核心逻辑

必须打开机械设备的族模板
创建几何实体来表示风管机
创建风机的接头

创建几何实体来表示风管机

例子中创建了多个拉伸，下面仅截取一段代码：

// 创建一个 curve 数组
curves = app.NewCurveArray();
curves.Append(Line.CreateBound(profileData[i, 0], profileData[i, 1]));
curves.Append(Line.CreateBound(profileData[i, 1], profileData[i, 2]));
curves.Append(Line.CreateBound(profileData[i, 2], profileData[i, 3]));
curves.Append(Line.CreateBound(profileData[i, 3], profileData[i, 0]));

// 创建一个轮廓，curve数组的数组
profile = app.NewCurveArrArray();
profile.Append(curves);

// 创建参考平面
plane = Plane.CreateByNormalAndOrigin(sketchPlaneData[i, 0], sketchPlaneData[i, 1]);
sketchPlane = SketchPlane.Create(m_document, plane);

// 创建一个拉伸
extrusions[i] = f.NewExtrusion(isSolid[i], profile, sketchPlane,extrusionOffsets[i, 1]);
extrusions[i].StartOffset = extrusionOffsets[i, 0];

// 把拉伸加入数组，方便后续的几何合并
m_combineElements.Append(extrusions[i]);

创建风机的接头

例子中有四个接头，两个风管，两个水管。

// 风管接头的例子，创建及设置参数
ConnectorElement connReturnAir = ConnectorElement.CreateDuctConnector(m_document, DuctSystemType.ReturnAir, ConnectorProfileType.Rectangular, m_planarFaces[0].Reference);
param = connReturnAir.get_Parameter(BuiltInParameter.CONNECTOR_HEIGHT);
param.Set(connectorDimensions[1, 0]);
param = connReturnAir.get_Parameter(BuiltInParameter.CONNECTOR_WIDTH);
param.Set(connectorDimensions[1, 1]);
param = connReturnAir.get_Parameter(BuiltInParameter.RBS_DUCT_FLOW_DIRECTION_PARAM);
param.Set(1);
param = connReturnAir.get_Parameter(BuiltInParameter.RBS_DUCT_FLOW_CONFIGURATION_PARAM);
param.Set(1);
param = connReturnAir.get_Parameter(BuiltInParameter.RBS_DUCT_FLOW_PARAM);
param.Set(flow);
// 水管接头的例子，创建及设置参数
ConnectorElement connSupplyHydronic = ConnectorElement.CreatePipeConnector(m_document, PipeSystemType.SupplyHydronic, m_planarFaces[0].Reference);
param = connSupplyHydronic.get_Parameter(BuiltInParameter.CONNECTOR_RADIUS);
param.Set(arcRadius);
param = connSupplyHydronic.get_Parameter(BuiltInParameter.RBS_PIPE_FLOW_DIRECTION_PARAM);
param.Set(2);
