: Before AutoCAD 2015, object IDs in 64‑bit AutoCAD were represented by 64‑bit integers. If a 32‑bit VBA application accessed these values directly, it would cause a compilation error. To work around this, Autodesk introduced a ObjectID32 property that returned a 32‑bit version of the object ID. However, this property was removed in AutoCAD 2015 because VBA itself is now natively 64‑bit.
