Facilitated editing of generative design geometry in computer aided design user interface

A system comprising:

• a non-transitory storage medium having instructions of a computer aided design program stored thereon;
• and
• one or more data processing apparatus communicatively coupled with the non-transitory storage medium to run the instructions of the computer aided design program, the one or more data processing apparatus being configured by the instructions of the computer aided design program to:
• receive one or more editable smooth surfaces, wherein each of the one or more editable smooth surfaces has been constructed from at least a portion of a polygon mesh that has been obtained using a generative design process employing one or more input solids as one or more sub-spaces of an optimization domain of the generative design process, the one or more input solids being in a boundary representation format;
• render a visualization of the one or more editable smooth surfaces and the one or more input solids to a display device presenting a user interface of the computer aided design program;
• associate an operation sequence with the one or more editable smooth surfaces and the one or more input solids, wherein the operation sequence (i) converts the one or more editable smooth surfaces into the boundary representation format and (ii) combines the one or more boundary representation formatted smooth surfaces with the one or more input solids to produce a watertight three dimensional model of an object;
• modify the one or more editable smooth surfaces in response to user input received through an input device associated with the user interface of the computer aided design program, while preventing disconnection of the one or more editable smooth surfaces from the one or more input solids, to produce one or more modified editable smooth surfaces;
• update the visualization presented in the user interface on the display device responsive to production of the one or more modified editable smooth surfaces;
• and perform the operation sequence to convert and combine the one or more modified editable smooth surfaces with the one or more input solids to produce the watertight three dimensional model of the object.

A non-transitory computer-readable medium encoding a computer aided design program operable to cause one or more data processing apparatus to perform operations comprising:

• receiving, by the computer aided design program, one or more editable smooth surfaces, wherein each of the one or more editable smooth surfaces has been constructed from at least a portion of a polygon mesh that has been obtained using a generative design process employing one or more input solids as one or more sub-spaces of an optimization domain of the generative design process, the one or more input solids being in a boundary representation format;
• rendering, by the computer aided design program, a visualization of the one or more editable smooth surfaces and the one or more input solids to a display device presenting a user interface of the computer aided design program;
• associating, by the computer aided design program, an operation sequence with the one or more editable smooth surfaces and the one or more input solids, wherein the operation sequence (i) converts the one or more editable smooth surfaces into the boundary representation format and (ii) combines the one or more boundary representation formatted smooth surfaces with the one or more input solids to produce a watertight three dimensional model of an object;
• modifying, by the computer aided design program, the one or more editable smooth surfaces in response to user input received through an input device associated with the user interface of the computer aided design program, while preventing disconnection of the one or more editable smooth surfaces from the one or more input solids, to produce one or more modified editable smooth surfaces;
• updating, by the computer aided design program, the visualization presented in the user interface on the display device responsive to the modifying;
• and
• performing, by the computer aided design program, the operation sequence to convert and combine the one or more modified editable smooth surfaces with the one or more input solids to produce the watertight three dimensional model of the object.
