NURMS are used in commercial 3D packages such as Autodesk 3ds Max to perform mesh smoothing operations. The mesh smooth modifier in 3ds Max operates by applying this algorithm to a low-polygon mesh and creates a high-polygon smoothed mesh.

A man using AutoCAD 2.6 to digitize a drawing of a school building. AutoCAD was derived from a program that began in 1977, and then released in 1979 [5] named Interact CAD, [6] [7] [8] also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle.
These provide an approach to the drawing process where scale and placement on the drawing sheet can easily be adjusted in the final draft as required, unlike in hand drafting. 3D CAD 3D wireframe is an extension of 2D drafting into a three-dimensional space .
Non-uniform rational basis spline (NURBS) is a mathematical model using basis splines (B-splines) that is commonly used in computer graphics for representing curves and surfaces. It offers great flexibility and precision for handling both analytic (defined by common mathematical formulae ) and modeled shapes .
AutoCAD opens documents with DWG compatibility as a "DWG file format version code" where the specific version code can be found by opening the .dwg file in Windows Notepad or any text editor program. The file contents starts with this string. The file format version code (tag) is dependent on the AutoCAD version. [2]
A large group of textual and video tutorials exists for beginners to design their own PCBs. [22] The DIY electronics site SparkFun uses EAGLE and releases the EAGLE files for boards designed in-house. SparkFun Electronics [23] is a company that has grown due to the hobbyist market exemplified by Make magazine and others.
Between the mid-1940s and 1950s, various developments were made in computer software.Some of these developments include servo-motors controlled by generated pulse (1949), a digital computer with built-in operations to automatically coordinate transforms to compute radar related vectors (1951), and the graphic mathematical process of forming a shape with a digital machine tool (1952).
