How to use Extruded Draft

[VPJ19]

Hi.

I'm trying to create cone development.I have use "ExtrudedSurfaces.Add" API but it will not work.I have neglected crown argument.

Thanks.

Profiles Profs = Pdoc.ProfileSets.Add().Profiles;
Profile Prof = Profs.Add(TopPln);  // Plane selection
Relations2d Rels = (Relations2d)Prof.Relations2d;

const double OD = 1.6;
const double height = 0.480;
const double angle = 60 * (Math.PI / 180);
const double thick = 0.006;

Circle2d c1 = Prof.Circles2d.AddByCenterRadius(0, 0, OD / 2.0);
Line2d LV = (Line2d)Prof.ProjectRefPlane(FrontPln);
Rels.AddKeypoint(c1, (int)igCircleCenter, LV, (int)igLineMiddle);

Dimension dimOD = Dim.AddCircularDiameter(c1);
dimOD.Constraint = true;
dimOD.TrackDistance = 0.015;

int stat = Prof.End(ProfileValidationType.igProfileClosed);
Debug.Assert(stat == 0);

//Create a Extruded surface
Profile[] profArr = new Profile[] { Prof };
// ExtrudedSurface mdl = Pdoc.Constructions.ExtrudedSurfaces.AddFinite(1, profArr, FeaturePropertyConstants.igRight, height);

ExtrudedSurface mdl = Pdoc.Constructions.ExtrudedSurfaces.Add(
NumberOfProfiles: 1,
ProfileArray: profArr,
ExtentType1: SolidEdgePart.FeaturePropertyConstants.igFinite,
ExtentSide1: SolidEdgePart.FeaturePropertyConstants.igRight,
FiniteDepth1: height,
TreatmentDraftSide1: SolidEdgePart.DraftSideConstants.seDraftInside,
TreatmentDraftAngle1: angle
);

//Create a Thicken feature

Model mdl2 = Pdoc.Models.AddThickenFeature(FeaturePropertyConstants.igRight, thick, 1, profArr);
Application.Exit();

Vijay,

there are NO optional parameters in the ExtrudedSurfaces.Add() method. You have to define them all!

  PartDocument doc = (PartDocument)app.ActiveDocument;
  RefPlane topPln = doc.RefPlanes.Item(1);
  RefPlane rightPln = doc.RefPlanes.Item(2);
  RefPlane frontPln = doc.RefPlanes.Item(3);

  Profiles profs = doc.ProfileSets.Add().Profiles;
  Profile prof = profs.Add(topPln);  // Plane selection
  Relations2d rels = (Relations2d)prof.Relations2d;
  Dimensions dims = (Dimensions)prof.Dimensions;

  const double OD = 1.6;
  const double height = 0.400;
  const double angle = 60 * (Math.PI / 180);
  const double thick = 0.006;

  Circle2d c1 = prof.Circles2d.AddByCenterRadius(0, 0, OD / 2.0);
  Line2d LV = (Line2d)prof.ProjectRefPlane(frontPln);
  rels.AddKeypoint(c1, (int)igCircleCenter, LV, (int)igLineMiddle);

  Dimension dimOD = dims.AddCircularDiameter(c1);
  dimOD.Constraint = true;
  dimOD.TrackDistance = 0.015;

  int stat = prof.End(ProfileValidationType.igProfileClosed);
  Debug.Assert(stat == 0);
  prof.Visible = false;

  //Create a Extruded surface
  Profile[] profArr = new Profile[] { prof };

  // ALL arguments are REQUIRED!
  ExtrudedSurface surf = doc.Constructions.ExtrudedSurfaces.Add(
    1, profArr,
    // Extension 1
    FeaturePropertyConstants.igFinite, FeaturePropertyConstants.igRight, height,
    null, 0, null, OffsetSideConstants.seOffsetNone, 0,
    TreatmentTypeConstants.seTreatmentDraft, DraftSideConstants.seDraftInside, angle,
    TreatmentCrownTypeConstants.seTreatmentCrownNone, TreatmentCrownSideConstants.seTreatmentCrownSideNone,
    TreatmentCrownCurvatureSideConstants.seTreatmentCrownCurvatureNone, 0, 0,
    // Extension 2
    FeaturePropertyConstants.igNone, FeaturePropertyConstants.igLeft, 0,
    null, 0, null, OffsetSideConstants.seOffsetNone, 0,
    TreatmentTypeConstants.seTreatmentNone, DraftSideConstants.seDraftNone, 0,
    TreatmentCrownTypeConstants.seTreatmentCrownNone, TreatmentCrownSideConstants.seTreatmentCrownSideNone,
    TreatmentCrownCurvatureSideConstants.seTreatmentCrownCurvatureNone, 0, 0,
    false // Don't want caps => keep surface open
  );

  // Get the single cone face
  Faces fcs = (Faces)surf.Faces[FeatureTopologyQueryTypeConstants.igQueryAll];
  Debug.Assert(fcs.Count == 1);

  // Create the face array (of a single face)
  Face[] faceArr = new Face[] { (Face)fcs.Item(1) };

  //Create a Thicken feature
  Model mdl = doc.Models.AddThickenFeature(FeaturePropertyConstants.igRight, thick, 1, faceArr);

Thanks @MartinBernhard 

Passed every argument (almost 32)  is quite lenthy only for  getting draft.

