# 7.4.1

This is the 7.4.1 release. Below are listed the bug fixes and feature additions that have gone into this release.

## 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.

## Feature & Bug Fixes of Note

- 5 new filters: Hierarchical Smooth, Compute Grouping Density, Extract Feature Boundaries 2D, Create Vertex Geometry from Orientations, Write LAMMPS file
- Initial volume rendering is substantially faster now with larger data sets (>10GB)
- Over 100 bug fixes and feature enhancements
- Double click on Text or Caption Annotations to edit
- Match ParaView when right-click zoom in/out
- All new 2D Plotting library with substantial speed increase
- Auto-select single visible geometry when switching active visualization view
- New Interactive Orientation Marker
- Active Array in Visualization module can now show a mini-histogram
- Image annotations can now be flipped horizontally and vertically
- Add automatic decimation for all vis data views
- PERF: InterpolatePointCloudToRegularGrid now calculates stats on-the-fly
- ReadZeissTxmFile - Add the ability to crop the incoming geometry.
