Note to the LCAD devs: It might be a good thing to look into the gschem image import code. It looks like I can continue to use LCAD for drawings not needing an image import, while continuing to use gschem for drawings I need to import an image for. That is why I wanted to use LCAD for this process. To that end, I wanted to use the PCB image output for the base LCAD drawing in order to keep the accuracy and not re-draw the image.Īfter posting my message, I ended up importing my image into the gEDA gschem schematic capture program, which has limited mechanical drawing capabilities. The whole idea of CAD/EDA is to make the processes easier and less error-prone. To maintain two scales of the same object in PCB is not acceptable.

I cannot scale the original PCB drawing, since it is obvious it must be the size of the circuit board in the real world. It looked very coarse, but still the large size. I did try reducing the PCB PPI option, with the results you warn about. As I said, I even tried importing the PNG file into Inkscape and converting to a DXF file, as the LCAD manual suggests, with the fatal crash results in LCAD when I tried to import it. I had tried several adjustments to the PCB PNG output parameters, such as changing the Pixels Per inch (PPI) option, with virtually the same results in LCAD. It was generated from the gEDA PCB printed circuit board editor as a PNG file. Alas, I don't think I can change the scale of the original image.
