I use fusion. I will usually export as STEP, because that is usually the best quality. But I always inspect the model in Studio because occasionally when studio imports/converts it there are defects. The next two posts shows the kind of defects I am talking about.
If the STEP has defects and I have to export STL, I don’t use the export option to make an STL or 3mf like I do for the STEP, because the resolution is way too low. What I do is right click the component and click “Save as Mesh”. I find the ASCII mode makes a better quality STL than Binary. Also, I observe what settings are modified when choosing the high resolution from the drop down box and make a custom resolution a little better quality than high. The high setting isn’t good enough for me. Make sure you don’t make the quality too high or the file will be too big and the difference won’t be noticeable in a 3D print, and it will slow down studio.
If you export a component with sub-components as STEP, it will export as an assembly and use the sub-component names as the object names in studio
If you right click and use “Save as Mesh” for a component with sub-components as STL, it will export as an assembly and use the body names (not component) as the object names in studio. So in this case, if you want to have meaningful object names, you need to change the body names into something meaningful in fusion.
