Gateway for 3D Data 6​.1​.1 release notes

These release notes describe enhancements to and include resolved and known issues where applicable.

This release contains a patch release of AVEVA Gateway for 3D Data 6.1.1, which replaces the full release of AVEVA Gateway for 3D Data 6.1.

New features and enhancements

• Migrate to .NET 10.0:

  The Gateway is upgraded from .NET 8.0 to .NET 10 to enhance performance, strengthen security, and ensure long-term support.

  This release supports .NET 10, as .NET 8 will reach end of Microsoft support on 10 Nov 2026.

Resolved issues

No open issues were resolved in this release.

Known issues

There are no known issues in this release.

Expectations and Limitations

The following expectations and limitations should be considered for this release of the Gateway:

STEP limitation – memory leak

A memory leak has been identified when processing a particular set of STEP files using the STEP extractor only, which may lead to increased memory usage. A permanent fix is planned for a future release. As a workaround, we recommend enabling <SeparateProcesses>true</SeparateProcesses> in the project configuration file for the STEP extractor. This will ensure stable performance and prevent excessive memory consumption.

IFC limitation – Bezier curves

IFC 4 files containing these entities cannot be processed:

• IFCBEZIERCURVE

• IFCRATIONALBEZIERCURVE

Navisworks limitation - layer attributes

When NWD files are derived from an import of MicroStation 3D models, the 'layer' attributes of objects are not extracted by the Gateway. Navisworks files derived from other 3D sources such as AutoCAD and IFC are unaffected by this limitation.

General limitation – use of commas in Non-English user locales

When the Gateway is installed on a system where the user has selected a non-English locale that uses a comma as the decimal separator (that is, a number 123.45 in a Windows system with a French locale would be expressed as 123,45), the Gateway does not interpret such numbering formats from input sources and configurations nor does it export them into output files.

System requirements

Operating system prerequisites

The Operating systems prerequisites for the Gateway are listed below:

Note: The recommended/supported hardware and software configurations are constantly subject to review, so please consult the AVEVA support (https://www.aveva.com/en/support-and-success) for the latest recommendations.

Gateway prerequisites

The prerequisites for this Gateway release are as follows:

• Microsoft .NET Desktop Runtime 10 (64-bit)

• Microsoft Visual C++ Redistributable 2015-2022 (64-bit)

• Disk Space – When the Gateway processes large models it requires disk space to store temporary graphics files. For example, to create a 7 GB ZGL it requires 100 GB of temporary space. Processing times will also be extended if the server isn’t using a Solid-State Drive. Note that the size of the ZGL must be < 9 GB when using 3DVS in AIM.

• RAM - Huge input files may take significant time to process if the memory required by the Gateway process nears the limit of the RAM, as the Windows system will then start memory paging. For example:

  • Input NWD files up to 500 MB will require 32 GB of RAM and NWD files above 500 MB will require 64 GB RAM

  • Input IFC files up to 4 GB will require 64 GB RAM

    Therefore, if you expect to be processing such large files you should ensure the Gateway server has enough RAM to avoid memory paging.

    Note: Neither the AVEVA Licensing System nor LaaS are required for this version.

Compatibility information

For detailed software requirements and supported software, see the Software Requirements section in the AVEVA Gateway for 3D Data online help.

To Install product release: Please read the installation section of the online help (under the Get Started page of the AVEVA Gateway for 3D Data) or contact local support.

Note: Before this AVEVA Gateway for 3D Data 6.1.1 is installed, please ensure that any previous version of AVEVA Gateway for 3D Data is uninstalled.
