IGES is an international standard which defines a neutral file format for the representation of geometric and topological data. Parasolid IGES is a Parasolid-powered component library that offers a robust and reliable solution for bi-directional translation of geometric data between Parasolid-powered applications and other heterogeneous CAD systems through IGES files.

JAMA-IS is an IGES data exchange protocol established for the Japanese automobile industry to realise smooth data interchange among dissimilar CAD/CAM systems. Parasolid IGES supports JAMA-IS version 1.04

Parasolid IGES can be easily integrated into any Parasolid-powered application using its well documented API.

Features

  • Designed to provide high quality bi-directional transfer/exchange of geometric and topological data between IGES and Parasolid
  • Supports Trimmed surfaces and Solids i.e. Manifold Solid B-Rep Object (MSBO)
  • Provides user tunable parameters to control the transfer of data.
  • Provides call back functions to monitor conversion progress and to abort the conversion if required.
  • Provides automatic stitching (sewing) of loose faces into sheet/solid models.
  • Preserves entity, label, layer and color attributes during translation.
  • Units are automatically converted to represent IGES entities in meters in PARASOLID
  • Functions have been provided to monitor and interrupt the IGES conversion process.
  • Strict conformance to the IGES format.
  • Provides a well documented API for easy integration with Parasolid-powered CAD/CAM/CAE applications.
  • The reader module can pre-scan the directory section of an IGES file so that its contents can be determined without having to read all the data.
  • The reader module carries out operations in three phases - syntax checking of input IGES files, conversion of IGES entities and optionally sewing of surfaces:
  • Syntax checking. To ensure integrity of the input IGES file, the reader module scans the input IGES file and validates its syntax in the first phase.
  • Conversion. In the second phase, the reader scans all entities in the given IGES file in order to find the root nodes and subordinate nodes. Next, for each entity, its name, entity type and directory entry (DE)-pointer is found out. The conversion process that converts IGES entities to corresponding PARASOLID entities follows this. Then the converted PARASOLID entities are scaled to meters.
  • Sewing. Faces, which are obtained during the conversion process, are sewed (stitched) to form solid and sheet bodies. The sewing is an optional phase of the reader module. The reader recognizes the different "flavors" of IGES that some CAD systems write. Turning a flavor filter on or off is under user-control.
  • Callback functions offer feedback during the reading and writing process. These facilitate the creation of progress meters.
