CAD/Vidya is a critical tool used to develop EVA suit prototype pressure garments by allowing the lab to create virtual garments that can be simulated on 3D mannequins.
To create the virtual garment, we first create 2D drawings of the garment pieces through the CAD software. They are then virtually stitched together with the appropriate seams. CAD allows for the designed garment to be graded for different body sizes, which presents opportunities to explore the custom of EVA suit sizes. Once the virtual garment is complete, it is sent to a separate program in the software toolbox called Vidya.
Vidya software allows for the garment blueprints to be simulated in 3D on a mannequin with realistic draping, allowing us to visualize how the garment fits on a person. Without Vidya, a significant amount of time, money, and energy would need to be spent tailoring physical garments through trial and error. In addition to realistic draping, this software can generate body mappings of the garment with respect to helpful metrics like distance to the body and lateral (weft) stress. Vidya is also capable of layering garments, which the lab can use to simulate the interaction and fit of a multi-layered EVA suit on a virtual human. This software is especially unique with its capability to create avatars from scans made by the Vitus scanner or 3dMD systems. Any garment model can be created, modified, and visualized with two simple scans.
