Some time ago I used, at professional level, Autocad
there I can import an image as backgound, this give the ability to copy the image and to reproduce it in electronic format
in that case I imported city maps as to draw the corresponding dxf map that will be used to insert the electrical distribution lines (an add on was also able to control the consistency of the electric line drawed)
I would like to import in Eagle images (of PCB) to redraw it in a quick time to have full mod ability on it
often I find some image about a circuit that with little mod will be good for my use, but I must start to redrow the whole image to be able to modify only a little part of it
There is a function or an add on tool for this import of bachground ?
I've read to use the "import-bmp.ulp" but I'm a beginner and not able at all to find this function in Eagle 5.11
Many thanks for any answer
