Hello,

FlowChart.NET can import only Visio XML Drawing (.vdx) files. Binary Visio files are not supported.

You must add a reference to the VisioImport.dll assembly to your project, create a VisioImporter instance and call its Import method.

VisioImporter imp= new VisioImporter();
imp.ImportEntitiesAsTables = true;
imp.ImportAllPages(vdxPath, fc);
 

I know nothing of "cuppled state charts" and "semantic links with links" Could you post an image that shows what kind of chart you need to get?
