All Topics In This Article.What Is CADCAD is a computer application which creates virtual 2D / 3D design so that you can validate your design in computers rather than going for costly prototypes. It automated the design process and bring a lot of speed to the design life cycle. Earlier people to do hand sketch or used to make engineering drawing by hands.
History Of Cadd
CAD replaces that concept and now everything gets virtually created in your computer using CAD software. Why CAD?Industries use CAD mainly for the following reasons. However, this list shows just a few. The micro-level impacts are much better than what we can write here. Speed up the design process. Virtual mock-up of designs. To make error-free design.
Validating design. Reduce project turnaround time. Automated the design processAlso Read:Difference Between 2D and 3D CAD2D CAD is a two-dimensional approach where design or drawing is made in a two-dimensional environment. What that means is that design or drawing only shows the X and Y coordinates.3D CAD is a three-dimensional approach where the design is made in a three-dimensional environment. So along with X & Y, we need to use the Z coordinates also in the design Evolution of CAD software.The research was going right after World War-II to bring up some sort of automation to the design cycle so that design can be done faster.
The actual breakthrough industry got in the year of 1982 when AutoDesk launched Auto CAD.Entry of AutoCADAutoCAD is the first 2D CAD software which brought revolution in the industry. Industries started seeing a good benefit from Autodesk and soon it becomes the widely used CAD software. AutoCAD shows the path to many companies and they started feeling the huge potential in the CAD software.
Launch of first Parametric CAD software: Pro/ EngineerAutoCAD was initially only offering 2D drafting facility. A need for a 3D CAD system was there in the market and in 1987 we got the software which created a benchmark in the industry. In 1987 PTC ( Parametric Technology Corporation) released the first version of Pro/ Engineer. It was the first 3D Cad software which was purely based on Parametric modelling concept.Pro/ Engineer was based on solid modelling and use Parametric concept to create a parent-child relationship in the 3D model feature tree. Pro Engineer had an intuitive interface and that was the deal breaker for many industries The dominance of CATIA and Pro / Engineer1988 saw a major breakthrough for CAD software when Boring announced that they will use CATIA to design their Boring 777 aircraft.
That generated about $1B revenue for Dassault System who supplies CATIA The entry of the leader: SolidWorksThe late ’80s and early ’90s were dominated by Pro E and Catia until 1995 when the SolidWorks came into the market. SolidWorks was a big turning point for the success of CAD software. Earlier people used to believe that leading CAD software is very tough. And in fact, it was true. Pro E or Catia both were not user-friendly and was very tough to learn.SolidWorks simplifies the way CAD software works and it was very to learn even by newbies who entered recently into CAD industry. SolidWorks also works on the same parametric approach and a very simple and I future interface. Soon after launch, it becomes very popular and people started using it as a replacement of Pro E.Solid Works was bought by Dassault System after seeing the massive success of SolidWorks.
The entry of other CAD softwareThe success of CATIA and Pro E and Solidworks created a healthy competition in the market and by the end of 90, there were a dozen of CAD software launched. Out of that Unigraphics, Solid Edge and Mechanical desktop got a good response from the industry.By the end of the ’90s, we see a downfall of innovation in CAD software. The software was many but all were providing the same set of features. To differentiate companies started focusing on new technologies and that’s how PDM ( Product data management) software was born.
The PDM eraEarly 2000 did not see any major CAD software release. Small CAD companies were taken over by big companies and finally, the list becomes compact as nowadays there are only four companies who dominate in the CAD market. PTC, Dassault Systems, Autodesk and Seimens. Since there was not much innovation in CAD in early 2000, focus changed to develop PDM software where users can see 3D files in a browser.Companies like PTC launched PDM link and Wind-chill. Siemens released the team centre. If we look into 2019 the focus is now changed to MBD ( Model Based Definition).
Father Of Cad
All companies are trying their best to step into MBD which slowly becoming the industry trend. Wrapping Up!Market need changes very often and that changes the feature list that CAD software provides. With no or little innovation in CAD, the trend is getting focused on other automation with a focus on the market need.That’s all we have in this article.

This paper reviews the concepts associated with building modeling, as the most effective means for using computers in architectural design. Building modeling integrates the multiple representations used in architectural design. The requirements for a system to support building modeling are outlined. Means for using current CAD systems, so they provide the approximate capabilities of building modeling, are presented. Consideration is placed on pedagogical implications and the opportunities for schools of architecture to make contributions to the practice of architecture. Previous article in issue.
