Abstract: Highlights•Perhaps the first network for completing query sketches of CAD models.•A novel two-stage generator architecture has been proposed.•The discriminator only utilizes a patch around the missing portion.•A novel training strategy involving two-cascaded generators with two local discriminators.•Demonstrated the novel architecture’s superior performance over existing works.
