Here is a face with a hole in it, actually a cut:
If you have that part open you can run this:
public static void Test ()
{
PartDocument PartDoc;
try
{
PartDoc = (PartDocument)m_Inventor.ActiveDocument as PartDocument;
if (PartDoc == null)
{
MessageBox.Show("This is not a part document");
return;
}
}
catch
{
MessageBox.Show ("not a part doc");
return;
}
PartComponentDefinition PartDef = PartDoc.ComponentDefinition;
PartFeatures FeatsList = PartDef.Features;
foreach (PartFeature ThisFeature in FeatsList)
{
if (ThisFeature.Type == ObjectTypeEnum.kCutFeatureObject)
{
CutFeature CutFeature = (CutFeature)ThisFeature;
ProfilePath TheProfile = CutFeature.Definition.Profile[1];
ProfileEntity Ent = TheProfile[1];
Debug.WriteLine ("Profile ent " + Ent.ToString() + " " + Ent.CurveType.ToString());
if (Ent.CurveType == Curve2dTypeEnum.kCircleCurve2d)
{
Circle2d Circle = (Circle2d)Ent.Curve;
Debug.WriteLine("It is a circle of radius " + Circle.Radius.ToString());
}
}
else if (ThisFeature.Type == ObjectTypeEnum.kFaceFeatureObject)
{
FaceFeature FaceFeat = (FaceFeature)ThisFeature;
MessageBox.Show("FaceFeature " + FaceFeat.ToString() + " name<" + FaceFeat.Name + "> has " + FaceFeat.Faces.Count.ToString() + " faces");
//Faces FacesList = FaceFeat.Faces;
//FaceFeat.Definition.
//foreach (Face ThisFace in FacesList)
//{
// Face.Edges;
//}
}
else
{
MessageBox.Show("This feature is a " + ThisFeature.Type.ToString());
}
}
}
And you will get this output in the debug window of the IDE:
Profile ent System.__ComObject kCircleCurve2d
It is a circle of radius 0,15.
