Hi everyone, I work with Architectural Desktop 2005 and sometimes I need to convert drawings to 2000 format. I prefer using the Export to AutoCAD 2000 command. I wrote the following script to automate the process and it works well, but it adds the prefix ACAD- to all the converted drawings: filedia 0 aecexporttoautocad2000 filedia 1 The reason it has to add the prefix is because Windows would not allow it to overwrite a file while it's open, so it has to rename the file. I thought if I could save it to another folder I wouldn't have to rename it. So I added a line as follows: filedia 0 aecexporttoautocad2000 (strcat "c:/temp/" (getvar "dwgname")) filedia 1 But its not working. I'm guessing that the strcat can't be used in this situation. Can anyone tell me how this should be written so I can save the file to a different folder? Thanks, Juan
