The IGES Reader provides full access to the B-rep and View Data stored within a particular IGES file. A file does not need to have a particular extension to be read correctly by HOOPS Exchange however the file extensions of IGES files that you can expect to be loaded by HOOPS Exchange are:
Our readers are updated to the latest released version within 90 days of the release of the authoring software. You can see the exact version supported in the current release here.
The full assembly tree definition is provided however referenced files are not currently supported. Incremental load is not supported by our IGES reader.
The list of supported surface types:
Rational b-spline surface
Parametric spline surface
Surface of revolution
Right circular cylindrical surface
Right circular conical surface
The list of supported curve types:
Rational b-spline curve
Curve on a parametric surface
Parametric spline curve
This visualization data for this format is generated by the HOOPS Exchange tessellation engine.
Views are supported, however, authoring applications very rarely export IGES data with views.
This concept is not supported by IGES.
Our IGES reader does significant effort to correct problems with corrupt or poorly defined data.
Some of the things done here include fixing basic problems with corrupt files, correcting orientation problems, closing open loops and adjusting vertex tolerances.
A3DAsmModelFileSew() function is available to developers who want all surfaces which share a common edge to be joined together.
