The first target of the macro-parametric translation is simple mechanical parts.
We can assume that commands required to model simple parts or features are similar enough to define a set of standard modeling commands. There are many similar commands such as protrusion or revolve. Each CAD system has its own set of modeling commands however they have the common goal of providing an efficient user interface to define geometry. The proposed modeling commands are defined from a common set of user commands of commercial CAD systems such as CATIA, Pro/E, UG, IDEAS, SolidWorks, and SolidEdge. Based on the translation experiments of test models, the set of standard modeling commands can be finalized. Mapping relationships between the standard commands and commands of commercial CAD systems are defined. A set of standard modeling commands has been generated.
These modeling commands are grouped into several types. Modeling commands of famous commercial CAD systems have been analyzed. To exchange CAD models using the macro-parametric approach, a set of standard modeling commands has been developed. Neutral Commands or a set of standard modeling commands
