Look at this sheet metal:
Although it could be shown as a single face it is in fact 2 faces. It probably depends on how t was constructed. Anyway this code will list the two profiles (if they are made of LineSegment2d:
public static void Test2 ()
{
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(" ...is a circle of radius " + Circle.Radius.ToString());
}
}
else if (ThisFeature.Type == ObjectTypeEnum.kFaceFeatureObject)
{
FaceFeature FaceFeat = (FaceFeature)ThisFeature;
Debug.WriteLine("FaceFeature <" + FaceFeat.Name + "> has " + FaceFeat.Faces.Count.ToString() + " faces");
Debug.WriteLine(" the profile has " + FaceFeat.Definition.Profile.Count.ToString() + " objects");
foreach (ProfilePath ThisPath in FaceFeat.Definition.Profile)
{
Debug.WriteLine(" this path the profile has " + ThisPath.Count.ToString() + " entities");
foreach (ProfileEntity ThisEnt in ThisPath)
{
if (ThisEnt.CurveType == Curve2dTypeEnum.kLineSegmentCurve2d)
{
LineSegment2d Line2d = (LineSegment2d)ThisEnt.Curve;
string sX0 = string.Format("{0,8:0.00}", Line2d.StartPoint.X);
string sY0 = string.Format("{0,8:0.00}", Line2d.StartPoint.Y);
string sX1 = string.Format("{0,8:0.00}", Line2d.EndPoint.X);
string sY1 = string.Format("{0,8:0.00}", Line2d.EndPoint.Y);
Debug.WriteLine(" LinSeg, X:" + sX0 + " Y:" + sY0 + " --> X:" + sX1 + " Y:" + sY1);
}
}
}
// Un false this to see even more detail
#if false
Faces FacesList = FaceFeat.Faces;
// Face BiggestFace = null;
foreach (Face ThisFace in FacesList)
{
Debug.WriteLine(" this face has vertices: " + ThisFace.Vertices.Count.ToString() + " (feature: " + FaceFeat.Name + ")");
foreach (Vertex v in ThisFace.Vertices)
{
Point p = v.Point;
Debug.WriteLine(" " + p.X.ToString() + " " + p.Y.ToString() + " " + p.Z.ToString());
}
}
#endif
}
else
{
Debug.WriteLine("This feature is a " + ThisFeature.Type.ToString());
}
}
}
And the output will look like this:
FaceFeature <Face1> has 3 faces
the profile has 1 objects
this path the profile has 4 entities
LinSeg, X: 0,00 Y: 0,00 --> X: -53,30 Y: 0,00
LinSeg, X: -53,30 Y: 0,00 --> X: -53,30 Y: -53,00
LinSeg, X: -53,30 Y: -53,00 --> X: 0,00 Y: -53,00
LinSeg, X: 0,00 Y: -53,00 --> X: 0,00 Y: 0,00
FaceFeature <Face3> has 1 faces
the profile has 1 objects
this path the profile has 4 entities
LinSeg, X: 8,05 Y: 0,00 --> X: 8,05 Y: -3,50
LinSeg, X: 8,05 Y: -3,50 --> X: 52,90 Y: -1,90
LinSeg, X: 52,90 Y: -1,90 --> X: 52,90 Y: 0,00
LinSeg, X: 52,90 Y: 0,00 --> X: 8,05 Y: 0,00
...and shows that there are two FaceFeatures.
