AutoCAD is widely used by architecture and engineering firms for designing buildings. Both software programs can be used for creating plans for construction, they have significant distinctions. AutoCAD is often viewed as a rival product, however they actually complement one another, and both are provided by Autodesk. The main difference between these programs is that AutoCAD is an drafting tool that is a representation of structures based on their geometrical shape. MEP CAD however, on the other hand is a modeling software where components of buildings are identified by their functions. The model could contain technical specifications and pricing data. For instance air ducts in AutoCAD are just lines that show dimensions and layout. On the other hand, HVAC CAD can identify ducts as Plant 3D system components, and their respective specifications. These features permit HVAC CAD to function as a Building Information Modeling tool (BIM) which is not available using AutoCAD. The HVAC and AutoCAD CADs: Brief Background of each SoftwareAutoCAD has been around for a longer time than HVAC CAD the initial version that was launched by Autodesk in 1982. AutoCAD is regularly updated since its release. The latest version includes cloud storage and compatibility with mobile devices. After being in existence for nearly four decades, AutoCAD has positioned itself as the market leader in drawing software. HVAC CAD Technology Corporation launched the first version of HVAC CAD in 2000. Its name is a contraction for "revise it". HVAC CAD goes beyond simple draftsmanship, allowing the creation of intelligent building models within a virtual environment. Autodesk acquired HVAC CAD Technology Corporation in the year 2002 after recognizing the potential of the software. Overview of AutoCAD AutoCAD can be described as a digital drawing tool, which means that the drawings are rendered geometrically. AutoCAD is a program that depicts all the elements of a building as geometric shapes. There are no details regarding their physical properties or the way they interact. Let's imagine that you have four different views of the same building. Because you are using a geometric representation, any changes to one view will not have an impact on the other. Each view must be edited individually to reflect changes. For this reason, AutoCAD is a great tool in 2D drafting and precise linework, however it's not an instrument for building design. AutoCAD can also generate 3D renderings and models however they're still purely geometric models that lack specific information about the component. AutoCAD design requires collaboration between engineering teams. Any changes have to be carried out in a separate manner. Before you make any modifications you should ensure that it is not in conflict with building systems being designed by other teams. When is AutoCAD recommended? AutoCAD is effective when working with renovations and upgrades in existing buildings , where the initial construction plans were also drafted in 2D. The software offers excellent compatibility with different versions and working with older version isn't a problem. Many engineering and property management companies have large collections of AutoCAD documents in DWG format. This makes it difficult to create HVAC CAD models to be used in these projects. Keep in mind that when we are executing the 2D or 3D modeling or design project, we also need a good workstation, along with quality accessories such as mice for CAD and 3D modeling, apart from powerful software. There are a variety AutoCAD alternative, available on the market. AutoCAD's latest version now supports the integration of PDF. This is a useful feature for construction plans that aren't accessible in DWG format. AutoCAD is able to import PDF files and transform the files into DWG and then identify linework and text. AutoCAD can be used to share views via cloud-based technology. Views can be viewed by other employees, without having to install the program. AutoCAD has been updated to be compatible with 3D printing, making it simpler to design prototypes. HVAC CAD Overview HVAC CAD is a tool for creating 3D models of buildings. These include not only geometry but also the physical properties as well as the interactions between the parts. HVAC CAD also makes modifications easier, since the design teams of all departments are working from the same model. If a plumbing project occurs in conjunction with HVAC installation, HVAC CAD will immediately be aware and inform the designers. HVAC CAD allows for the management of changes to be much simpler since changes are immediately reflected in all views. AutoCAD might require designers to make changes to several files for them to be updated. This is a major advantage of HVAC CAD. Project documents can be completed faster. The HVAC CAD software is beneficial when you are removing materials or preparing bids. It can automatically generate cost schedules due to its technical specifications and component pricing. HVAC CAD disadvantage. The building model has to follow a set of rules. This rigidity can be used for drafts and 2D views. If you are working solely with linework, AutoCAD offers more flexibility to modify views as needed.
