与三维几何体相关的参数模型的生成方法和设备Method and device for generating parametric models related to three-dimensional geometry

技术领域technical field

本发明涉及与一个或一套部件的三维几何体相关联的参数模型的生成。The invention relates to the generation of a parametric model associated with the three-dimensional geometry of a component or set of components.

它实现了在几何体建模(计算机辅助设计CAD)，机床数控程序(计算机辅助制造CAM)，计算机辅助工程程序以及数据管理软件中的应用。It realizes the application in geometry modeling (computer aided design CAD), machine tool numerical control program (computer aided manufacturing CAM), computer aided engineering program and data management software.

背景技术Background technique

通常方式下，三维几何体参数模型的生成在于直接确定一个部件的最终构型，例如安装在飞机机身上的机翼。Typically, the generation of parametric models of 3D geometry consists in directly determining the final configuration of a component, such as a wing mounted on an aircraft fuselage.

实际上，这样一种最终确定融入一种优化循环中，在此优化循环过程中要经过几次三个重要步骤：确定，分析和修改。In fact, such a finalization is integrated into an optimization cycle during which three important steps are passed several times: determination, analysis and modification.

一款CAD软件的最本质优点是能够使这三个重要步骤部分或全部融入至唯一且独一无二的工作环境里，从一个步骤到下一个步骤的过渡通过几乎透明的方式实现。The most essential advantage of a CAD software is the ability to integrate some or all of these three important steps into a single and unique working environment, where the transition from one step to the next is achieved in an almost transparent manner.

参照图1，显示了一款类似法国达索系统公司开发，IBM公司销售的名为CATIA的CAD软件的工作环境。如显示在计算机显示屏上的工作环境主要包括一个规格树2和图形区4。Referring to Fig. 1, it shows a working environment similar to the CAD software named CATIA developed by Dassault Systèmes of France and sold by IBM. The working environment as displayed on the computer screen mainly includes aspecification tree 2 and agraphic area 4 .

工作环境包括一个菜单栏6，一个标准工具栏8，一个对话区10，一个包含附属在现用(活动)(actif)工作区的背景工具栏12的工作台，一个可以为当前视角指向的指南针14，一个现用工作区的图标16，和一个说明工具栏或应用工具栏18。The work environment includes amenu bar 6, astandard toolbar 8, adialog area 10, a workbench containing a background toolbar 12 attached to the active (active) (actif) work area, a compass that can be pointed for thecurrent viewing angle 14, anicon 16 for the active workspace, and a description toolbar orapplication toolbar 18.

规格树2是一种当前正在实现的一个模型的结构图形表示，这里是一架飞机。在图1的例子中，可以观察到正在进行被命名为产品1的现用元素，该产品包含5个独立的主体20A“环境”，20B“飞机机身1”，20C“机翼”，20D“对称翼”和20E“尾部”，一个主体由应用程序40和命令参数30构成。Specification Tree 2 is a graphical representation of the structure of a model currently being implemented, in this case an aircraft. In the example of Figure 1, it can be observed that an active element named Product 1 is in progress, which consists of 5separate bodies 20A "Environment", 20B "Airplane Fuselage 1", 20C "Wing", 20D "Symmetrical Wing" and 20E "Tail", a body consists ofapplication 40 andcommand parameters 30.

随着部件的确定，模型树的新项目更为丰富。With the identification of parts, the new items of the model tree are enriched.

一个元素的选择在图表区4或者规格树2内完成没有区别。规格树允许激活被选定对象的背景菜单。It makes no difference whether the selection of an element is done in thediagram area 4 or thespecification tree 2. The specification tree allows to activate the context menu of the selected object.

规格树2每一个元素可以包括命令参数30以及关系(未显示)，它们能够通过定义规格树中当前功能影响一个或多个实体的几何图。Each element of thespecification tree 2 may includecommand parameters 30 and relationships (not shown) capable of affecting the geometry of one or more entities by defining the current functionality in the specification tree.

这样一个CAD软件的使用同样能够实现一个数字模型并以相应的方式确定产品和某些与之相关的工艺流程。The use of such a CAD software likewise makes it possible to implement a digital model and define the product and certain processes associated therewith in a corresponding manner.

最常见的是，三维几何模型的确定是数个工作组的努力，通常在不同的地点组织这些工作组，经常是跨国界的。由此产生对参数信息简单容易的交流的强烈需求。Most commonly, the determination of the 3D geometric model is the effort of several working groups, usually organized in different locations, often across borders. This creates a strong need for simple and easy communication of parameter information.

