Methods

InsertCopy(IModel, IEnumerable<IIfcProduct>, Boolean, Boolean, IProgress<Double>)

This is a higher level function which uses InsertCopy function alongside with the knowledge of IFC schema to copy over products with their types and other related information (classification, aggregation, documents, properties) and optionally geometry. It will also bring in spatial hierarchy relevant to selected products. However, resulting model is not guaranteed to be compliant with any Model View Definition unless you explicitly check the compliance. Context of a single product tend to consist from hundreds of objects which need to be identified and copied over so this operation might be potentially expensive. You should never call this function more than once between two models. It not only selects objects to be copied over but also excludes other objects from being coppied over so that it doesn't bring the entire model in a chain dependencies. This means that some objects are modified (like spatial relations) and won't get updated which would lead to an inconsistent copy.

Declaration

public void InsertCopy(IModel target, IEnumerable<IIfcProduct> products, bool includeGeometry, bool keepLabels, IProgress<double> progress = null)

Parameters

Type	Name	Description
IModel	target	The target model
System.Collections.Generic.IEnumerable<IIfcProduct>	products	Products from other model to be inserted into this model
System.Boolean	includeGeometry	If TRUE, geometry of the products will be copied over.
System.Boolean	keepLabels	If TRUE, entity labels from original model will be used. Always set this to FALSE if you are going to insert products from multiple source models or if you are going to insert products to a non-empty model
System.IProgress<System.Double>	progress	A progress delegate
