Release Note

HiNc Packages Version 3.1.160

Fix NC optimization R-format arc interpolation with negative R values (follow-up to v158 R-format arc fix)
Fix cubetree construction defect when a triangle edge passes through a wire corner
Mech Builder: geometry (STL) file picker for anchored transformation now offers Project directory in addition to Resource directory in Blazor GUI.
Rename XML IO utilities: XmlSourceAndFile<T> → FileRefSource<T>, CombineAsSubDirectory → GetResourceDirectory, MakeXmlSourceWithRebaseFile → MakeXmlSourceToFileRef

Fix G53.1 tool height compensation behavior: replace NcEnv.SetToolHeightCompensationOnFeatureNormal configuration with automatic detection via NC flag state
Make EnableIntegerShrinkOnPositionCommand configurable via project settings (previously hard-coded by CNC brand, now defaults to false with XML IO support)
Fix NC optimization splitting R-format arcs (G02/G03 with R parameter) by converting to IJK format, since R sign meaning does not apply correctly to individual fragments
Fix step.csv reading crash on null or malformed values
Fix XML IO sub-base directory not applied in some project file operations
Improve CSV actual time parsing to support DateTime format in addition to TimeSpan (see 執行CSV檔)
Fix CSV title parsing to trim surrounding quotes

Fix G68 coordinate rotation transformation for non-origin rotation centers
Fix NC optimization arc/circle offset when splitting arc fragments across multiple lines
Fix optimization rotation code jumping at ±180° cycle boundary by applying cyclic angle comparison
Fix RTCP on unmatched tool offset
Fix blocking issue when time-mapping file not found
Fix FlagsText always null after NC parser refactoring

Add cubetree geometry defect scanning (ScanRuntimeGeomInfDefect) and clearing (ClearDefectDisplayee) for detecting and visualizing geometry anomalies in workpieces (see 幾何缺陷掃描)
Upgrade internal fraction representation to float128 precision for improved cubetree geometry accuracy and numerical stability
Refactor messaging system from IMessageHost to standard IProgress<T> pattern; <xref:Hi.MachiningProcs.SessionMessageHost> now implements IProgress<T>, and all messaging methods renamed from Add* to Report* (e.g., AddProgress → ReportProgress)
Fix cubetree initialization crash
Improve postprocess precision by applying sin–cos parameterization instead of direct angle-based formulation for rotary axis numerical solving in XyzabcSolver
Add asynchronous anchor solid preparation on project load for improved startup performance

Enhance Siemens Sinumerik support:
- Siemens CYCLE800 coordinate transform and reset

Fix Siemens TRAFOOF plain rotation coordinate transform issue
Fix Siemens coordinate transform for successive file running
Fix relief face collision floating-point precision issue
Replace MongoDB with SQLite for local step data storage (significant package size reduction)
Add machining and motion resolution dynamic adjustment functions

Rename mapping API for clearer naming:
- ReadCsvByTimeInterpolation → MapSingleByCsvFile (one-to-one mapping)
- MapByActualTime → MapSeriesByCsvFile (one-to-many mapping)
Rename CSV column prefix Spindle to Holder for sensor data mapping
Unify CSV column tags to MappingUtil for consistent data mapping
Fix ChartRange manipulation to be time-based instead of step-based for more accurate time chart display
Tune thread priority for machining parallel processing to improve UI responsiveness during simulation
Various code cleanup and improvements

Separate resource files (Resource, wwwroot, Doc) to HiNc-Resource nuget package for smaller package size
Add ScaledFeedPerCycle function for scaled feed-per-cycle machining motion resolution
Upgrade target framework to .NET 10.0
