3D object scanning procedures are actually simple, but using the 3D scan data to create CAD models can be challenging. This is why cutting-edge software and hardware are used for CAD model creation to avoid errors while improving product development schedules.
What is Scan Data Based Engineering?
Learning about scan data itself is a good way to understand scan data based engineering. The popularity of scan data stems from engineering advancements. Software and hardware have become more powerful yet affordable for the public, increasing access to scanning technology.
Scan data comes in two file types: mesh and point cloud. Point cloud encompasses millions of points within cyberspace that represent object surfaces. These points are accurately aligned across the object’s structure, so it is possible to achieve highly accurate dimensions for 3D images.
Mesh files consist of triangular forming lines that symbolize points within a point cloud. This means that 3D files will comprise millions of small triangles. SDL is the standard file type for mesh formations; 3D printer users should be familiar with this file type.
Scan Data for Reverse Engineering
There is a close relationship between reverse engineering and 3D scanning. Developers and manufacturers need a way of rapidly analyzing existing structures to reproduce high-quality products. Reverse engineering is also used to solve design challenges, improve existing models and assess competitor products to identify weaknesses.
When 3D scanning is combined with CAD workflow, it supports engineers by enabling them to reverse engineer practically any object. It is indispensable in scenarios where there is no documentation or blueprints. Once an object has been scanned, its accompanying files may be imported directly into CAD software through formats like OBJ or STL.
Do note that 3D scanners currently do not output models which are ready for manufacture. Rather, it only outputs polygon mesh or point cloud data. This means that 3D scanned data has to be modeled further within CAD software. Some tools can transfer scanned data in the form of facets. Individuals do not have to worry about mapping surfaces, manually creating shapes, or making solids.
Is Scan Data Easy to Use?
Thanks to the automation and optimization of reverse engineering tech, utilizing scan data has become easier than ever before. 3D scanners have become simpler to operate, and there are always design and engineering specialists ready to help.
The complexity depends a great deal on data size and desired product functions. Those who handle small SDL files might want to use a specific interface file integration, i.e., graphic body or solid surface.
