The edge blending operation makes the transition between two or more adjoining surfaces belonging to one solid body. Rotation operation creates solids by the rotational sweeping of the shape-defining element – the rotation contour about an axis in space. The classical assembly structure defined in the BUILD system, perhaps even earlier, has a structure consisting of an assembly, containing a list of instances each referring to a single object or an assembly.Įxtrusion operation creates solids by sweeping the shape-defining element – the extrusion contour. Most products consist of a set of linked objects organised in a structure called, at least sometimes, an ‘‘assembly’’. This means that the geometry is handled via a functional interface consisting of some general geometry handling functions. Geometry is handled in terms of the general entities: point, curve, surface, and it is up to the geometric package to sort out the geometric types. But in 3D, the correct use of coordinates can substantially accelerate our work.Īs a general strategy in modelling, the topology and geometry are handled separately. And most of the time, we do not even use coordinates, just the top-twenty CAD commands, the Ortho tool, and so on. In 2D, we only care for the X- and Y-axes but never used the Z-axis. First, the shapes and dimensions, later grids, and rulers.ģD is all about the third Z coordinate. Learn about product design using CAD, cost estimation and considerations in CAD design, and environmental considerations in product design.Ī CAD Designer must be introduced to some of the basic elements used in two-dimensional shape definition to work in CAD software. Module 04: Basics for CAD Design – Part 2.Study the terms and laws of solid mechanics, fluid mechanics and engineering mechanics. Module 03: Basics for CAD Design – Part 1.They will work with architects and design engineers to understand the requirements of their initial designs and turn them into accurate and detailed technical drawings in 2D and 3D models. Module 02: CAD Designer Career in the United KingdomĪ CAD Designer or Technician uses CAD software to create technical drawings and plans for products and parts used in the engineering, construction, and manufacturing industries.What is a Computer-Aided Design? Learn about the history of CAD, the importance and impacts of CAD, and the most used CAD software.
