Introduction to Programming the SolidWorks API with Visual Basic James Lewontin Bitwright Software Tools for Programming the SolidWorks API with Visual Basic return = variableName.method ([parms]) return = variableName.method ([parms]) Navigate the SolidWorks API Object Hierarchy: “Dig Down” Traverse Select Objects Introduction to Programming the SolidWorks API with Visual Basic James Lewontin Bitwright Software Tools for Programming the SolidWorks API with Visual Basic Acronym “API” is an acronym for “Application Programming Interface” “API” is also used to mean any individual function in the API, as in “The new Service Pack includes six new APIs” Functional The API is a way for computer programs to control a SolidWorks session The User Interface is way for human beings to control a SolidWorks session The two interfaces are very much alike; it is generally true that if you can do something in one interface, you can also do it in the other. There are exceptions: When you can do something in the UI that you can’t do in the API, it is generally connected with a dialog: e.g. “Insert Object” There are many things that you can do in the API that don’t make sense in the UI: e.g. get a view Xform Structural SolidWorks is an Object Oriented program (usually defined per Encapsulation, Polymorphism, Inheritance) SW’s main organizational unit is the “Object” An Object A package of computer code containing procedures and data (“methods” and “properties”) Represents something in the physical of conceptual world Objects have hierarchical relations – e.g. “Hotel”, “Conference Room”, “Chair” SW includes a “bunch” of patterns for objects (“classes”) E.g. “Body”, “Face”, “Edge”, “Vertex” Each pattern includes enough information to create (“instantiate”) an object SW includes a system for Object management Creates and destroys objects when needed A SolidWo
