Many years the developers of EasyEda could not implement such thing as "Export PCB to STEP file.
Many programs such as DeepTrace, KiCAD have such standard option. I even don't want to talk about Altium Designer.
Instead of make such option they propose us to straggle with Fusion or export project files to Altium Designer.
But even export to Altium Designer is totally broken.
The only things you can find are Chinese promises...
