Component: default → OGR_SF
Milestone: → 1.9.2
Resolution: → fixed
Status: new → closed

This is due to an extrusion vector of (0,0,-1) (line 1671 to 1676 of arc.dxf), instead of the default (0,0,1). So an OCS to WCS transformation is needed for ARC too. See #3372

trunk (r25030) and branches/1.9 (r25031) : "DXF: take into account extruction vector to transform from OCS to WCS for MTEXT, TEXT, POINT, LINE, CIRCLE, ELLIPSE, ARC, SPLINE and HATCH (#4842)"
