I am new to Atom 3D (V22)... Every time I "Export" the finished part, it always comes up to export as ".stp" and then I have to scroll down to the bottom of the file types to select ".stl" It would nice if I could set this somehow to ".stl" as the default. Could this be done in settings? - I have search Settings and cannot find an option for this. If there is, please let me know. The other way to fix this is for the program to remember the last Export file type selected, and then use that each time as the default.
