Abstract:

According to one embodiment of the invention, a method for interfacing with a surface within a computer-aided drawing environment includes determining that a plurality of curves operable to define the surface constitute a P×1 surface condition. A P×1 surface condition is defined by a number of first curves equal to P and only one second curve. P is an integer greater than zero. The method also includes converting the P×1 surface condition into an N×M surface condition in response to determining that a plurality of curves constitute a P×1 surface condition. An N×M surface condition is defined by a number of third curves equal to N and a number of fourth curves equal to M. N and M are integers greater than one. The method also includes constructing an N×M surface under the N×M surface condition. The method also includes modifying the N×M surface to edit a drawing.

International Classification:

G06T 17/40

US Classification:

345420

Abstract:

A system, method, and computer program for selecting modification features on a solid model that is manipulated in a computer having software instructions, comprising: a computer system, wherein the computer system includes a memory, a processor, a user input device, and a display device; a computer generated geometric model stored in the memory in the memory of the computer system; and wherein the computer system selects a modification feature directly on a solid model using a computer peripheral input that communicates a modification intent from a user; suggests a plurality of additional selection features to include with the modification feature; verifies that the included plurality of additional selection features conforms to the modification intent by a visual highlighting; modifies the solid model according to the modification intent that results in a modified solid model and modified visual display information; and displays the modified solid model using the modified visual display information to the user; and appropriate means and computer-readable instructions.

Feng Yu - Irvine CA, US

International Classification:

G06F 17/50

Abstract:

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.
