This Archtectural Drawing is AutoCAD 2d drawing of Traditional sofa set cad blocks in AutoCAD, dwg file. Traditional style sofas are usually wide-set, even if you opt for a two-seater couch. The backs are either camel-like or curved, but either way, you should expect that the sofa has a low height. There are also high-back traditional sofas, but this is not as common in regular households.
