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)

Software: Geomagic Essentials+Solid Edge Shining 3D version 

Let’s start.

 

  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.

 

  1. 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.

 

  1. 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.
