Hello I don't understand ! I'm novice with autocad. I'm using Autocad 14 and I have a 3D construction drawing file. When I play "File", "Open", in the "Select File" window I choose my drawing file and I can see it in the small preview frame. But when I Open the file, the drawing frame is empty. I try Zoom, scrollbar ... and all layers are "on" My drawing don't appear ! Why ? Do anyone have an idea ? Help me please ! Thanks a lot claire
