PTC has been granted a patent for a parametric feature-based 3D CAD system that enables multiple users to simultaneously edit a 3D model without restrictions. Users can edit the model in different representations, with changes applied across all views. The method involves displaying the model as a visual model, feature list, and textual representation, allowing for seamless editing.

A recently granted patent (Publication Number: US11893312B2) outlines a method and system for executing three-dimensional (3D) computer-aided design (CAD). The method involves displaying a user interface on a client device that allows for editing a 3D CAD design. Within this interface, the design is displayed simultaneously as a visual model, a feature list, and a textual representation of a corresponding program. Users can interact with the visual model, feature list, and textual representation, with corresponding portions highlighted based on user interactions. Any edits made by the user are applied and displayed across all three representations.

Furthermore, the patent describes maintaining a syntax tree of an object-oriented representation of the program and each entry in the feature list as subtrees of the syntax tree. Additionally, the method involves communication with a server that stores multiple files of the 3D CAD design grouped into a compound document. These files include data representations of CAD data like assemblies and parts, as well as separate non-CAD data files distinct from CAD data files. The system described in the patent is configured to perform the method, displaying the 3D CAD design in various representations and allowing for interactive editing while ensuring consistency across the visual model, feature list, and textual representation.
