Example: {{{ *data normal from to tape compass clino 1 2 3.75 209.4 -14.1 3 2 6.57 18.3 -3.3 3 4 3.45 292.4 6.5 3 5 2.97 225.6 10.5 5 6 1.79 111.9 3.4 }}} In Inkscape, the angles are: {{{ 1-2 ... 209.45° 3-2 ... 18.21° 3-4 ... 292.45° 3-5 ... 225.69° 5-6 ... 111.98° }}} The error in 3-5 is noticeable. I've been noticing these differences for many years and blamed them on some maximum resolution or snapping in Inkscape. But the lines can actually be manually drawn with the correct length and angle in Inkscape. So there must be a serious inaccuracy somewhere in the transformation process." defect new minor cavern 1.2.17
