No I speak about help of Fusion 360 for UpLoad a ".sab" file format!
SAT/SMT Files (*.sab, *.sat, *.smb, *.smt)
It can, but alas seems the .sab file from DesignSpark is exotic or too old...
Failed!
I don't get this file: i just try to make the same fillet inside DesignSpark!
So seems it's now possible for obtain the file in Moi! :)
Sure a little tricky lines command!
