When I export my PCB layout to an OBJ file from EasyEDA 6.4.19.4, the resultant mesh is not manifold. I need to convert it to a STEP file, but because it's non-manifold, it won't convert to STEP using any of the online conversion utilities. Any attempts to fix it in MeshMixer failed, flattening many of the features.
On a related note, any ideas when/if STEP export will be added?
Brand new interactions and interfaces. 
Easy to use and quick to get started.
