3D Design Tutorial: Blender as CAD Tool (Shelling)
#blender3d #productdesign #CAD #IGES #manufacturing #computeraideddesign
The purpose of this tutorial and demonstration is to highlight the potential of Blender 3D as a CAD-like software. The video showcases the process of creating even-wall thickness or shelling, and also provides a demonstration of exporting manufacturable IGES files. FreeCAD integration is also demonstrated in the demo.
In product CAD modeling, shelling refers to the process of creating a hollow space or cavity within a solid 3D model. It involves removing material from the interior of the model while maintaining a consistent wall thickness throughout the outer surface.
Shelling is an important technique in CAD modeling as it allows designers and engineers to optimize the weight, strength, and manufacturability of a product. By creating a hollow interior, the overall weight of the object can be reduced without compromising its structural integrity. Additionally, shelling enables the incorporation of internal components, such as wiring, piping, or other functional elements, within the product design.
IGES stands for Initial Graphics Exchange Specification. It is a neutral file format used for the exchange of 3D CAD (Computer-Aided Design) data between different software applications. IGES was developed in the 1970s as an industry-standard format to address the problem of interoperability between various CAD systems.
The purpose of IGES is to provide a common language that allows different CAD programs to exchange 3D geometry, as well as associated data such as annotations, dimensions, and other design attributes. By using the IGES format, users can import and export 3D models across different CAD platforms, regardless of the specific software they are using.
