CAD Data Extraction and Automated Engineering Reports

CAD files contain a wealth of data: quantities, weights, lengths, attributes and properties. Automated extraction turns that data into reports in seconds.

What data can be extracted?

SourceData
2D DWGBlock counts and attributes, polyline lengths, areas, layer contents, text
3D modelsMass, volume, surface area, centre of gravity, bounding box
AssembliesComponent counts, structure, bought-out items
PropertiesPart numbers, materials, suppliers, revisions, authors
FeaturesHole counts and sizes, bends, welds, threads
BIM (Revit)Element quantities, parameters, room data, schedules
ElectricalWire lists, terminal plans, cable lengths, component lists

Engineering reports you can automate

  • Weight and centre-of-gravity reports for lifting and transport.
  • Material take-off for estimation and purchasing.
  • Surface area reports for painting and coating.
  • Welding length reports for costing and planning.
  • Equipment and instrument lists from P&ID or layout drawings.
  • Drawing registers with number, title, revision and status.
  • Project progress dashboards from PDM data.

Example: extracting block attributes in AutoCAD (.NET)

foreach (ObjectId id in modelSpace)
{
    if (tr.GetObject(id, OpenMode.ForRead) is BlockReference br)
    {
        foreach (ObjectId attId in br.AttributeCollection)
        {
            var att = (AttributeReference)tr.GetObject(attId, OpenMode.ForRead);
            rows.Add(new[] { br.Name, att.Tag, att.TextString });
        }
    }
}
// rows are then written to Excel with a reporting library

Output formats

  • Excel with company formatting, formulas and charts.
  • PDF reports with logos and signatures for customers.
  • CSV / JSON for ERP, BI tools or databases.
  • Web dashboards for managers and project teams.

Extraction at scale

For projects with thousands of drawings, extraction runs as a batch job, and results are stored in a database so reports can be refreshed at any time without reopening CAD files.

If someone is copying numbers from CAD into Excel, that process should be automated.
