Reverse Engineering Tutorial Step by Step
How to reverse data rapidly when we have the scan data? Today’s article we will share you the method about using geomagic essentials & solid edge to do the reverse engineering step by step.
What you need:
Scan data (please download from https://drive.google.com/open?id=1huXgS6cHWP1wUKxQKLIXmnd9tsNsvbjG)
1. Preparation– Geomagic Essentials
- Delete redundant data.
First, delete the support part data which was captured while scanning.
- Repair mesh
Use Mesh Doctor function to repair imperfections in a polygon mesh automatically.
- Fill holes
Due to the scanning method, we missed some regions ‘data. Use Fill holes function to complete this mission.
- Align to world
Because it deviates from the world coordinate system, to facilitate subsequent operations, we align the data with the world coordinate system.
We need to generate an axis, a plane and a line to help align.
It is very easy and quick to align to world in the software.
2. Generate References– Geomagic Essentials
- create curves
Create curves on the data surface to facilitate after reverse operations .
- Auto surface
This workflow generates surfaces that match the object exactly as it is constructed. Then export igs. file.
3. Construct Model—Solid Edge
- Create curves
Use application button to import igs file. Use keypoint function to draw lines.
- Create surface
Construct both blades surfaces with guide curves and boundery then extend.
- Construct blade shape
Sketch the blade shape and extrude. Use both surfaces to replace and construct the blade shape.
- Construct remain part
Sketch and extrude the center cylinder. Pattern to get 3 blades and round all edges.
