有些情况我们需要通过系统的质量属性获取一些信息.

这个api帮助里自带例子.

        private void btn_GetMass_Click(object sender, EventArgs e)
        {
            // 获取质量属性可参考 Get Mass Properties of Visible and Hidden Components Example (C#)

            ISldWorks swApp = Utility.ConnectToSolidWorks();

            ModelDoc2 swModel = swApp.ActiveDoc;

            ModelDocExtension swModelDocExt = (ModelDocExtension)swModel.Extension;

            swModelDocExt.IncludeMassPropertiesOfHiddenBodies = false;
            int massStatus = 0;

            double[] massProperties = (double[])swModelDocExt.GetMassProperties(1, ref massStatus);
            if ((massProperties != null))
            {
                Debug.Print(" CenterOfMassX = " + massProperties[0]);
                Debug.Print(" CenterOfMassY = " + massProperties[1]);
                Debug.Print(" CenterOfMassZ = " + massProperties[2]);
                Debug.Print(" Volume = " + massProperties[3]);
                Debug.Print(" Area = " + massProperties[4]);
                Debug.Print(" Mass = " + massProperties[5]);
                Debug.Print(" MomXX = " + massProperties[6]);
                Debug.Print(" MomYY = " + massProperties[7]);
                Debug.Print(" MomZZ = " + massProperties[8]);
                Debug.Print(" MomXY = " + massProperties[9]);
                Debug.Print(" MomZX = " + massProperties[10]);
                Debug.Print(" MomYZ = " + massProperties[11]);
            }
            Debug.Print("-------------------------------");
        }