在实际中，定义参数直接由软件工具的本来的功能性决定，尤其是“CATIA”。要修改一个模型的参数值，无需重新编译应用程序。只需使用软件的标准功能来修改参数。尽管如此，软件工具以与构建历史有关的结构组织或以隶属树形式表示模型。In practice, the definition parameters are directly determined by the intrinsic functionality of the software tool, in particular "CATIA". To modify parameter values of a model, it is not necessary to recompile the application. Simply use the software's standard functions to modify parameters. Nevertheless, software tools organize the structure in relation to the construction history or represent the model in the form of affiliation tree.

然而，这种表示相对地偏离了与参数模型设计相关的技术问题的可操作方案。However, this representation deviates relatively from an operational solution to the technical problems associated with parametric model design.

于是，这对于一位非软件专业的使用者来说在只了解其希望实现的结果的情况下就能轻易地重新找出一个参数是相对困难的。Therefore, it is relatively difficult for a non-software professional user to easily find out a parameter again when he only knows the result he wishes to achieve.

发明内容Contents of the invention

本发明正是对此问题提供了一种解决方案。It is to this problem that the present invention provides a solution.

本发明旨在向非专业使用者提供一个与部件设计相关的技术问题的可操作方案中的结构参数编辑器，以便得到一个修改参数的简化界面，而不必修改源代码。The present invention aims to provide non-professional users with an editor of structural parameters in an operable solution to technical problems related to component design, in order to obtain a simplified interface for modifying parameters without having to modify the source code.

它作为一个或一套部件的三维几何模型的生成设备，所述模型以包含至少由一个命令参数确定的至少一个元素的规格树的形式图形表示在计算机屏幕上。It acts as a generating device of a three-dimensional geometric model of a component or a set of components, said model being represented graphically on a computer screen in the form of a specification tree containing at least one element determined by at least one command parameter.

根据本发明的通常定义，生成设备包含一个转换器，适于将所述规格树转换为一个用户图形界面，其中对于所述树中的至少一个现用元素关联一个对话框，所述对话框包含与所述现用元素的至少一个命令参数相对应的至少一个域，所述命令参数的调节可由用户借助一个参数编辑器进行修改，所述命令参数的每次调节显示在对话框的相应域中并自动执行规格树中对应的现用元素的命令参数的调节的修改。According to a general definition of the invention, the generation device comprises a converter adapted to convert said specification tree into a graphical user interface, wherein for at least one active element in said tree is associated a dialog box containing at least one field corresponding to at least one command parameter of said active element, the adjustment of said command parameter being modifiable by the user by means of a parameter editor, each adjustment of said command parameter being displayed in the corresponding field of the dialog box And the adjustment modification of the command parameter of the corresponding active element in the specification tree is executed automatically.

因此，利用本发明的对话框，一个用户可以轻易地直接修改现用元素的参数域的数值，而不必是一个CAD软件技术人员。而且，借助对话框的参数修改引起规格树中相应的修改。结果是，对一位非专业用户而言，对CAD软件规格树的现用元素的命令参数进行访问和修改会非常便利和简单。而且，利用本发明的参数结构的修改无需源代码的修改。Therefore, using the dialog box of the present invention, a user can easily and directly modify the value of the parameter field of the active element without being a CAD software technician. Furthermore, a parameter modification by means of a dialog box causes a corresponding modification in the specification tree. As a result, accessing and modifying the command parameters of the active elements of the specification tree of the CAD software is very convenient and simple for a non-expert user. Furthermore, modification of the parameter structure utilizing the present invention does not require modification of the source code.

根据一种实现方式，图形界面还包括一个包含相应现用元素几何特性的图形窗口，所述参数的调节直观地显示在上述图形窗口中。According to an implementation manner, the graphical interface further includes a graphical window containing geometric properties of corresponding active elements, and the adjustment of the parameters is intuitively displayed in the graphical window.

同样，通常被CAD软件专家定义且被非专业用户认为有趣的命令参数是在符合本发明的图形界面和/或对话框上直接可见且可修改的。Likewise, command parameters that are usually defined by CAD software experts and considered interesting by non-professional users are directly visible and modifiable on graphical interfaces and/or dialog boxes consistent with the present invention.

实际中，规格树的每个元素属于由终端节点和非终端节点形成的组。In practice, each element of the specification tree belongs to a group formed by terminal nodes and non-terminal nodes.

例如，在每个终端节点上关联一个用户图形窗口类的显示器和一个参数编辑器。For example, associate a user graphics window class display and a parameter editor with each terminal node.

同样的，在每个非终端节点上关联一个参数编辑器和多个选项标签(onglet)，在每个选项标签上关联一个子节点。Likewise, associate a parameter editor and multiple option tags (onglets) with each non-terminal node, and associate a child node with each option tag.

