2026 Platform Releases

v3.260227

Finite Element Analysis

• Binary Export/Import for FEA Results: Export and import FEA analysis results to transfer models with completed analysis to another computer. Since results are stored locally in browser IndexedDB rather than the cloud, this feature enables sharing analysis results across machines.

• 6x6 Equivalent Stiffness Matrix: Added comprehensive equivalent stiffness matrix calculation with flexibility matrix reporting (unaveraged and averaged).

• Auto-detect Floor Stiffness: Automatic detection of floor stiffness for softening curves with improved stiffness editor UI.

• Spring Activation Displacements: New boolean property to bypass pre-activation displacement subtraction for verifying activation-aware displacement logic.

• Spring Force Recovery Fix: Fixed spring force recovery to consider displacements after element activation and zero out previous force for springs that just became active.

• Nonlinear Curve Sorting Fix: Sort nonlinear curves by displacement instead of force to handle user input errors gracefully.

• Node Merge Priority: Prioritize keeping nodes with 6x6 stiffness matrix during same-location merge operations.

Code Editor

• Enhanced CORE Object IntelliSense: Added inline parameter suggestions and example children for improved code completion experience.

• Template Params Fix: Fixed IntelliSense to get params from template object correctly.

3D Rendering

• Cross-Slope Rendering Fix: Resolved rendering artifacts in deck surfaces with cross-slope geometry.

Performance

• xxHash for Geometry Cache: Use xxHash for geometry cache keys for faster lookups.

• Faster Stage Filtering: Speed up constructed-only stage filtering in FEA.

• JsParser Optimization: Optimized JsParser.Execute with property caching and frequency ordering.

• Compilation Performance: Faster compilation with fast-path and O(1) lookups.

• GetIdentifierValue Optimization: Skip GetObjA when param found at distance 0 for faster parameter resolution.

• Reduced GC Pressure: Reuse Float64Array buffer in Rotate3d operations.

ParamML

• insertinto Function: New JsParser array function with dual-lambda support for advanced array operations.

• trimPolyline Function: New function to trim polylines with support for negative offset to extend polylines.

• Z-Coordinate Interpolation: Added z-coordinate interpolation for XY plane intersections.

• Alignment Projection Enhancements: Added refinement and includeControlStations arguments to alignProjection function.

• US Survey Foot Support: Added US Survey Foot (ftUS) unit string representation to ToStrLength.

Import/Export

• DGN Export Error Handling: Improved DGN Writer error handling with client-side validation for custom properties.

• ExtObj Validation: Improved validation for missing object references in external objects.

User Interface

• Isolate (Picked) Action: New spreadsheet cell action for object reference columns to quickly isolate referenced objects.

• Spreadsheet Row Version Fix: Fixed project object version when adding new spreadsheet rows.

Project Management

• Guard/Reference Ordering Fix: Fixed operation ordering to remove refs before guarding and unguard before adding refs.

• Guarded Objects Fix: Fixed guarded objects being incorrectly added to references.

• ParamDesc Migration: Added ParamDesc support to ParamValueSet for version migration.

Geometry

• Polygon-Line Intersection: Implemented polygon-line intersection handling with optimized line filtering logic.

• Line Projection Optimization: Reduced line projection to a single point for constraint points array.

v3.260204

DGN Seed File Configuration

• Custom Seed File Support: You can now upload and assign your own MicroStation seed files for DGN export, giving you control over levels and line styles in the exported DGN. See DGN Seed File Configuration for details.

Finite Element Analysis

• Partial Completion Handling: Nonlinear FEA analysis now supports partial completion, preserving results from completed load steps when analysis is interrupted or fails to converge.

• Cancel Confirmation Dialog: Added a confirmation dialog when canceling a running FEA analysis to prevent accidental interruptions.

• Download Log Button: Added a download log button to the analysis completion and FEA logs dialog.

• Auto-Scroll Resume: Added a floating button to resume auto-scroll in the FEA log textarea when the user manually scrolls.

• Spring Gap Handling: Fixed penalty stiffness calculation for springs with gaps.

Section Analysis

• Phi Factor Improvement: Improved phi factor interpolation in the interaction diagram transition zone.

Alignment and 3D Rendering

• COG Support in Alignment: Enhanced alignLine function with center of gravity (COG) support and configurable alignment rules.

• Skewed Station Solver: Added skewed station solver with intersection detection for improved 3D rendering of skewed structures.

• Control Locations: Enhanced alignment control location management and line splitting functions.

Sections

• Custom Variation Paths: Added custom variation path support for non-prismatic sections, enabling more flexible section transitions.

• Station-Dependent Shape Coordinates: The sectionShapeCoords function is now station-dependent, returning shape coordinates that vary along the member length.

• Circle Section Support: Circle-type sections are now supported for station-dependent section generation.

ParamML

• ClosestPointOnPolyline Function: New ParamML function to find the closest point on a polyline from a given location.

• volume() Surface3D Support: The volume() function now supports Surface3D geometry types.

• formatstation Function: New FormatStation utility and formatstation ParamML function for formatting station values.

• makestadep Expansion: The makestadep function has been expanded with additional capabilities.

• Gross Area Fix: Fixed RebarCircularLayout being incorrectly included in gross area calculation.

Import/Export

• LandXML Import: Improved azimuth calculation and added multi-file support for LandXML imports. Fixed curve StartAzimuth direction handling.

• LARSA4D Import: Fixed sanitization of illegal characters in names during LARSA4D import.

• CSi Export: Added support for exporting FE groups to CSi Link format.

• IFC Fixes: Various bug fixes for IFC export robustness.

User Interface

• Work Point Picking: Introduced Work Point picking feature with parametric and boundary point support for precise point selection.

• Delete Objects UX: Improved delete objects experience with progress feedback for large deletion operations.

• Branch Search: Added search box to the branch UI for finding objects.

• Spreadsheet Fix: Fixed spreadsheet cell staying active when clicking cell actions or scrolling.

• TypeParamSelect: Added TypeParamSelect cell action for ParamInterface spreadsheets, enabling type-based parameter selection.

Project Management

• GCS Sync: Projects now automatically sync their Geographic Coordinate System (GCS) from the source project if the local project doesn't have one defined.

• Project Duplication Fix: Fixed project duplication issues caused by PopulateExtends race condition and IndexedDB caching.

• Project Folder UI: Improved project folder interface with better validation.

Performance

• Faster Local Data Access: Optimized how the platform reads locally cached data (used extensively by FEA and project storage), resulting in up to 38x faster data retrieval.

• Spreadsheet Copy: Improved large spreadsheet copy operations using time-based yielding to prevent UI freezes.

• Expensive Parameters: Simplified and improved expensive parameter computation to require compiled project, with expression-based cache keys.
