Ok, my total time in RD is about 1 hour so far so please excuse what is probably a basic question.

I'm doing my best to convert raster lines to ACAD lines but it's not working as easily as it did with the sample images. I guess I need to convert my image to a bitonal image but I can't find how to do that. Right now the image has white, black, and red (and probably millions of variations of each since it's a regular scanned image).

Can someone point me in the right direction or tell me if I'm even on the right path?

Thanks
