I've created a bug ticket, because if it can't find enough fiducials, it would be much better to just set the translation to zero, rather than nan.

nan should be fixed now.

Thanks for the help, adding another fiducial solved the problem.