例如，对至少某些选项标签关联一个图形窗口。For example, associate a graphics window with at least some option labels.

按照另一种实现方式，参数编辑器还可以是一个脚本编辑器，其中脚本语言譬如是XML型标记语言。According to another implementation, the parameter editor can also be a script editor, wherein the script language is, for example, an XML-type markup language.

按照又一种实现方式，生成设备另外包含一个可以远距离交换参数域数值的通信装置用于与其他用户进行远距离协同工作。According to yet another implementation, the generating device additionally includes a communication device capable of remotely exchanging parameter field values for remote collaborative work with other users.

本发明同样提供一个与一个部件或一套部件相关的三维几何体的参数模型生成方法，所述模型以包含由至少一个命令参数确定的至少一个元素的规格树形式图形显示在计算机屏幕上。The invention also provides a method for generating a parametric model of a three-dimensional geometry associated with a part or a set of parts, said model being graphically displayed on a computer screen in the form of a specification tree comprising at least one element determined by at least one command parameter.

按照本发明的另一个方面，方法包括下列步骤：According to another aspect of the present invention, the method comprises the steps of:

-  将所述规格树转换成一个用户图形界面，其中所述树的至少一个现用元素关联一个对话框，该对话框包含与现用元素的至少一个命令参数相关联的至少一个域。- converting said specification tree into a graphical user interface, wherein at least one active element of said tree is associated with a dialog box containing at least one field associated with at least one command parameter of the active element.

-  自动改变规格树中相应现用元素命令参数的调节。- Automatically change the adjustment of the command parameter corresponding to the active element in the specification tree.

按照一种实现方式，方法还包括一步骤，此步骤中所述参数的调节被直观地显示在图形窗口中。According to an implementation, the method further includes a step, in which the adjustment of the parameter is visually displayed in a graphics window.

本发明同时旨在提供一种信息系统可读信息载体，特征在于它包含信息程序指令，当这一程序被一信息系统加载且执行时，使执行针对上述目的的生成方法。The present invention also aims to provide an information carrier readable by an information system, characterized in that it contains information program instructions, which, when this program is loaded and executed by an information system, cause the generation method for the above-mentioned purpose to be performed.

本发明同时旨在提供一种可拆卸的(amovible)信息载体，可部分或全部地被信息系统读取，其特征在于它包含信息程序指令，当这一程序被一信息系统加载且执行时，使执行针对上述目的的生成方法。The present invention also aims to provide a detachable (amovible) information carrier, which can be partially or completely read by an information system, and is characterized in that it contains information program instructions. When this program is loaded and executed by an information system, Make execute generate method for above purpose.

本发明最后旨在提供存储在信息载体上的计算机程序，所述程序包含指令，当这一程序被一信息系统加载且执行时，使执行针对前述目的的生成方法。The invention finally aims to provide a computer program stored on an information carrier, said program comprising instructions, which, when this program is loaded and executed by an information system, cause the execution of the generation method for the aforementioned purposes.

软盘可由任何一种信息载体替代，例如，光盘(CD ROM)或存储卡。通常的做法是，一种信息存储装置，可被计算机或微处理器识别，安装或并不安装在设备中，必要时可拆卸，适用于存储一个或多个程序，该程序在执行时可以实施根据本发明的方法。The floppy disk can be replaced by any kind of information carrier, for example, compact disc (CD ROM) or memory card. In general practice, an information storage device, identifiable by a computer or microprocessor, installed or not installed in a device, and detachable if necessary, suitable for storing one or more programs which, when executed, implement according to the method of the invention.

这一设备因而包含这一或这些信息程序的代码，例如被固化在专用集成电路上(ASIC)。This device thus contains the code of this or these information programs, for example embodied on an application specific integrated circuit (ASIC).

参照图3，显示了图1中航空器的三维数字模型的工作环境。我们再次看到航空器4的图形表示和规格树2。Referring to FIG. 3 , the working environment of the three-dimensional digital model of the aircraft in FIG. 1 is shown. Again we see the graphical representation ofaircraft 4 and thespecification tree 2.

当选择规格树2的其中一个现用元素，这里是元素“机身fuselage.1”20B，并激活位于工具栏18里的按钮或图标18A“参数编辑”时，又一个图形界面50出现在微计算机屏幕上，重叠显示在第一个图形界面4上。When selecting one of the active elements of thespecification tree 2, here the element "Fuselage. On the computer screen, the overlap is displayed on the firstgraphical interface 4 .

