Mechanical Engineering can be a rather complex field of work. In the modern context, there are much software tools that can assist a mechanical engineer in his or her work. These tools include programs such as CAD (Computer Aided Design), Thermal analysis, FEMs applications.
Computer Aided Design tools can range from comparatively simple 2D Technical Drawing and Drafting programs to highly complex associative and fully integrated 3D modelling programs.
2D Drafting Programs includes tools such as Solid Edge 2D, Draftsight.
On the other end of the range scale are highly complex parametric and/or fully associative 3D-based CAD systems. These tools often have solid modelling, surfacing, assembly and 2D drafting capabilities.
This include tools such as:
1. Pro-engineer
2. Solidworks
3. Solid Edge
4. Autodesk Inventor.
This types are tools are very powerful and can allow the Engineer to work in virtual 3D, which are closer to the physical world than mere 2D drafting programs. Furthermore, this tools also enable the 3D designs to be translated into 2D Technical drawings with far greater ease than manual drafting. When the 3D designs are modified, the corresponding 2D drawings often will reflect these changes and updated accordingly. With proper usage, these tools can save Engineers alot of extra work. Smart programs.
Between the pure 2D tools and the fully associated 3D packages are dedicated programs for precision 3D modelling. This range include programs such as Rhinoceros 3D. Below video shows a generic process of Rhino created design being downstreamed to another engineering tool.
It should be mentioned that a software tool do not really help an Engineer to design. It is mainly extremely useful in assisting him in virtually-evaluating, verifying, organising and communicating his designs. In another word, these tools cannot take over the Engineers job.
