Hi guys,
 
I need your help!!!
I downloaded a cad file (.DXF multi format) from internet. I use AutoCAD 2002 but when i open this file there is the message: "the file is currently in use or is read-only. Would you like to open the file read-only?" I press "yes" and then AutoCAD writes "improper the entry name LUCE.1 on line.86. Invalid or incomplete DXF input-drawing discarded." and it doesn't open!!!
I don't know what happens?
what is DXF multi format???
Can anyone help me??
 
Thanks!!!!
 

It is probably a file in a different file format (just the same extension). There is no "multi format" for AutoCAD DXF files.

Thanks for the reply Vladimir!!

 
Maybe you have right! This model i downloaded http://www.fallingpixel.com/3d-models/11061
i opened .3ds!
3ds is the same with .dxf? Is there any difference?
 
I'm not familiar with CAD!! I need this file to be exported to .sat, to open with CFD programs!! But when i export .3ds there is a message that says the items i selected are not solids!
 
Do you have any idea?
 
Thanks friend!!!

I see - the "multi format" refers to that the DXF format is usable in multiple appliactions. Both DXF and 3DS files are Autodesk formats and they should be readable in AutoCAD.

Thanks for the reply!!
 
I' ll try and other CAD programs!!
