Hi lapaev, a step export will be really the exact same thing as the one for OBJ export, just instead of having a filename that ends with .obj have one that end with .stp .

The exporter will determine which file format to use based on what file extension is on the file name given to it.

So for example if you want to make a shortcut key that will write a STEP file of a fixed filename to c:\Users\Michael\Desktop\test.stp , you would put the following on a shortcut key:

SaveAs c:\Users\Michael\Desktop\test.stp


If you want to open that same fixed file with a shortcut key, put in:

Open c:\Users\Michael\Desktop\test.stp


If you want to import that file with a shortcut key (meaning add the file to the current existing model data rather than replacing it entirely like with Open), do this:

Import c:\Users\Michael\Desktop\test.stp


Hope this helps!
