Methods for updating knitting instructions based on physical measurement of knitted article

A computer-implemented method for updating knitting instructions, the method comprising:

• defining one or more virtual reference indicators on a surface of a three-dimensional (3D) model of an article to be knitted by a computer-controlled flatbed knitting machine, wherein the 3D model is defined in a 3D space represented in an application running on a computer system and is displayed on a display of the computer system within a user interface of the application, and wherein the one or more virtual reference indicators define one or more regions;
• generating knitting instructions for the computer-controlled flatbed knitting machine, wherein the knitting instructions specify that the one or more virtual reference indicators defined on the surface of the 3D model are to be knitted as one or more physical reference indicators that form part of the knitted article;
• knitting the knitted article using the knitting instructions;
• and
• updating the knitting instructions by adjusting at least one of a number of courses or a number of wales within the one or more regions of the 3D model by dividing the at least one of the number of courses or the number of wales by a compensation factor that accounts for differences between a physical measurement that specifies a first distance along a first path along the knitted article, the first path being defined by the one or more physical reference indicators that form part of the knitted article, and an intended dimension of said first distance,
• wherein the updating of the knitting instructions by the adjusting of the at least one of the number of courses or the number of wales within the one or more regions of the 3D model comprises using a ratio between the physical measurement and a virtual measurement corresponding to the physical measurement as the compensation factor, wherein the virtual measurement specifies a second distance along a second path on the surface of the 3D model, the second path being defined by the one or more virtual reference indicators.
