Change a contour defining a feature

Hi all,


We are having trouble replacing the defining contour of an extruded feature body.

We have generated a new set of SketchSegments, found the SketchContour containing these segments and

are attempting to replace a previously specified contour with the new contour we have created.

  • Is it possible to change the contour of an extruded feature, a "BossThin" feature in this case?
    • If so what are the prerequisites for a contour to be applied to an extruded feature, a "BossThin" feature in this case?
    • Can a PropertyManagment page be open while making the change?
    • Can a sketch be active while making the change



Here is a snippet of what we think should achieve our goal but is not working.

No sketch is active.

This is in the OnClose of a PropertyManagmentPage.


Where selectedFeature is the feature to modify

Where foundContour is the contour we would like to define the ExtrudeFeature


ExtrudeFeatureData2 fd = selectedFeature.GetDefinition() as ExtrudeFeatureData2;
fd.AccessSelections(targetDocument, null);
int contourCount = fd.GetContoursCount();
object[] sketchContours = fd.Contours;
if (null == fd.Contours) {
fd.Contours = new object[1];
fd.Contours[0] = foundContour;
bool result = selectedFeature.ModifyDefinition(fd, targetDocument, null);


Any suggestions would be greatly appreciated
