Jonathon Broughton	659a29a294	Improves property value conversion and extraction (#1183 ) * Refactors property extraction to use model units Uses the model's units when extracting properties to ensure consistency and accuracy of converted values. Extracts property sets as a static function to provide re-usability without the class instance. * Refactors Revit category extraction Improves Revit category extraction by utilizing UI units for property conversion, ensuring consistent unit handling. Additionally, refactors the extractor to a static class. * Improves property conversion and handling Introduces robust property conversion and handling logic. Leverages user interface units for length, area, and volume property conversions, ensuring consistency with the Navisworks UI. Enhances property data handling by using dictionaries to represent numerical properties with associated units, providing more context for downstream applications. Adds property name sanitization to ensure compatibility with Speckle's object model. * Removes the unused `Speckle.Converter.Navisworks.Helpers` import from the PropertySetsExtractor class to reduce clutter and improve code maintainability. Relates to CNX-2784 * Standardizes numerical property dictionary creation. Simplifies the creation of numerical property dictionaries by removing the `internalDefinitionName` parameter from the `NumObj` method. This ensures a consistent format for numerical properties across the connector. Relates to CNX-2784 * Refactors property conversion to service Moves property conversion logic into a dedicated service. This improves code organization and testability and allows to reuse logic and manage UI units consistently. * Refactors property conversion for consistency Standardizes property conversion by introducing a dedicated `IPropertyConverter` service. This change ensures consistent handling of property values across different extractors, improving data accuracy and reducing inconsistencies in quantity extraction. It also adds resets of the property converter to ensure clean conversions for each item.

This improves the separation of concerns and makes the code more maintainable and testable. Relates to CNX-2784 * Fixes unit label typos. Corrects minor spelling errors in the unit labels for centimeters, millimeters, micrometers, and kilometers. Relates to CNX-2784 * Ensures correct units are used on send Uses the UI Units Cache service to ensure the correct units are being applied to objects when sending them to Speckle. Relates to CNX-2784 * Enhances the property helper functionality to support additional features.

Jonathon Broughton	1ffeddbc2c	Implements geometry instancing and optimization in Navisworks connector (#1188 ) * Introduces shared geometry store service Creates a singleton service for deduplicating geometry during conversion. This service stores mesh objects, preventing redundant processing of identical geometries by leveraging application IDs. It uses a dictionary and a hash set to optimize lookup and storage, and includes thread safety mechanisms. * Adds instance store manager for geometry Introduces an instance store manager to handle shared geometry, which includes separate stores for geometry definitions and instance proxies. This change prepares for the implementation of an instancing pattern compatible with .NET Framework. It also registers settings from a factory to resolve conversion settings. * Adds shared project file for Navisworks converter Introduces a shared project file for the Navisworks converter, promoting code reuse and consistency across different Navisworks converter implementations. This file includes common data extractors, data handlers, helpers, services, and settings, reducing duplication and improving maintainability. * Implements geometry instancing for Navisworks Adds geometry instancing to improve performance and reduce data size when converting Navisworks models with shared geometry. It identifies shared geometries based on fragment paths, extracts the base geometry once, and creates instance references with transforms. This reduces data duplication and improves loading times in Speckle. Improves handling of COM array data for fragment ID generation and includes comprehensive logging for debugging instancing issues. * Introduces instance store management Adds a service to manage shared geometry and instance definition proxies. This system uses two stores for geometry definitions and their instance proxies, facilitating efficient handling of shared geometry. It provides methods for adding, retrieving, and clearing geometries, ensuring deduplication and optimized memory usage. * Refactors display value extraction Streamlines display value extraction by injecting the geometry converter. This change simplifies the DisplayValueExtractor by removing its dependencies on settings and logging. It now directly uses a GeometryToSpeckleConverter instance, which is passed in, for converting model item geometry. * Adds instance geometry support to Navisworks connector Introduces instance geometry handling for more efficient and accurate Navisworks data streams. This includes: - Scoping the `InstanceStoreManager` to each conversion session. - Creating a "Geometry Definitions" collection to store shared geometry. - Adding instance definition proxies to the root collection. Addresses issues with duplicate geometry and improves stream performance. * Fixes geometry processing for instance handling Refactors geometry processing logic to handle instances more efficiently. It now correctly applies transformations for single objects, ensuring accurate placement in the scene. Simplifies processing of transforms where necessary for single objects. Removes redundant logging. * LFG!!! Matrix4x4 Transposed Adds an application ID to instance references. * Fixes RenderMaterials * Refactors dependency injection for settings * Reduces comment clutter in Navisworks converters Removes unnecessary comments to enhance code readability and maintainability. Simplifies the logic flow by eliminating obsolete comments that do not provide value, promoting a cleaner codebase moving forward. Relates to issue jonathon/cnx-2817-adopt-displayvalue-proxification-pattern-in-navisworks. * Renames methods for clarity and updates logic Refactors method names to improve readability and understanding of functionality. Consolidates selection logic related to representation modes and enhances the cohesiveness of the code. Also updates the property extraction method for better clarity on its purpose. Relates to the adoption of the display-value proxification pattern. * Refines COM object management and method naming Improves memory safety by ensuring all COM objects are explicitly released in try-finally blocks. * Refactors constants usage for geometry identification Introduces new constant definitions to standardise fragment ID prefixing. * Refactors Navisworks build process for resilience Adds error checking to ensure the Navisworks version is set before build occurs, and improves error handling to avoid empty output directories. Updates file copy logic to handle resource and ribbon files correctly. Ensures that the Navisworks plugin is correctly packaged and deployed. Addresses CNX-2788 * Improves geometry retrieval and checks Refactors geometry definition retrieval for better readability. * Refactors property name sanitisation logic Consolidates the logic for sanitising property names into a more concise format. * Refactors method signature for clarity * Update Converters/Navisworks/Speckle.Converters.NavisworksShared/Services/InstanceStoreManager.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Enhances fragment processing logic and error handling Improves null handling for selection paths to prevent crashes. * Changes fragment ID method visibility to public Updates the visibility of the fragment ID generation method to public, allowing it to be accessed from outside the class. * implementing more robust error handling during COM interop operations. * Updates method signatures to replace base geometry types with shared models, ensuring consistent handling of geometry data. * Refactors parameter list for clarity --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> Co-authored-by: Oğuzhan Koral <45078678+oguzhankoral@users.noreply.github.com>	2025-11-17 19:37:02 +03:00
