Three-dimensional generative design based on two-dimensional sketching

A non-transitory computer-readable medium storing program instructions that, when executed by a processor, cause the processor to generate a three-dimensional model from a two-dimensional sketch by performing the steps of:

• receiving input indicating a set of points defining a first sketch element and a second set of points defining a second sketch element included in a sketch;
• identifying one or more design relationships between the first sketch element and the second sketch element, wherein a first design relationship included in the one or more design designates at least one of the first sketch element and the second sketch element as a load-bearing sketch element;
• generating a computer model of the sketch that represents a structure linking the first sketch element and the second sketch element according to the one or more design relationships;
• and
• outputting the first sketch element, the second sketch element, and the structure for display.

A system, comprising:

• a memory storing a sketch application;
• and
• a processor that, upon executing the sketch application, is configured to:
• receive input indicating a set of points defining a first sketch element and a second set of points defining a second sketch element included in a sketch;
• identify one or more design relationships between the first sketch element and the second sketch element, wherein a first design relationship included in the one or more design designates at least one of the first sketch element and the second sketch element as a load-bearing sketch element;
• generate a computer model of the sketch that represents a structure linking the first sketch element and the second sketch element according to the one or more design relationships;
• and
• output the first sketch element, the second sketch element, and the structure for display.
