I am new to microstation and I am having trouble converting a microstation v8 drawing into a microstation v7 drawing. It started as an AutoCad drawing and I imported it into Version 8. Then I found where I could do a "save as" to save it as a version 7 drawing. Everytime I do, I get an error and then it creates the file, but it is empty and the file size is 0kb. Can someone please helpl me.
