I have an Inv 2020 dwg that needs to be opened in 2018 and DWG Trueview is suppose to be albe to convert the file backwards. I run it through the converter, it says it has completed the operation successfully and a file is saved but when I try and open it in 2018 it just gives the "this file is from a newer version" complaint. Anyone know what is wrong or what I am doing wrong????
