1. A computer-implemented method comprising:

  • receiving a selection of a two-dimensional (2D) representation of an object;

    receiving input selecting a location of a sweep path origin relative to a bounding box for the 2D representation of the object, the location of the sweep path origin selected from an edge or corner of the bounding box;

    obtaining one or more inputs each setting a value for a respective one of a set of two or more extrusion parameters, the set of two or more extrusion parameters not defining the 2D representation of the object and including a twist parameter, scale parameter, or bend parameter;

    generating, based on the extrusion parameters and from the selected location of the sweep path origin, a sweep path for extruding the 2D representation of the object, the sweep path being a non-planar space curve originating from the sweep path origin; and

    performing a translational sweep of the 2D representation of the object along the sweep path to generate a three-dimensional (3D) extrusion from the 2D representation of the object.
