C# Inventor二次开发—002—启动Inventor及零部件创建和打开

一、启动Inventor

　　Inventor.Application对象是基于COM开发Inventor的出发点，以下是我封装获取Inventor Application方法：

        /// <summary>
        /// 获取InventorApplication对象
        /// </summary>
        /// <returns>InventorApplication对象</returns>
        public static Application GetInventorApp()
        {
            Inventor.Application inventorApp = null;
            try
            {
                inventorApp = Marshal.GetActiveObject("Inventor.Application") as Inventor.Application;
            }
            catch
            {
                var inventorType = Type.GetTypeFromProgID("Inventor.Application");
                inventorApp = Activator.CreateInstance(inventorType) as Inventor.Application;
                inventorApp.Visible = true;
            }
            return inventorApp;
        }       

二、创建和打开零件文档

（1）创建零件文档

               PartDocument partDoc = inventorApp.Documents.Add(
                DocumentTypeEnum.kPartDocumentObject,
                inventorApp.FileManager.GetTemplateFile(DocumentTypeEnum.kPartDocumentObject, SystemOfMeasureEnum.kDefaultSystemOfMeasure, DraftingStandardEnum.kDefault_DraftingStandard, null),
                true) as PartDocument; 

（2）打开零件文档

PartDocument partDoc = (PartDocument)inventorApp.Documents.Open(fileName,true);

三、创建和打开部件文档

（1）创建部件文档

              AssemblyDocument asmDoc = inventorApp.Documents.Add(
                DocumentTypeEnum.kAssemblyDocumentObject,
                inventorApp.FileManager.GetTemplateFile(DocumentTypeEnum.kAssemblyDocumentObject, SystemOfMeasureEnum.kDefaultSystemOfMeasure, DraftingStandardEnum.kDefault_DraftingStandard, null),
                true) as AssemblyDocument;

（2）打开部件件文档

AssemblyDocument asmDoc = (AssemblyDocument )inventorApp.Documents.Open(fileName,true);
