The skills and software tools
The skills and software tools available to mechanical design engineers and mechanical drafters, and as a result of 3D modeling CAD services and design in general have come a long way since their early days in the late 90’s and early 2000’s. 3D design software is very advanced and extremely efficient in creating drawings quickly and accurately. Designing in 3D versus 2D saves your project incredible amounts of time and possibly wasted money down the road by making sure all parts fit perfectly in a 3D virtual environment. 3D software can analyze the assembly and determine if there are any interference’s before making any physical parts. Once the interference’s are found, the 3D model file can be modified to eliminate interference and a clean functioning design will be manufactured. Before 3D CAD software existed it was very common for a designer to overlook interference and discrepancies especially in a complicated design prior to manufacturing. With 3D CAD software, this is no longer possible.
3D CAD software also does very accurate FEA/FMA analysis. FEA (finite element analysis) is the process of determining a part’s strength. Do it’s dimensions need to be bigger or smaller for the intended design purpose? You can easily determine this with FEA by inputting the expected forces, materials properties and many other variables and save materials, manufacturing time and project cost by making very efficient parts!
Some popular 3D CAD software products we use include; Solidworks, Autodesk Inventor, Catia,Unigraphics NX, Pro-E Wildfire, SolidEdge, AutoCAD and Microstation. Basically each software package offer the same features. They all have similar functionalities but each software is better at doing different things, however, most of the parts J – CAD Inc. creates are done in Solidworks, Inventor or Catia.
