1. A method for modifying a computer-aided design model of a three-dimensional object implemented by a computer, the method comprising:
- providing a threshold wall width ranging from about 150% of a road width of build material deposited from a layered deposition system to about 200% of the road width;
providing at least one sliced layer polyline of the computer-aided design model to the computer, the at least one sliced layer polyline comprising a first portion and a second portion;
determining, by the computer, a first distance between the first portion and the second portion; and
adjusting, by the computer, locations of the first portion and the second portion to provide a second distance between the first portion and the second portion if the first distance is less than the threshold wall width, wherein the second distance is about equal to the threshold wall width, or greater.

Abstract
A method for modifying a computer-aided design model of a three-dimensional object, the method comprising establishing a threshold wall width, providing at least one sliced layer polyline of the computer-aided design model, determining a first distance between first and second portions of the at least one sliced layer polyline, and adjusting locations of the first and second portion to provide a second distance if the first distance is less than the threshold wall width, where the second distance is about equal to the threshold wall width, or greater.

14. A method for modifying a computer-aided design model of a three-dimensional object implemented by a computer, the method comprising:
-
providing a threshold wall width; providing at least one sliced layer polyline of the computer-aided design model to the computer, the at least one sliced layer polyline comprising; a first vertex interconnecting a first segment and a second segment; and a second vertex interconnecting a third segment and a fourth segment; determining, by the computer, a first minimum distance between the first vertex and the first and second segments; determining, by the computer, a second minimum distance between the second vertex and the third and fourth segments; adjusting, by the computer, a location of the first vertex if the first minimum distance is less than the threshold wall width; and adjusting, by the computer, a location of the second vertex if the second minimum distance is less than the threshold wall width, wherein an adjusted distance between the adjusted first vertex and the adjusted second vertex is about equal to the threshold wall width, or greater. - View Dependent Claims (15, 16, 17, 18, 19, 20)
