UG NX二次开发(C#)-装配-添加组件

Posted 2021-11-23 GimiGimmy

在UG NX的使用过程中，装配是很重要的一环，本文是为了实现组件的批量装配，采用UG NX二次开发，采用的主要函数为AddComponent。

AddComponent()的帮助说明如下：

其是属于NXOpen.Assemblies空间的ComponentAssembly类，

采用：

using NXOpen.Assemblies;

其实现代码如下:

 /// <summary>
        /// 添加组件
        /// </summary>
        /// <param name="sourcePart">需要添加的组件全路径</param>
        /// <param name="destinationPart">组件名称</param>
        /// <param name="referenceSetName"></param>
        /// <param name="component"></param>
        public static void AddComponent(string sourcePart,string destinationPart,string referenceSetName,out Component component)
        {
        
            Point3d basePoint = new Point3d(0,0,0);                                                    
            double[] mtx = new double[9] { 1.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 1.0 };
            UFMtx3 uFMtx3 = theUFSession.Mtx3;
            double[] vecProduct = new double[3];
            double[] pipeLineVector = new double[3] { 0, 0, 1 };

            uFMtx3.VecMultiply(pipeLineVector, mtx, vecProduct);
            double[] pipeLineMtx = new double[9];
            uFMtx3.InitializeZ(vecProduct, pipeLineMtx);

            NXOpen.Matrix3x3 orientation = new NXOpen.Matrix3x3();
            orientation.Xx = pipeLineMtx[0];
            orientation.Xy = pipeLineMtx[1];
            orientation.Xz = pipeLineMtx[2];
            orientation.Yx = pipeLineMtx[3];
            orientation.Yy = pipeLineMtx[4];
            orientation.Yz = pipeLineMtx[5];
            orientation.Zx = pipeLineMtx[6];
            orientation.Zy = pipeLineMtx[7];
            orientation.Zz = pipeLineMtx[8];

            int layer = workPart.Layers.WorkLayer;            
            PartLoadStatus partLoadStatus;
            component = workPart.ComponentAssembly.AddComponent(sourcePart, referenceSetName, destinationPart, basePoint, orientation, layer, out partLoadStatus, true);
            partLoadStatus.Dispose();
        }

在代码中，需要注意的是这个组件是添加在workPart下面的，workPart是显示部件，即是：

 PartLoadStatus partLoadStatus;
 theSession.Parts.SetDisplay((BasePart)workPart,true,true,out partLoadStatus);

效果如下图所示：
