If you are eager to start learning reverse engineering we can offer our free tutorials “Reverse engineering for beginners”. This article will introduce you to reverse engineering of organic forms in SolidWorks.

This paper will be useful for those who are looking for answers to:

  • How to perform reverse engineering in SolidWorks?

  • How to import 3D scan data into SolidWorks for reverse engineering?

In the guide you will learn:

  • Add-In ScanTo3D,

  • automatic and guided surface creation,

  • how to use the Mesh Prep Wizard,

  • how to use the Surface Wizard,

  • surface modeling in SolidWorks,

  • solid modeling in SolidWorks,

  • how to get a solid body from mesh in SolidWorks.

ScanTo3D. Automatic surface creation

1. Let us make sure that the Add-In ScanTo3D was installed and is ready to work

solidworks scanto3d

2. And then import 3D scan data (STL)

3. Next we need to launch the Mesh Prep Wizard and follow its steps

4. We can align the mesh and delete needless parts if necessary

5. Let's reduce the number of mesh faces to cut the time of a surface creation

6. And leave the Launch Surface Wizard checkbox checked

7. We choose the Automatic creation option and move the Surface Detail slider to the left to reduce the surface generation time

8. The red areas are the surfaces with errors. We fix them by adding, deleting or moving the control curves

9. When all the errors are fixed, we finish the wizard

10. We've got the solid body

ScanTo3D. Guided surface creation

11. Now let's launch the Surface Wizard and choose the Guided creation option

12. After automatic partition to sub-meshes we use the brush to redefine some areas

13. The top of the tooth can be reconstructed with a spline surface

14. Let's change the number of the control lines

15. And move some of them to take into account a local curvature of the mesh

16. Now we can finish the wizard

17. Let's create the side surface of the tooth with the Curve Wizard

18. We choose the Section Method and define section planes

19. We've got a 3D sketch that contains the intersection curves. Let's use these curves to create a loft surface

20. We need to extend the surface to intersect the existing one and trim needless parts

21. Next we create a new sketch to trim the other side of the loft surface (the XY plane could be used as a trimming tool either)

22. And close the hole with a patch

23. To get a solid body we need to knit all these surfaces with 'Create solid' flagged

24. We can inspect the absence of a hollow inside the body
