In some implementations, a method of sketch-based placement of computer-generated graphical objects is performed at a device including one or more cameras and non-transitory memory coupled to one or more processors. The method includes obtaining an input directed to a content creation interface (e.g., a sketchpad), wherein the input corresponds to a sketch of a candidate object, and wherein the content creation interface facilitates creation of computer-generated graphical objects presentable using the device. The method also includes: obtaining a three-dimensional (3D) model using the input that corresponds to the sketch of the candidate object; generating a computer-generated graphical object using the obtained 3D model; and causing presentation of the computer-generated graphical object together with imagery obtained using the one or more cameras of the device.
