I have a scan of a mechanical part as a cloud point iges file. There is another iges file containing the locations of critical points of the part in 3D space, which imports as a 3D sketch. Both files have the same origin, but the origin is not aligned with the geometry of the part in any convenient way.

To build a rough solid model of the part I did the following. Keep in mind I don't need accurate surfaces, I'm trying to create a rough space envelope of the part. I do however need accurate locations of the critical points.

- Imported the cloud point data with ScanTo3D.
- Created mesh, did not change the origin.
- Copied the 3D sketch of critical point locations from other file, with same origin as mesh file.
- Aligned origins of 3D Sketch and mesh. The 3D sketch correctly overlays on the mesh, so I now have a mesh for approximate surface generation and accurate locations of critical points.
- Using the mesh and critical points I have created a rough solid model with critical features in accurate locations.

Because I will be sending this file to a colleague that does not have ScanTo3D I have now deleted the mesh, so am left with just the solid model. The origin is still way off however.

What would you do to change the position of the origin now that I have an adequate solid model?

Many thanks in advance...
