Question: can autocad 2018 open 2019 files?
Answer: YES, Vanilla AutoCAD 2019 CAN be saved backwards. Traditionally, since AutoCAD version 2000, Autodesk changes its DWG file format after three versions. ... Essentially, this means if you save a drawing file in 2019 or 2018, it will be a different drawing format than anything saved with 2017 or earlier products.