这个图形界面50是一个对话框，至少包括与命令参数有关的一部分54和必要时候出现的关于相应元素的几何体的一部分52。图形界面50包含用于模型20B“机身fuselage.1”的每一个元素的选项标签60。这些标签60被个体化为60A到60F，分别对应元素“全视图”，“主体”，“横切面”，“机舱”，“汽缸”和“尾部”。Thisgraphical interface 50 is a dialog box comprising at least apart 54 relating to the command parameters and apart 52 relating to the geometry of the corresponding element, which appears when necessary.Graphical interface 50 contains option tabs 60 for each element ofmodel 20B "Fuselage.1". These tags 60 are individualized as 60A to 60F, corresponding to the elements "full view", "body", "cross section", "nacelle", "cylinder" and "tail", respectively.

在部分54中，可看见一个对应选中标签的命令参数清单70，这里是对应“横切面”的标签60C。Insection 54, a command parameter list 70 can be seen corresponding to the selected tab, here thetab 60C corresponding to "Cross Section".

参数70被个体化为70A到70K。每一个参数70对应一个域80，域中数值可由用户借助于数值改变装置如一个升降器82或一个游标82H进行修改。每一个参数同样包括一个选择按钮84。Parameters 70 are individualized as 70A to 70K. Each parameter 70 corresponds to a field 80 in which the value can be modified by the user by means of value changing means such as a lifter 82 or aslider 82H. Each parameter also includes a selection button 84 .

图标18A是一个可以根据本发明发出显示对话框50的命令的快捷方式。这一命令生成一个参数编辑器，用于在结构上和功能上反映模型而无须直接依靠规格树或部件的构造历史。参数编辑器展示用于编辑模型的某些参数至少参数70的各个域80。域80与模型参数直接关联。Icon 18A is a shortcut that can issue a command to displaydialog box 50 in accordance with the present invention. This command generates a parameter editor for structurally and functionally reflecting the model without directly relying on the specification tree or the construction history of the part. The parameter editor presents various fields 80 for editing certain parameters of at least the parameters 70 of the model. Domain 80 is directly associated with model parameters.

图形界面50由三个按钮：确认按钮“OK”90A、应用按钮90B和取消按钮90C构成。Graphical interface 50 is composed of three buttons: confirmation button "OK" 90A, applybutton 90B and cancelbutton 90C.

参照图4，用户在对话框50的部分54中选择他想要在对话框50的部分52中处理、修改和/或可视化的参数。这里，用户选择对应于横切面机身高度的参数70A。记录在对应域80A中的原始数值这里是3000mm。用户使受对话框中部分52中的参数70A影响的几何部分可视化。Referring to FIG. 4 , the user selects insection 54 ofdialog 50 the parameters that he wants to process, modify and/or visualize insection 52 ofdialog 50 . Here, the user selects theparameter 70A corresponding to the cross-sectional fuselage height. The original value recorded in thecorresponding field 80A is here 3000 mm. The user visualizes the portion of geometry affected byparameter 70A insection 52 of the dialog.

参照图5，用户希望根据图4中显示的数值修改参数70A的调节数值。例如这里，他借助升降器82A修改参数70A关于机身横截面的高度值(新数值＝2000mm)。参数数值改变的效果在图形窗口52中被实时地(1至2秒钟)明显显示。Referring to FIG. 5 , the user wishes to modify the adjustment value ofparameter 70A according to the value shown in FIG. 4 . Here, for example, he modifies the value ofparameter 70A with respect to the height of the fuselage cross section (new value = 2000 mm) by means ofelevator 82A. The effect of changing the parameter value is visibly displayed in thegraphic window 52 in real time (1 to 2 seconds).

确认按钮90A(OK)的选择使得参数新数值自动加入到产品的全部元件中。Selection ofconfirmation button 90A (OK) causes the new value of the parameter to be automatically added to all components of the product.

参照图6，人们显然自动地观察到：参数70A数值借助于参考图5描述的对话框50的改变，引起规格树2和显示在图形界面4上的几何图相对于参照图1所述的工作环境2和4的相应改变(这里机身横截面缩小)。Referring to Fig. 6, one obviously automatically observes that the change of theparameter 70A value by means of thedialog box 50 described with reference to Fig. Corresponding changes forenvironments 2 and 4 (here the fuselage cross-section is reduced).

