Created attachment 190791 [details] Comparison of curved connector with Bézier curve The attached file has a connector between the two rectangles. This connector was copied and converted to a Bézier curve. Connector and Bézier curve should produce the same svg:viewBox and svg:d attributes in file markup (besides +- rounding differences). But you get for the connector: svg:d="M7000 7000c0-3001 8000-5501 8000 5000" svg:viewBox="0 0 8001 7609" and for the Bézier curve: svg:viewBox="0 0 8000 7608" svg:d="M0 2608c0-3001 8000-5501 8000 5000" The coordinates (0|2608] in the M command of the Bézier curve are correct, the coordinates (7000|7000) in the M command of the connector curve are wrong. Currently it has no large consequences, because LibreOffice recreates the connector curve from the connection points ins svg:x1, svg:y1, svg:x2 and svg:y2. But it will become a problem, if we start to use the svg:d attribute to decide whether the curve form was created to be compatible with the OOXML definitions or follow the LO way.
Thanks Regina. I can see the different svg:d values in the sample file for connector vs path. In OOo 3.3, the coordinates would differ but the path would have a viewbox whereas the connector wouldn't: Connector: svg:d="m8000 14000c0-2250 9500-750 9500-3000" Path: svg:d="m0 3000c0-2250 9500-750 9500-3000" svg:viewBox="0 0 9500 3000"
