Wrapping a two-dimensional (2d) sketch onto a three-dimensional (3d) model

A computer system comprising:

• a computer processor;
• and
• computer-based memory operatively coupled to the computer processor, wherein the computer-based memory stores computer-readable instructions that, when executed by the computer processor, cause the computer-based system to wrap a two-dimensional (2D) sketch onto a three-dimensional (3D) model with a process comprising:
• placing the 2D sketch onto a 2D grid;
• transforming the 2D grid to an initial location relative to the 3D model;
• mapping the 2D grid onto the 3D model to produce a 3D grid wrapped around the 3D model;
• evaluating the 2D sketch onto the 3D grid to produce a 3D image wrapped around the 3D model, wherein the 3D image wrapped around the 3D model corresponds to the 2D sketch;
• and
• creating one or more curves on the 3D model by projecting the 3D image onto the 3D model.
