This call can be used to save a model in XML Format, this XML serialization is advised for ifcXML files of schema IFC2x3 TC1 and before. The file name can be any unicode filename with a character length of 16 bits.


public const string IFCEngineDLL = @"IFCEngine.dll";

[DllImport(IFCEngineDLL, EntryPoint = "sdaiSaveModelAsXmlBNUnicode")]
public static extern void sdaiSaveModelAsXmlBNUnicode(Int32 model, byte[] fileName);    

Property model

Size: 32 bit / 4 byte (value)
Handle of the model containing the IFC file, this handle is needed in many other calls and given when the model is created.

Property fileName

Size: 32 bit / 4 byte (reference)
Address of string containing the path of the IFC file, for example 'C:\myPath\myFile.ifc' or 'C:\myPath\myFile.ifcXML'.


Here you can find code snippits that show how the API call sdaiSaveModelAsXmlBNUnicode can be used.

string ifcFileName = "myFile 友𠂇又.ifc";

//  The schema file is expected to be IFC2X3_TC1.exp as this XML format is typically used for IFC2x3 (TC1)
Int32 model = IfcEngine.x86.sdaiOpenModelBNUnicode(0, System.Text.Encoding.Unicode.GetBytes(ifcFileName), System.Text.Encoding.Unicode.GetBytes("IFC2X3_TC1.exp"));

if (model != 0)
    ...         //  Use the open model to read/write/edit the content
    ...         //  or to create geometry

    string ifcFileNameSaving = "mySavedFile 友𠂇又.ifc";            //  The file name is expected to end at .ifx or .ifcXML, this is of course totally free from technical Point-Of-View

    IfcEngine.x86.sdaiSaveModelAsXmlBNUnicode(model, System.Text.Encoding.Unicode.GetBytes(ifcFileNameSaving));

    model = 0;  //  Not required of course
