Class IfcStoreCache
- Namespace
- GeometryHelper.IfcConvert.Core
- Assembly
- GeometryHelper.IfcConvert.dll
Thread-safe in-memory cache and high-level reader for opened IFC models. Encapsulates the xBIM engine and provides pure GeometryHelper geometry APIs. Exposes zero xBIM types in its public and member interface to allow seamless assembly resolution.

IfcStoreCache
- Implements
- Inherited Members
Constructors
- IfcStoreCache(string)
Initializes a new cache by opening the specified IFC file.
Properties
- Count
Gets the number of products indexed in this store.
- DefaultOptions
Gets or sets default conversion options for this cache instance.
- DuplicateGlobalIds
Gets the GlobalIds that more than one product in the file uses. GlobalIds must be unique in IFC; when they are not, only the first product with the id can be reached by GUID-based queries.
- FilePath
Gets the file path of the opened IFC model, if loaded from disk.
- IsGlobalCached
Gets or sets whether this cache instance is managed in the global static cache.
- IsInMemory
Gets whether the file was read whole into memory. xBIM keeps a large file in a database on disk instead (a 114 MB one, for one) and reads it as it is asked.
- OriginalLengthUnit
Gets the original length unit name reported by the IFC model (e.g. METRE, MILLIMETRE).
- ProductCount
Gets the number of products indexed in this store.
- SchemaVersion
Gets the schema version of the opened IFC store (e.g. IFC2X3, IFC4).
Methods
- ClearGlobalCache()
Clears all globally cached stores and disposes their underlying resources.
- ClearGlobalCache(string)
Clears and disposes a specific file from the global cache.
- Dispose()
Releases resources and closes the underlying store if not globally cached.
- EnumerateGeometries(IfcConvertOptions)
Lazily enumerates converted IfcProductGeometry instances across the model, minimizing memory usage for large files.
- EnumerateSolids(IfcConvertOptions)
Lazily enumerates converted GeoSolid3 bodies across the model.
- GetAllGeometries(IfcConvertOptions)
Converts every product across the model and returns them all at once: the ones EnumerateGeometries(IfcConvertOptions) gives, in the same order.
- GetAllSolids(IfcConvertOptions)
Converts and returns all GeoSolid3 bodies present in the entire IFC model, product by product in the order EnumerateSolids(IfcConvertOptions) gives them, and on every core at once as GetAllGeometries(IfcConvertOptions) converts them.
- GetGeometriesByType(string, IfcConvertOptions)
Retrieves complete IfcProductGeometry representations for products of a specific IFC type.
- GetGeometry(string, IfcConvertOptions)
Retrieves the complete IfcProductGeometry (including closed solids, open surfaces, and metadata) by GlobalId.
- GetGlobalCacheInfo()
Gets diagnostic information about all currently cached IFC stores.
- GetOrCreate(string)
Gets an existing cached store for the given file path, or creates and caches a new one.
- GetProductCatalog()
Retrieves a lightweight catalog of product metadata (GUID, Name, Type, Tag) without converting 3D geometry.
- GetProperties(string)
Retrieves all IFC property sets and quantity sets for a product by its GlobalId. Returns an empty dictionary if the product is not found or has no property sets.
- GetProperty(string, string, string)
Retrieves a single property value from a named property set. Returns null if the product, property set, or property is not found.
- GetSolid(string, IfcConvertOptions)
Retrieves a single GeoSolid3 by product GlobalId (GUID). If the product contains multiple solids, returns the largest body by volume. Returns null if not found or if the product has no closed solid representation.
- GetSolids(string, IfcConvertOptions)
Retrieves all GeoSolid3 bodies belonging to a product by its GlobalId (GUID). Returns an empty list if not found or if the product has no closed solid representation.
- GetSolidsByType(string, IfcConvertOptions)
Retrieves all GeoSolid3 bodies for products of a specific IFC type (e.g. "IfcWall", "IfcBeam", "Wall").
- Open(string, IfcConvertOptions)
Opens an IFC file and initializes a new IfcStoreCache.
