步驟三維CAD文件通常被分類為3D圖像文件,並且這些步驟的3D CAD文件被集成用於STP文件格式編碼規格。落實到這些STEP 3D CAD文件的文本格式標準也符合STEP應用協議ISO 10303-2xx。這些STEP 3D CAD文件是專門被稱為包括用於機械CAD設計,數字3D元素的3D裝配數據。這些STEP 3D CAD文件都保存在STP文件格式,並附加了的.stp擴展。這些STEP 3D CAD文件也被視為與這些STP文件的支持來實現機械CAD應用的三維產品模型數據交換文件。發明者融合CAD軟件是由歐特克開發,並與這些STP文件的支持來實現。這意味著在基於Microsoft Windows的系統上運行的計算機可以被用來安裝發明家融合CAD程序來實現支持到系統的創建,打開和查看這些STP文件的內容。

Dassault Systemes CATIA is an application that was programmed using C++. This software is used to design aircrafts, such as the mirage jet fighter. The CATIA program can be used in designing automotives, ships, plant designs and packaged goods. It can also be used in architecture, life science, construction, designing of new gadgets and industrial equipment. Catia can render 3D parts, sheet metal, tooling parts of mechanical assemblies in every detail, and this software aids in intelligent engineering systems. This software runs in Microsoft platforms like Windows Xp, Windows Vista and Windows 7. The Hard Drive should have at least 2 GB of available storage space.
