I used Inkscape to modify the original 7 segments display on the left (10 pins) to build a SA08-11 7 segments display with 16 pins (really it is only 13).
I followed a tutorial and when I finished and try to put the new part in the breadboard I get a solid color rectangle instead of something similar to the original 7 segments by Fritzing.
The easiest thing is for you to upload the fzpz file of your part (7th icon from the left on the reply menu). We can then look at all the files and tell you whats wrong with it. Sounds like you don’t have copper0 and copper1 layers (at least not correctly).
The PCB svg has to have special groups.
A “silkscreen” group for all lines and text.
A “copper1” group with a “copper0” group inside it with all the contact pads.
