International Classification:

G09G 5/00
G06T 17/00

US Classification:

345619, 345420

Abstract:

Embodiments of the invention comprise methods and systems for modifying the geometry data of a CAD object through modification of an arbitrary cross section, the CAD object being stored within a computer aided design modeling system. The method includes receiving, from a user the position and orientation of a cross section plane, the cross section plane being arbitrarily positioned relative to the orientation of a CAD object, and wherein the arbitrarily positioned and oriented plane is intersecting the CAD object. The CAD system generates a user modifiable two dimensional cross section from the intersection of the cross section plane and the CAD object, the cross section having a plurality user modifiable control elements. Changes to the control elements are correspondingly made to the cross section plane and the CAD object.

US Classification:

345420, 345419, 703 1, 715964

Abstract:

Systems and methods for creating and editing D solids and surfaces in an intuitive manner are described. A single tool infers the most-likely correct action based on its context to a particular geometry case. The tool predicts a user's intended modification, and performs the predicted modification without recording related history information. The method includes receiving a selection of at least one CAD object. The method also includes the tool automatically predicting the user's intended type of modification to the at least one CAD object based on the type of the at least one CAD object and the at least one CAD object's relationships with the geometry of at least one surrounding (or related) CAD object. The tool can perform multiple types of modifications, and the modification is selected from the multiple types of modifications, without explicit commands from the user directing the type of modification.

Abstract:

Systems and methods for creating and editing 3D solids and surfaces in an intuitive manner are described. A single tool infers the most-likely correct action based on its context to a particular geometry case. The single modification tool predicts a user's intended modification, and performs the predicted modification without recording related history information. The method includes receiving a selection of the at least one CAD object.

Inventors:

Frank DeSimone - Carlisle MA, US
Daniel Dean - Acton MA, US
Dima Feinhaus - Newton MA, US

Assignee:

SpaceClaim Corporation, Inc. - Concord MA

International Classification:

G06T 17/00

US Classification:

345420, 345419, 345424, 345441, 345442, 700182, 703 2, 706919, 715964

Abstract:

A three-dimensional object modeling tool is described that can derive the 2D cross sections of one or more lofted or unlofted surfaces, allowing those surfaces to be modified instantly. The modeling tool (loft tool) includes sub-tools for selecting a surface, moving a 2D section, editing a 2D section, creating a 2D section, and removing a 2D section. By analysis of the selected lofted surface and its faces, the loft tool can derive an appropriate number of 2D cross section to present to the user for manipulation. When deriving the 2D cross section the modeling tool operates by simplifying the curves making up the lofted surface, and from these can generate 2D cross section that can be easily manipulated and used to instantly update the lofted surface and redisplay it for further user modification.

Assignee:

SpaceClaim Corporation - Concord MA

International Classification:

G06G 7/48

US Classification:

703 7, 700 98

Abstract:

A three-dimensional solid geometry modeling method is described that can move or modify any piece of solid or surface geometry, such as a protrusion or depression, when faces are changed in a way that is not obvious or predictable from the original data. The method involves a combination of local changes and a context-based process that uses simplification, detaching, modification, and reattaching algorithms. The method is invoked automatically when a modeling tool (such as Move or Pull) is used to move or modify a piece of geometry. During the movement or modification, the geometry reflects the changes dynamically as the user interacts with the modeling tool. When performing the modification, simplification of the faces and edges can be manually or automatically invoked.
