In computer assisted design, a sheet body is patched to a target body, wherein the boundary edges of sheet body are partially coincident with the target body. All segments of the sheet body boundary that are coincident or non-coincident to the target body are detected; for a non-coincident segment with at least one end point which is in the interior of the target body but not on the sharp edge, the corresponding patch position on the target body is determined, and the segment or an extension is projected on the target body; for a non-coincident segment with both end points on sharp edges of the target body, the open region between the segment and the sharp edges is filled as extension of the faces of sharp edges; the coincident segments and the projected or extended non-coincident segments are combined to divide the target body into separate regions; and one of the regions is replaced by the sheet body.
