Design is a key aspect of developing, modifying and improving instruments. AutoCAD drawings are developed to create a visual representation of the instrument according to the given specifications. Ohmart/VEGA goes beyond these standard 2-D drawings and uses Autodesk® Inventor technology to create 3-D models of instruments and mountings. This 3-D modeling is created precisely to specifications and can assist engineers in troubleshooting potential problems before the system is ever installed. These models are extremely beneficial assets in finding the best system to fit a given application.
