I find a double-line connector shape [line width = 7 pt] on a diagram loses its Compound type on the Save:
var diagram = new Diagram("DoubleConnector.vsdx");
I can correct the problem manually in Visio by right-click > Styles > Line > Line Options > Compound type drop-down > select ==
Is there a work-around for this? Any way to correct it with the Aspose API?