After completion of remaining two commands (Cutout, Flattern) will close this discussion.

Hi @MartinBernhard .While using "FlatPatternModels. Add" it will consist only single argument. After passing them it is shown only feature name.

// Create a Cutout feature
double L = 0.850;
double W = 0.0005;

Profs = Pdoc.ProfileSets.Add().Profiles;
Prof = Profs.Add(TopPln);
Line2d L1 = Prof.Lines2d.AddBy2Points(0, 0, 0, W);
Line2d L2 = Prof.Lines2d.AddBy2Points(0,W,L,W);
Line2d L3 = Prof.Lines2d.AddBy2Points(L,W,L,0);
Line2d L4 = Prof.Lines2d.AddBy2Points(L,0,0,0);

Rels.AddKeypoint(L1,(int)igLineEnd,L2,(int)igLineStart);
Rels.AddKeypoint(L2, (int)igLineEnd, L3, (int)igLineStart);
Rels.AddKeypoint(L3, (int)igLineEnd, L4, (int)igLineStart);
Rels.AddKeypoint(L4, (int)igLineEnd, L1, (int)igLineStart);

stat = Prof.End(ProfileValidationType.igProfileClosed);
Debug.Assert(stat == 0);
Prof.Visible = false;

ExtrudedCutout featCut = mdl.ExtrudedCutouts.AddThroughNext(Prof,FeaturePropertyConstants.igRi, FeaturePropertyConstants.igRight);

// Create Flatten

 FlatPattern fltPattern = (FlatPattern)Pdoc.FlatPatternModels.Add(mdl);

There are two things that you are missing:

• You have only created a FlatPatternModel, not the flat pattern itself. From the FlatPatternModel, create a new FlatPattern.
• SE can only flatten a PART, if it has a material assigned. You may need to do this first BEFORE creating the flat pattern.

BTW: In your code, I don't see the initialization of the Rels variable, which should be specific to a profile, so you will have to get it again from the newly created profile!

Thanks Martin sir.Actually i am looking Flat pattern API in which we can passed Face object like argument.(Seen in SE flat pattern video).Now first i  will search API for material selection and do it again.Releated to Rels variable it has  initialize in above part of code here i just paste remaining code.

After applying material still problem not resolved. I had read the SDK help file which is in VB code and convert into C#. Why below code is not working?

        // Get Material table object handle
                MatTable objMatTable = Appl.GetMaterialTable();

                // Set active document handle
                objMatTable.SetActiveDocument(Pdoc);
                string strMaterial = "Stainless steel";
                string strLibrary = "Materials";
                objMatTable.ApplyMaterialToDoc(Pdoc, strMaterial, strLibrary);
                
                // Create Flatten
                FlatPatternModel flatPatternModel = (FlatPatternModel)Pdoc.FlatPatternModels.Add(mdl);
                Body body = (Body)mdl.Body;
                Faces faces = (Faces)body.Faces[FeatureTopologyQueryTypeConstants.igQueryAll];
                Face face = (Face)faces.Item(1);
                Edges edges = (Edges)face.Edges;
                Edge edge = (Edge)edges.Item(1);
                
                FlatPattern flatPattern = flatPatternModel.FlatPatterns.Add(edge, fcs, edge.EndVertex, FlattenPatternModelTypeConstants.igFlattenPatternModelTypeFlattenAnything);
                

Thanks.

In order to flatten the model, you have to create a Blank:

// ...

// Apply a material to the design model
MatTable matTable = app.GetMaterialTable();
matTable.ApplyMaterial(doc, "Stainless steel");

// Create a FlatPattern model
FlatPatternModel flatMdl = (FlatPatternModel)doc.FlatPatternModels.Add(mdl);

// Find the face with the greatest area (the outer cone)
Body body = (Body)mdl.Body;
fcs = (Faces)body.Faces[FeatureTopologyQueryTypeConstants.igQueryAll];
double maxArea = 0;
Face refFace = null;
foreach(Face fc in fcs)
{
  if (fc.Area > maxArea)
  {
    refFace = fc;
    maxArea = fc.Area;
  }
}

// To flatten the model, create a Blank
flatMdl.Blanks.Add(1, new Face[] { refFace }, 
  0, 0, 1,  // flatten long z-axis
  thick,    // thickness
  0.2,      // strain hardening exponent
  55*10e6,  // 550 MegaPa
  3,        // accuracy: 3 - coarse
  0,        // no offset
  false);
