Hi Xaveer,

Thanks for getting back to me about this. I ran some tests. I can see for instance that with 1-nm accuracy a 20 micron radius curve has vertices about every 1 degree. At this spacing, if the vertices were placed perfectly, the maximum deviation midway between two vertices from a perfect curve is <1nm. I’m still a little concerned about errors adding up over a long phase arm since the vertices themselves are snapped to a grid. For this reason I’ll probably keep using increased accuracy specifically for phase-sensitive components.

In my testing it appears I can connect two cross-sections that use different-accuracy layers in Nazca which map to the same GDS layers. So, this should be a suitable solution for my concern.
