i dunno where the original post has gone, where someone asked about batch stl export. He was having problems with the call

bpy.ops.export_mesh.stl(str)

----------------------


filepath is not a positional argument

you need to pass it like
bpy.ops.export_mesh.stl(filepath=str)

and if you want to export all selected object, each into a separate file, you gotta use different code...

e.g.

Code:

import bpy # Keep a copy of user selection sel_obs = bpy.context.selected_objects[:] for ob in sel_obs:         # Skip non-mesh objects     if ob.type != 'MESH':         continue     # Clear selection        bpy.ops.object.select_all(action="DESELECT")         # Select single object     ob.select = True         # Export single object to STL     bpy.ops.export_mesh.stl(filepath="D:\\temp\\batch_" + ob.name + ".stl")     # Restore user selection for ob in sel_obs:     ob.select = True bpy.context.scene.objects.active = ob
