SampleListIfcColumns

Overview

This programming manual in C# offers a practical demonstration of how to create an list of the columns in 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 header = new List<string>(); {
    header.Add("Name");
    header.Add("Profile");
    header.Add("Description");
    header.Add("Tag");
    header.Add("Width");
    header.Add("Height");
}
m_gridView.Rows.Clear();
m_gridView.Columns.Clear();
m_gridView.ColumnCount = header.Count;
for (int i = 0; i < m_gridView.ColumnCount; i++) {
    m_gridView.Columns[i].HeaderText = header[i];
}
var IfcColumns = BeaverHelper.kInstance.stp.Instnaces.FindInstances("IfcColumn", true);
foreach (STEPInstance IfcColumn in IfcColumns) {
    var rec = new List<string>(); {
        string Name = IfcColumn.Attributes.AttributeAsStr("Name").Value;
        string Description = IfcColumn.Attributes.AttributeAsStr("Description").Value;
        string Tag = IfcColumn.Attributes.AttributeAsStr("Tag").Value;
        string profile = ""; double Width = 0.0; double Height = 0.0;{
            STEPInstance IfcProductDefinitionShape = IfcColumn.Attributes.AttributeAsInst("representation").Value;
            if (IfcProductDefinitionShape != null) {
                STEPAttributeAggregate IfcShapeRepresentations = IfcProductDefinitionShape.Attributes.AttributeAsAggregate("representations");
