I am developing a C# standalone application to convert an Excel table (component position & orientation) into a SolidWorks assembly.

The data gives:

- Position of component origin with X/Y/Z point

- Orientation of component origin with X/Y/Z vectors

I am using a class to manage sketch entities:

private class InsertPoint
{
    ...
    public SketchPoint Origin;
    public SketchSegment XAxis;
    public SketchSegment YAxis;
    public SketchSegment ZAxis;
    public Feature CoordSystem;
}

I create many points with:

var insertPoints = new List();
insertPoints[i].Origin = skMgr.CreatePoint(...);
insertPoints[i].XAxis = skMgr.CreateLine(...);
insertPoints[i].YAxis = skMgr.CreateLine(...);
insertPoints[i].ZAxis = skMgr.CreateLine(...);

Screenshot of sketch:

But when I try to create the coordinate system:

insertPoints[i].CoordSystem = ftMgr.CreateCoordinateSystem(
    insertPoints[i].Origin,
    new object[] { insertPoints[i].XAxis },
    new object[] { insertPoints[i].YAxis },
    new object[] { insertPoints[i].ZAxis }
);

The coordinate systems has a valid position but not a valid orientation.

The documentation is light and VBA example not clear.

Is somebody can see where is my error ?

Best regards,

Alexandre
