I've spotted a couple of posts around Lazy Nezumi and AR6 but so far I've singularly failed to get the two to talk happily (this is W10). At best I get a weird sort of offset from the path and no solid snapping. LZ recommends all smoothing to be switched off, but so far as I know I haven't any smoothing enabled in AR.

LZ could be a bit of a missing link: the guide mode in stencils is OK, but sometimes that precision isn't there. Plus an easier way to complete isometric layouts.
