<br>Hey,<br><br>The NEN1878 provides info as a CircularArc. I'm capabale of creating a<br>FdoICircularArcSegment, but have difficulties returning the IGeometry*<br>for<br>it (or the FdoByteArray*).<br><br>Question: How do I convert a FdoICircularArcSegment into a FdoIGeometry*
<br>or<br>FdoByteArray*? (for usage in the readers GetGeometry function)<br><br>Note: Turning the FdoICircularArcSegment into Geometry via Envelope<br>doesn't<br>seem to work; or returning the 3 points as part of a CurveString. (But I
<br>might be overlooking something)<br><br>Thanks in advance<br>Piet<br>--<br>View this message in context:<br><a href="http://www.nabble.com/Using-CircularArc-in-NEN1878-provider-tf4547783s18">http://www.nabble.com/Using-CircularArc-in-NEN1878-provider-tf4547783s18