实际中，是一转换器将规格树2转换成一个用户图形界面50、52、54，其中至少一个现用元素，这里是图2至6中所述树2的现用元素20B，被关联一个对话框，该对话框包含至少一个与所述现用元素的至少一个命令参数70A关联的域80A。实际中，根据本发明需要转换器生成一个结构参数编辑器，它在与部件设计相关的技术问题的可操作方案中提供了可由非专业用户输入参数的域。In practice, a converter transforms thespecification tree 2 into agraphical user interface 50, 52, 54 in which at least one active element, here theactive element 20B of thetree 2 in FIGS. 2 to 6, is associated with a A dialog box containing at least onefield 80A associated with at least onecommand parameter 70A of said active element. In practice, the converter according to the invention is required to generate a structural parameter editor which provides fields for input of parameters by non-expert users in the operational solution of technical problems related to component design.

命令参数70A的调节是可由一位CAD软件非专业用户通过选择图标18A启动根据本发明的参数编辑器修改的。实际中，参数编辑器利用CAD软件中的可用参数编辑器的自带功能。Adjustment of thecommand parameter 70A is modifiable by a non-expert user of CAD software by selecting theicon 18A to activate the parameter editor according to the present invention. In practice, the parameter editor utilizes the native functionality of the parameter editors available in the CAD software.

根据本发明的参数编辑器借助所述自带功能组织和结构化对话框50中的模型的参数。The parameter editor according to the invention organizes and structures the parameters of the model in thedialog box 50 by means of said built-in functions.

所述命令参数的每一次调节直观地被显示在相应的域80并自动引起规格树2中相应现用元素的命令参数调节的变化。因此，一位用户可以轻易并直接地通过对话框修改参数的数值。Each adjustment of said command parameter is intuitively displayed in the corresponding field 80 and automatically causes a change in the adjustment of the command parameter of the corresponding active element in thespecification tree 2 . Thus, a user can easily and directly modify the value of a parameter via a dialog box.

图形窗口52包括相应现用元素20B的几何图，所述参数的调节被显示在所述图形窗口52，它使非专业用户可直观地确认参数数值的变化效果。Thegraphic window 52 includes a geometric diagram of the correspondingactive element 20B, and the adjustment of the parameters is displayed in thegraphic window 52, which enables non-professional users to visually confirm the effect of the change of the parameter value.

实际中，转换器根据所选择的编辑和转换规则转转每个现用元素成一个对话框。In practice, the converter converts each active element into a dialog according to the selected editing and conversion rules.

例如，规格树2中的每个元素20A，20B，20C，20D，20E属于由终端节点和非终端节点构成的组。在每一个终端节点上关联一个用户图形窗口型可视显示器52和一个参数编辑器18A。在每一个非终端节点上关联一个参数编辑器18A和多个标签60，每一个标签60关联一个子节点62。For example, eachelement 20A, 20B, 20C, 20D, 20E in thespecification tree 2 belongs to a group consisting of a terminal node and a non-terminal node. Associated with each terminal node is a user graphical window typevisual display 52 and aparameter editor 18A. Associated with each non-terminal node is aparameter editor 18A and a plurality of tags 60 , each tag 60 being associated with a child node 62 .

实际中，参数编辑器还是一个脚本编辑器，例如脚本语言是一种XML型标记语言。In practice, the parameter editor is also a script editor, for example, the script language is an XML markup language.

因而，由于通信接口106，可以远距离，以XML文件形式，交换参数域80的数值。这样一种交换允许通过交换仅包含参数的修改的文本或脚本形式的小文件，来与其它用户进行远距离协同工作。Thus, thanks to thecommunication interface 106, the value of the parameter field 80 can be exchanged remotely, in the form of an XML file. Such an exchange allows remote collaborative work with other users by exchanging small files in the form of modified text or scripts containing only parameters.

转换器在实际中体现为被一种扩展机制附加到CAD软件的一系列补充软件功能形式，被称为“插件”。这种扩展在物理上由文本文件、图标或CAD软件文件形式的一系列动态库和资源文件组成。In practice, the converter is embodied as a series of supplementary software functions added to the CAD software by an extension mechanism, which is called "plug-in". This extension physically consists of a series of dynamic libraries and resource files in the form of text files, icons or CAD software files.

编辑规则可区分两种类别的命令参数：可修改参数和不可修改参数。Editing rules distinguish two categories of command parameters: modifiable parameters and non-modifiable parameters.

根据本发明的转换软件在打开一个已经被CAD软件如Catia V5版创建的三维模型后被启动。转换软件可轻易并直接地修改三维模型的参数而不要求CAD软件的深入了解且不会造成对源代码的修改。The conversion software according to the invention is activated after opening a three-dimensional model that has been created by CAD software such as Catia V5 edition. The conversion software can easily and directly modify the parameters of the 3D model without requiring in-depth knowledge of the CAD software and without causing modifications to the source code.
