Sometimes you don’t have access to a part’s original design documentation from its original production. Reverse engineering empowers you to analyze a physical part and explore how it was originally built to replicate, create variations, or improve on the design. The goal is to ultimately create a new CAD model for use in manufacturing (3D printing, metal casting, injection molding, welding, etc).
Reverse engineering, sometimes called back engineering, is a process in which software, machines, aircraft, architectural structures and other products are deconstructed to extract design information from them. Often, reverse engineering involves deconstructing individual components of larger products.
The first part of the process involves using a 3D scanner to collect the geometric surface measurements of an existing part quickly and accurately. The scanner typically outputs 3D scan data as dense triangle mesh in OBJ, PLY, or STL Mesh formats-anywhere from a few thousand to millions of polygons.
You can use it to replicate the part or create a new design based on the original. 3D scan data serves as a visual guide for sketching the CAD drawing. It’s pretty much tracing right on top of the scan data. You want to start the CAD drawing with tracing basic 2D sketches along with creating standard relationships and constraints in order to maximize control over how your design is developed. 2D sketches are then converted into 3D featured bodies or surfaces (extrude; revolve; loft; sweep). You continue to build out all the part’s features until the final CAD model is created.
There’s no magic button for converting a 3D scan data into a usable CAD file automatically. But there is a standardized workflow that makes reverse engineering a straightforward process.
Geomagic Design X creates CAD models from 3D scans faster, more accurately and reliably than any other reverse-engineering software, enabling you to create new business value out of existing products.
• Processes large scan data sets with millions of points faster than any other reverse-engineering software.
• Creates complex hybrid 3D models for solid, surface, and mesh.
• Connects directly to your CAD environment and creates native files to accurately represent a scanned object.
• Rapidly creates solids or surfaces just like in CAD.
• Transfers 3D parametric models with full design history directly to any popular CAD software.
This video presents a Design X modeling of a simple centrifugal pump casing, also it shown some simple inspection analysis in Contorl X.
It took 4 hours to model this part in Geomagic Design X from scan.
