DXF2DWG.LSP This lisp program will convert more than 1 .DXF file to .DWG files without user intervention. All you do is enter the file spec to convert (wild cards are allowed) & it creates a script file from the directory listing it created. It goes through the list of .DXF files to make sure they exist & their .DWG couterparts don't exist. The last command in the LISP program executes the script. The only problem that I've run into is that I can't delete the script file once it is done, because the file is still open. It puts this temporary script file in the directory pointed to by your system TEMP variable. DWG2DXF.LSP Does the reverse of the DXF2DWG program. You may run into a problem if you have a bad drawing that needs auditting. MAPLAY.LSP This lisp program converts Major_Minor Attribute layer names to more suitable names. It uses the file LAYER.MAP which you should put in your SUPPORT directory under ACAD directory tree. Actually it looks in each directory pointed to by the ACAD environmental variable until it finds it or exhausts the list. You can edit & change the LAYER.MAP file all you want. I've just given you a basic file to start with. The format of the file is quite simple. There are 6 fields, each seperated by a comma. The last field, which is the description & is not really needed can have commas within it. The fields are as follows using the following example line from file: 20_0,6,CONTINUOUS,0,photorev_20_0,Photorevised feature 20_0 Field 1. Original Major_Minor Attribute layer name 6 Field 2. New color number to use CONTINUOUS Field 3. Line type to set for that layer 0 Field 4. Width of line work on that layer (not yet implemented) photorev_20_0 Field 5. New Layer name to use Photorevised... Field 6. Full description or comment field I may use this LAYER.MAP file in the future to map the layers directly into the .DXF file, which is why field 4 is there.
