We have done a projects which have huge asemblies consisting of many parts.Several sheet size drawings are released . Our target is to receive all these drawings automatically with help of automation of design & drawing which consists of CAD customisation,Solidworks customisation and Excell based user interface.In AutoCAD ,GA is initially prepared and the next step is to achieve all the required drawings . In solidworks also,assembly model is prepared and the required part drawings are achieved from the model.My working area is to develop 2D drawing and 3D model using Automation and solidworks modelling.The main advantage of automation is reduces manpower and time consumption.We can automate and customise the drawings output with 95 percent of accuracy.
