7.4.1-Release¶

BlueQuartz Software is proud to release version 7.4.1 of DREAM3D-NX. This update contains key bug fixes, enhancements and introduces a some new features.

Release Date: March 23 2026

What's New and Fixed in DREAM3D-NX Version 7.4.1¶

Easier Editing of Visualization Text Annotations

Just double-click on the annotation and an editing box will pop up.

Faster 2D Plotting

Completely rewritten 2D Plotting code that emphasizes speed and export. Now you can export your charts as .svg files making them instantly publication ready!

Per Geometry Default Data Views

Now you can define which Data View you want for each kind of geometry. Accessed through the preferences.

Interactive Orientation Widget

Click on the orientation widget in the lower left corner to instantly snap to a camera angle.

Mini Histogram View

Display a mini-histogram in the visualization view of the actively shown data.

Updated Color Spreadsheet View

Combine the auto-column-size + colored background to bring your data alive!

2D Slice View Linking

Link 2D Image/Slice View Slice Number Settings between views

Read and Crop a Stack of Images

Newly added to the "Read Iamges [3D Stack]" filter, you can crop as you read the images saving time and memory.

Other Important Enhancements and Bug fixes¶

5 brand new filters added
Lots of quality-of-life to make using DREAM3D-NX easier
Performance enhancements on a number of filters

Known Issues¶

Synthetic Building Filters are not yet implemented
Long visualization operations can lock up the GUI. Please be patient for those operations to end.
Compute Feature Centroids will not respect periodic boundaries in a model
The Anaconda version will not save your GUI window layout correctly. The workaround is to create a layout to your liking and save it as a preset.
Computing Volumes from Triangle Features will not work correctly unless all triangle normals are consistent and the surface mesh is watertight.
