Hi,

While importing .PCB file from Altium, There are some changes (mentioned below) in pcb as shown in images.
The main file was in binary .PCB and I changed it to ASCII .PCB to import in EasyEDA. As described in https://docs.easyeda.com/en/Import/Import-Altium-Designer/index.html
1st images are of Altium and another are from EasyEDA.

1. Copper areas are vanished. I can't even do it by my self! I also had searched for this fault in forum but can't solve my issue. All Layers/components are visible.
2. There is change in top silk layer.
   1st and 2nd images illustrates these differences.
3. There is missing pad in antenna.
4. There is change in top solder layer. In 3rd image of Altium, top solder layer is highlighted.
   3rd and 4th images illustrates these differences.

Thanks for help in advance.
