The complete process of CAD designing and 3D modeling

Design and engineering are two words that orbit the modern world of creation in Melbourne. These are the pillars that have strengthened themselves with the use of Computer-aided designing and 3D modeling technology. The manufacturing and automotive scanning companies in Melbourne are getting highly benefitted by implementing these technologies in the business.

Here are the processes explained.


CAD Drafting

Gone are the days when the commercial drawing and designing was done by hands. The technique of CAD drafting in Melbourne has made the process simpler and advanced using its applications. This technique is not just used by designers from various fields, but also by engineers, the mining industry, and others for making different parts. The technique is also used in the field of media and entertainment for creating visual effects of realistic and non-realistic nature.

The method provides a very strong base for studying and improving the designs and analyzing them from a wider set of perspectives. These wider observations help in ruling out any mistakes and suggestions for further improvements as well. The software also provides the facility to check the designs in motion and in their full working capacity by way of animations. CAD software in Melbourne are also used for measuring a wide number of equations in their respective motions during motion. There are four types of CAD drafting:

  • 2D CAD Drafting
  • 3D CAD Drafting
  • Solid Modeling
  • 3D wireframe and surface modeling

CAD software enable quality and efficiency in the designs and since the designs are supported by technology, it increases the overall productivity of the engineers.

3D Scanning

Studying a creation be it man-made or natural has become a matter of seconds using these scan techniques. 3D scanning in Melbourne enables capturing the shape, size, dimensions, and other associated details of an object with sheer accuracy using laser light technology. Using the surface of an object, these scanners can create “point clouds” of data. The captured image or design is used for studying for its various applications and they can be amended to enhance their use in a multitude of other functions.

The technique is very much suited for scanning and measuring the contours of complex surfaces and deep geometrics, which can require massive amounts of data to be processed as well as a number of detailed descriptions to be attached to the design. The process for 3D scanning includes the following steps.

  •  Data Acquisition: This is the very first step wherein the object of study is carefully scanned in a defined momentum.
  • Resulting Data: The next is the image of the object that forms using a million “point clouds’ that move together to form an image.
  • Modeling choice based upon the application to which the object is required to be put.
  • Data of point clouds is used for the process of inspection.
  • Then finally CAD processes are used for the purpose of reverse engineering.

3D Rendering

Not just can something be scanned in a 3D model but also be aligned with a scape to mold the entire perspective of viewing upon it. This process is used wherein an alive and original image is required out of material objects or using some of the realistic objects as points of stance for a scene.

Therefore, in this process first of all 3D models of the concerned objects are created, and then the artists set up the cameras, lights, and textures to create the image. Here are the steps to a 3D rendering process.

  • Understanding – The process starts with understanding the client’s vision or the idea of the entire picture.
  • 3D modeling – 3D models are created for the required elements of the final image.
  • Material and Texture – The next step is arranging the entire scene with the required set of materials and designs.
  • Lighting – This is the aspect that brings the image as close to real as possible.
  • Rendering – The rendering process is done when the setup created is captured in an image.
    Final Delivery – After applying the required effects the image is set up for final delivery.

3D printing

Realizing complex structures and designs in the material world is something at the base of creative work and engineering. 3D printing is the process that transforms a design from the computer system into a physical form using the required set of materials. It is also known as additive manufacturing. This is because in an additive manufacturing process an object is created by adding successive layers of materials in a sequence to create the final object.

Each and every layer forms a cross-sectional structure of the desired object. It is the opposite of subtractive manufacturing that requires breaking down an object to form the final structure. 3D printing is a method that enables manufacturing the most complex designs which are otherwise not possible with any other machinery. Here are the various uses of 3D printing:

  • Aviation – In this sector, 3D printing enables the creation of the most complex and delicate parts as a part of designing.
  • Automotive – Car manufacturers use 3D printing for creating spare parts, fixtures, tools, and jigs and also for assembling them in the final model.

FEA analysis

FEA stands for Finite Element Analysis. It is the process that serves as a simulation for any given physical phenomenon using the Finite Element Method. The application is used by the engineers to reduce the number of experimentation and prototyping that they will go through during the entire process of designing and creating any object. Therefore, FEM helps them in saving precious time, money, and effort in the process of creation.

Now, there are infinite numbers of processes that involve in the creation of any object in any field of engineering. These can involve complex weight management, aerodynamic control, fluid dynamics, and a lot of other aspects. This makes the number of experimental calculations exceed far beyond imagination taking much of the engineers’ time. As such FEA analysis brings down these numbers by eliminating the non-productive probabilities by applying a set of differential equations in a matter of minutes.
