GetPropertyByNameW
When the property does not exist yet and the name is unique
the property will be created on-the-fly and the handle will be returned.
When the name is not unique and given to a class or instance 0 will be returned.
Syntax
public const string EngineDLL = @"engine.dll";[DllImport(EngineDLL, EntryPoint = "GetPropertyByNameW")] public static extern Int64 GetPropertyByNameW(Int64 model, string name); [DllImport(EngineDLL, EntryPoint = "GetPropertyByNameW")] public static extern Int64 GetPropertyByNameW(Int64 model, byte[] name);
Property model
Size: 64 bit / 8 byte (value)Property name
Size: 64 bit / 8 byte (reference)

Here you can find code snippits that show how the API call GetPropertyByNameW can be used.
using Engine; static void Main(string[] args) { Int64 model = Engine.x86_64.CreateModel(); if (model != 0) { // // Classes // Int64 classArc3D = Engine.x86_64.GetClassByNameW(model, System.Text.Encoding.Unicode.GetBytes("Arc3D")); // // Datatype Properties (attributes) // Int64 propertyRadius = Engine.x86_64.GetPropertyByNameW(model, System.Text.Encoding.Unicode.GetBytes("radius")), propertyStart = Engine.x86_64.GetPropertyByNameW(model, System.Text.Encoding.Unicode.GetBytes("start")), propertySize = Engine.x86_64.GetPropertyByNameW(model, System.Text.Encoding.Unicode.GetBytes("size")), propertySegmentationParts = Engine.x86_64.GetPropertyByNameW(model, System.Text.Encoding.Unicode.GetBytes("segmentationParts")); // // Instances (creating) // Int64 myInstanceArc3D = Engine.x86_64.CreateInstanceW(classArc3D, (string) null); double Pi = 2.0 * Math.Acos(0.0), radius = 2.1, start = 0.0, size = 2.0 * Pi; Int64 segmentationParts = 36; Engine.x86_64.SetDatatypeProperty(myInstanceArc3D, propertyRadius, ref radius, 1); Engine.x86_64.SetDatatypeProperty(myInstanceArc3D, propertyStart, ref start, 1); // in this case we could also do without, i.e. default value Engine.x86_64.SetDatatypeProperty(myInstanceArc3D, propertySize, ref size, 1); // in this case we could also do without, i.e. default value Engine.x86_64.SetDatatypeProperty(myInstanceArc3D, propertySegmentationParts, ref segmentationParts, 1); // // The resulting model can be viewed in 3D-Editor.exe // Engine.x86_64.SaveModelW(model, System.Text.Encoding.Unicode.GetBytes("c:\\created\\myFile.bin")); Engine.x86_64.CloseModel(model); } }
