Abstract:
1. A computer-implemented method of generating a display representation of a computer-aided design (CAD) drawing stored on a computing device, comprising: loading the computer-aided design (CAD) drawing into a system memory of the computing device; identifying one or more layers of the CAD drawing to include in the display representation, wherein each of the one or more layers is associated with a set of drawing elements and a set of layer display properties specifying a first drawing style to use for the set of drawing elements associated with a respective layer; identifying a viewport display property for a first layer of the one or more layers, wherein the viewport display property specifies a second drawing style to use for the set of drawing elements associated with the first layer; overriding the first drawing style specified in the set of layer display properties with the second drawing style specified by the viewport display property; generating the display representation, wherein the display representation includes the drawing elements associated with the one or more layers, and the appearance of the drawing elements associated with the first layer is based on the viewport display property; and
