Finish the project before the trial runs out if possible. Don't use the key yet. Then when it's finished I believe you can export to dwg. Not perfect but probably much better than having to start all over. If you do have to redraw, tracing over dwg's is much easier.
Trial version won't let you export anything, no pdfs dwgs dxfs img... nothing
Screen shot is my only option, if SP can't convert the file.
On an even more sucky note, my key was supposed to be here yesterday. When it didn't show up I checked UPS tracking and said it "UPS has reported the package as damaged and will send back to shipper"
?????????????? So now I've got to call softplan when they open and see if they can over night me a key b/c I've GOT to get back to work on these plans for my Turkish Clients. Which by the way has been really fun working with them. Their tastes are nothing like what typical american house plans look like.
