SampleCreateIfcSite

Overview

This programming manual in C# offers a practical demonstration of how to create an instance of the IfcSite class within a model.

Sample code

For example:

var app = new Beaver.BcadApplication();
var doc = app.ActiveDocument;
if (doc == null)
    doc = app.Documents.Add();
var stp = doc.STEPDocument;
var IfcProject  = stp.Instnaces.FindInstance(-1);
var IfcSite = stp.Instnaces.CreateInstance("IfcSite"); {
	IfcSite.Attributes.AttributeAsInst("Ownerhistory").Value  = stp.Instnaces.FindInstance(-1);
	IfcSite.Attributes.AttributeAsStr("Description").Value = "description";
	IfcSite.Attributes.AttributeAsStr("Name").Value = "New Site";
	IfcSite.Attributes.AttributeAsStr("LongName").Value = "";
	IfcSite.Attributes.AttributeAsEnum("CompositionType").SetValue(Config.kInstance.CompositionType.SelectedValue);
}
{
	STEPInstance IfcRelAggregates = null; {
		var insts =  FindInstances("IfcRelAggregates", true);
		foreach (var inst in insts) {
			if (inst.Attributes.AttributeAsInst("RelatingObject").Value == IfcProject) {
				IfcRelAggregates = inst;
				break;
			}
		}
	}
	if (IfcRelAggregates == null) {
		IfcRelAggregates = stp.Instnaces.CreateInstance("IfcRelAggregates");
		IfcRelAggregates.Attributes.AttributeAsInst("RelatingObject").Value = IfcProject;
	}
	var RelatedObjects = new List<STEPInstance>(); {
		var objs = IfcRelAggregates.Attributes.AttributeAsAggregate("RelatedObjects").values;
		if (objs!= null) {
			foreach (STEPInstance obj in objs)
				RelatedObjects.Add(obj);
		}
		RelatedObjects.Add(IfcSite);
	}
	IfcRelAggregates.Attributes.AttributeAsAggregate("RelatedObjects").values = RelatedObjects.ToArray();
}
