If I 3D export the same project multiple times without changing anything at all, the STEP file randomly is missing different components. If I get very lucky all the components will get included, but more often than not several are missing. I've attached a screenshot of several attempts at exporting a good 3D STEP file, as you can see from the sizes they are all different, the smaller ones missing more components. I'm running the latest EasyEDA Pro, the **desktop** MacOS Apple Silicon version (2.0.30). My guess is that the 3D export times out and quits before it renders some components, perhaps a timeout value in the code needs to be made larger.
