Hi, I am encountering a new problem viewing 3D .STEP models in the EasyEDA Pro 3D viewer. I had no problem rendering my pcb boards in 3D last week. Now all 3D models in my personal library only show as gray boxes. When I import a new 3D Model from my PC, the log will report it as a successful upload, but when viewed via my browser from the EasyEDA Pro bottom-panel library (filter: personal, tab: 3d model) the newly uploaded 3d model .STEP file (as can be seen by its listed upload date) shows in the lower-right corner 'place' region as a gray box. I'm assuming this problem is affecting a large number of users ? Hopefully this will be resolved soon. If others are also experiencing this issue, please add your comments to the forum also. Thanks for your prompt attention to this matter.
