如何使用solidworks API获取孔的平面？

Question

我想要获取孔所在的平面，我尝试获取穿过特征的面，但它是孔特征内部的面，而不是孔所在的平面。后来我传入特殊孔特征的平面，先调用AccessSelection方法，但还是无法获取孔所在的平面。

                ModelDoc2 swModel = (ModelDoc2)swApp.ActiveDoc;
 if (feature.GetTypeName2() == "HoleWzd")
                    {
                        WizardHoleFeatureData2 wizardHoleFeature = (WizardHoleFeatureData2)feature.GetDefinition();                       
                     
                        if (wizardHoleFeature != null)
                        {
                            // Access selections
                            wizardHoleFeature.AccessSelections(swModel, null);

                            // Get the IWizardHoleFeatureData2 interface
                            // Try to get the face
                            Face2 endConditionFace = (Face2)wizardHoleFeature.Face;

                            if (endConditionFace != null)
                            {
                                // Successfully got the face, proceed with your operations
                                // e.g., getting face properties or geometry
                                Debug.Print("Successfully retrieved the face.");
                            }
                            else
                            {
                                // Face is still null, handle the case
                                Debug.Print("The end condition face is null.");
                            }

                            // Release selections
                            wizardHoleFeature.ReleaseSelectionAccess();


                        }
                        else
                        {
                            Debug.Print("Failed to find the feature.");
                        }

feature.getface 不是我想要的

要获取参考平面，您必须深入挖掘异型孔向导特征创建的草图。

var swSketchPoints = IWizardHoleFeatureData2.GetSketchPoints();
var swSketch = swSketchPoints[0].GetSketch();
var refEntity = swSketch.GetReferenceEntity(out int lEntityType);

if (lEntityType == swSelectType_e.swSelDATUMPLANES)
{
    var swPlane = refEntity as IPlane;
}

获得基本实体后，您可以将其转换为

GetReferenceEntity

返回的类型，如 SW swSelectType_e API 帮助页面上所述
