IDA-STEP v4IDA-STEP is a new generation of standards-based tools from DCT Co., Ltd. IDA-STEP is a fully modular application - you can create your own perfect IDA-STEP application for various data viewing and management purposes.

IDA-STEP is based on international standard ISO 10303 (STEP) and supports various kinds of STEP data. With the free IDA-STEP Viewer Basic component, IDA-STEP is capable of viewing 3D/2D models, PCB/PCA, PDM and other data.

When extended with available components IDA-STEP can provide data management and creation capabilities, import from other CAD systems and export to various file formats. Components for IDA-STEP are constantly being developed to provide new functionality to the application and update the existing components.

IDA-STEP is a fully modular application. Its functionality depends on the installed components, which may complement each other or provide totally different functions.

There are various components currently available for IDA-STEP:

  • Viewer components to display various STEP data (3D models, PCB/PCA data, PDM data, etc);
  • Editor components to create and manage PDM data, edit PCB layer stack data, etc;
  • Import components to import data from various CAD systems into IDA-STEP;
  • Export components to export data from IDA-STEP to various formats.

Only the required components can be installed thus allowing to create a required IDA-STEP application without unnecessary features.

IDA-STEP is based on an international standard ISO 10303 (STEP), which defines the standard product data representation and exchange. This architecture gives many advantages, such as universal data exchange, long-time archiving, data integrity and accessibility and more.

IDA-STEP is based on STEP modular approach (ISO 10303-1xxx), combining mechanics, automotive, electronics and electrics in one consistent set of data models. These combined data models wrap up the functionality of many STEP Application Protocols, including AP201, 202, 203, 210, 214, 236, 239, 242 and more.

The focus for IDA-STEP is to support core capabilities of the Application Protocols:

  • AP203: Configuration controlled 3D designs of mechanical parts and assemblies;
  • AP210: Electronic assembly, interconnect and packaging design;
  • AP214: Electrotechnical design and installation;
  • AP242: Managed Model Based 3D Engineering (currently in Committee Draft, will replace AP203 and AP214).
