Today’s growing need of bringing down product development time is evidently felt more in the aerospace industry. The major contributing factor to keep product development schedules short is to have a strong digital design process in place.
Traditional Mylar sheets do not help in deploying information quickly. Besides, these sheets fade away with time, making it difficult for the design engineers to recover legacy design data for critical aircraft components. Digitizing these mylars is eventually the only possible way out to ensure that the design data can be leveraged as an when required. Converting these drawing sheets however requires considerable investment in terms of equipment purchase for scanning and hiring resources for CAD modeling.
Aircraft development firms however can also choose to outsource the CAD conversion task to engineering service providers, rather than making costly investments. Either way, the need for developing digital drawings is essential.
The ability to readily update the CAD drawings and models as per the design requirement is one of the prime benefits of digitization. Furthermore, when detailing about what CAD offers, one of the amazing factors is for maintaining accuracy of drawings and 3D CAD models same as that in the original designs. On-screen rulers allow creating precise and accurate geometric models and measure the dimension without physical inputs. CAD electronically compensates for the errors, which are encountered in five to ten inches of drawing to restore the original dimensions in the drawing. Changes and modifications in designs can be done freely by automatically updating in geometric relations maintaining the design intent.
Moreover, with CAD conversion and final 3D CAD models, replicating designs become easier and with enhanced value addition. The direct editing capabilities empower the designer to dynamically change the patterns and evaluate them for different phenomena for exact results with precision. Drastic changes like entire mounting bodies can be duplicated without many efforts.
One of the most required design assistance in aircraft industry is to make the designs with less material weight and better functional performance. For this, constant experiments to upgrade the designs are done to attain optimized result. With SOLIDWORKS, designer can rapidly explore design ideas make impressive edits and prepare imported data. With powerful tool of on screen triad in SOLIDWORKS, features in 2D can be moved rotated or translated.
Triads can be used as per the convenience to separate the bodies and duplicate it entirely to simulate the model under different conditions. The important geometry manipulation allows you to create and achieve better results through design optimization, virtual environment based simulation and file database management. File management like Bill of Materials and manufacturing-ready drawings for fabrication can be generated through these 3D CAD models.
However, many other tools apart from SOLIDWORKS also work just fine in designing and achieving the results that serve far more than what paper-based drawings can do. Bottom-line is that Mylar sheets based drawings may have had held the legacy for drawings, specifically in aircrafts structural designs, but today, design engineers from the industry definitely resort to CAD models and essentially convert the readily available designs on paper to 3D CAD models for their accuracy, technical and product development benefits and multi-layered quality control checks.
