ObjectSpecsModeler:Mechanical feature Architecture:Implement the feature behaviors * Interfaces are implemented through the Object Modeler extension mechanism * At last you will need to: - Encapsulate in your own interfaces the access to the feature's attributes - Provide the build mechanism for your feature * Also you want to implement some DS interfaces to further integrate your feature in CAT..

Mechanical feature inheritance : Public feature * MechanicalFeature - Feature without topology/geometry - Stores only data but can display visualization * GSMTool - for wireframe or surface root feature * GSMGeom or GeometricalElement3D - Applied by computing a wire frame or a surface feature ex: Point, curve or surface * MechanicalFormFeature - Applied by computing a form (or footprint), and op..

User Catalog management * Catalog files are dedicated to store feature definition (StartUp) * A catalog may store any number of StartUps * Once created a catalog should never be deleted - In fact a catalog has a unique ID which is used to identify the StartUps it contains. When a catalog is deleted and recreated, existing instances of every feature will still reference the old catalog ID. - inst..

Feature Instantiation * To Create an instance, - Open the catalog in read only: . use AccessCatalog method defined in CATCatalogFactoryServices.h - Retrieve the StartUp - Instantiate the StartUp . use the CATISpecObject::Instantiate method - Set attribute values * Open catalog CATIContainer * piSpecCont=...; CATUnicodeString catalogName = "MyCatalog.CATfct"; CATUnicodeString clientID = "ID"; CAT..

Catalog Definition * Create a new catalog - suffix : CATfct - Must be located in the CNEXT\resources\graphic directory of your framework - Use the CreateCaltalog method definded in header file CATCatalogFactoryServices.h CATUnicodeString catalogName = "TestCat.CATfct"; CATICatalog * piTestCatalog = NULL; HRESULT hr= ::CreateCatalog(&catalogName, &piTestCatalog); CATUnicodeString clientId = "..."..

Process to define a new feature * Design your StartUp - Define the reference data structure . Create or Upgrade catalog . Create the startup . Define the startup attributes . Save the catalog * Implement the different behaviors - Provide the implementations for the inheritance to be supported by the feature through Object Modeler extension - If needed, provide the Build mechanism * Create instan..

Feature instantiation and persistency * A feature is initiated from its StartUp that is retrieved from the catalog * The instance will be an exact copy of the startup and will retain any attributes with their initial default values * Because a feature ia a late type, the StartUp is retrieved from the catalog at Run-Time and it is instantiated in order to create a new feature * To be persistent a..

Workshop, Workbench, Addin * Workshop : 주어진 document type에 대한 common command * workbench : specilized command * addin : 존재하는 workbench의 toolbar 혹은 menu를 대표하는 것

위키피디아에서 가져옴 검색어 : BRep In computer-aided design, boundary representation—often abbreviated as B-rep or BREP—is a method for representing shapes using the limits. A solid is represented as a collection of connected surface elements, the boundary between solid and non-solid. The basic method was developed independently in the early 1970s by Ian Braid in Cambridge (for CAD) and Baumgart in America ..

A Factory is a special object that contains methods dedicated to object Creation. 팩토리는 오브젝트 생성에 기여하는 메소드를 갖고 있는 특별한 오브젝트이다. The Factory creates an implementation object and returns an interface object on it. 그 팩토리는 implementation object를 생성하고 그것에 접근하는 interface object 를 반환한다. The factory minimizes the coupling since the client application doesn't manipulate andy implementation instance The objec..
