Abstract: A method of automatic logic application comprises receiving input from a user indicating a desire to create a shape, the shape made up of at least three points in an n-dimensional space, detecting the at least three points, and creating a vector set in the n-dimensional space for the at least three points. The method further includes comparing the vector set against a shape classifier of all available n-dimensional shapes to create a match score for each of the n-dimensional shapes, selecting an n-dimensional shape with the highest match score as a selected shape, and identifying a set of control points for the shape, based upon the selected shape. Given the control points and recognized shape, custom logic may be applied to the user-inputted shape.
