Interface,，,应用程序接口），可以使用,VB/VB/VC/Delphi,等高级语言对,SolidWorks,进行二次开发，建立符合要求的、专用的,SolidWorks,功能模块,VBA（Visual Basic for Applications）,VBA,（,Visual Basic for Applications,）,是,1993,年由,Microsoft,推出的一种可以被多种应用程序共享的、针对应用程序内部可编程的、通用的可视化应用程序编程语言。,VBA,是一套完整的应用程序开发环境，它为用户和开发人员提供了一种应用程序间通用的应用程序语言，减少了学习时间和支持费用。,在,Microsoft Office,中，所有的应用程序都可以使用,VBA,在,SolidWorks,中，,VBA,最常见的用途即是录制宏。几乎所有用键盘或菜单命令完成的动作均被宏记录下来，然后对不同的数据进行（或播放）同一批操作。,用,VB,开发,Solidworks,的一般步骤,SolidWorks,的对象、方法很多，其中,SldWorks,对象有,98,种方法，,ModelDoc,对象有,477,种方法，通常，开发者先录制一段宏，然后将宏代码修改后复制到,VB,中去。,用,VB,开发,Solidworks,的一般步骤,宏是一系列命令的集合，相当于,Dos,的批处理文件，可以通过录制使用,SolidWorks,用户界面执行的操作，然后使用,SolidWorks,宏重新执行这些操作。,用,VB,开发,Solidworks,的一般步骤,打开宏录制,1.,在,Solidworks,中，应用纪录宏（,【,工具,】,【,宏操作,】,【,录制,】,停止宏,保存于文件夹,2.,操作、停止并保存,3.,编辑宏,VBA,套零件的代码,4.,执行宏操作,用,VB,开发,Solidworks,的一般步骤,将宏录制的代码照搬到,VB,，并不一定能够绘图，有时会出现错误，需进行修改。,SolidWorks,二次开发常用代码,打开,SolidWorks,新文件,SldWorks:NewPart,：,打开一个被自动命名的新零件,SldWorks:NewDocment,(,模板名，图纸尺寸，用户纸宽，用户纸高,),：,创建一个具有模板名的新文件,SldWorks:NewAssembly,：,创建一个被自动命名的装配体文件,SldWorks:NewDrawing2,（,模板类型，模板名，图纸尺寸，纸宽，纸高,）：,创建一个新的具有模板或用户图纸的工程图文件，文件名被自动命名。,保存和退出文件,ModelDoc:SaveAs,(,文件名，版本信息，选项，,.),：,用不同的名称保存文件,ModelDoc:SaveAs2(,文件名,),：,用新名字保存文件,SldWorks:ExitApp,退出,SolidWorks,保存在当前路径：,App.path&“,文件名”,其他代码,ModelDoc2:InsertSketch2:,开始,/,结束草图绘制,ModelDoc2:ClearSelection(),：,清除任何选择,ModelDoc2.InsertKetchText(X,坐标，,Y,坐标，,Z,坐标，文本，文本的对齐方式,):,插入草图文本,Part.FeatureExtrusion,(,拉伸方向，终止,1,，终止,2,，拉深深度,.),例：,Part.FeatureExtrusion,1,0,1,0,0,0.02,0.02,0,0,0,0,0.017,0.017,0,0,其他代码,Mddeldoc:Featurecut4(,单（双）向，反侧切除，方向,1,，终止,1,，终止,2,，切割深度,1,，切割深度,2,，拔模,):,VB,连接,Solidworks,Dim,swApp,As
