**With the `AddObjectHelper` class** [![enter image description here][1]][1] Further to @brockmann's answer The `AddObjectHelper` class sets up some of the usual suspects for us, including location, rotation and align. It appears you have used the _`text editor > templates > python > Addon add object`_ template, so let's stick with it in. class OBJECT_OT_add_cylinder(Operator, AddObjectHelper): """Create a new Mesh Object""" bl_idname = "object.add_cylinder" bl_label = "Add Mesh Object" bl_options = {'REGISTER', 'UNDO'} # set other args like name and description for all vertices : IntProperty( name="Vertices", description="Number of Vertices", min=0, default=32) radius : IntProperty(default=2) depth : FloatProperty(default=2) def execute(self, context): bpy.ops.mesh.primitive_cylinder_add( vertices=self.vertices, radius=self.radius, depth=self.depth, # those defined in AddObjectHelper align=self.align, location=self.location, rotation=self.rotation) return {'FINISHED'} _Note: I've adjusted the classname `OBJECT_OT_add_cylinder`and `bl_idname = "object.add_cylinder"` to match desired naming convention_ One issue tho is that its draw method puts its stuff first, so may need to add your own draw method to re-sort as desired def draw(self, context): layout = self.layout layout.prop(self, "vertices") layout.prop(self, "radius") # and so on Other examples based on add object template https://blender.stackexchange.com/a/133880/15543 https://blender.stackexchange.com/a/102239/15543 [1]: https://i.sstatic.net/rI35i.png
