Modifying Scan Result using Geomagic Design X

Geomagic Design X can be used for modifying scan result such as:

Scale up or scale down a geometry

Creating a shell on a structures

Create a surface mesh of a structure

Adding a new structure on top of an existing structure

Remove a portion of a structure

First, download the Hand.xrl file from (https://drive.google.com/open?id=1dj88Qp...) and open it using Geomagic Design X

Use offset feature (Under Polygons) for scaling up or scaling down a geometry

Under Method select Surface

Select (+) for scale up or (-) for scale down then enter the offset distance

The new offset surface is shown as the green mesh in the window. Select ok (Check mark) to accept the change

The offset feature can also be used to create a watertight mesh

Under Method select Volume

Select (+) for scale up or (-) for scale down then enter the offset distance. Zero offset equal no change in geometry

The new offset surface is shown as the green mesh in the window. Select ok (Check mark) to accept the change

Use thicken feature (Under Polygons) to add a shell on a surface

Chose the thicken direction and the thickness

You can add the thicken inward, outward, or in both direction

If you are applying the thicken into a surface scan, you will end up with a watertight volume (See figure)

First, download the Block.xrl file from (https://drive.google.com/open?id=1-TS8sX...) and open it using Geomagic Design X

A surface approximation can be created to cover the scan mesh

Use Auto Surface feature (Under Surfacing) to create a surface based on the scan mesh

The created mesh will match the point cloud data as shown in the figure

The surface can be converted into Solidworks or Creo for further editing using LiveTransfer

The newly generated surface should be listed under mesh in the left window (See figure)

For a structure with complex geometry, the surface mesh may not working well

Geomagic Design X can be used for adding a new structure on top of an existing structure

Use Add Plane feature (Under Model) to create a new plane where the new structure will be added

You can use the mesh as reverence to create the plane

Use the Draw feature (Under Sketch) to create 2D sketch

Use the previously created plane as reference

Use Create Solid feature (Under Model) to create a new structure based on the created 2D sketch

In addition to extrude, the solid structure can be created using revolve, loft, or sweep.

The newly created geometry is a solid object. In order for it to be combined with the mesh, it needs to be converted into mesh

Use Convert to Mesh feature (Under Polygons) to convert the solid body to mesh

Once converted, the newly generated mesh should be listed under mesh in the bottom left window (See figure)

Geomagic Design X can be used for subtract a portion of an existing structure

Use Add Plane feature (Under Model) to create a new plane where the new structure will be subtracted

You can use the mesh as reverence to create the plane

Use the Draw feature (Under Sketch) to create 2D sketch

Use the previously created plane as reference

Use Create Solid feature (Under Model) to create a new structure based on the created 2D sketch

In addition to extrude, the solid structure can be created using revolve, loft, or sweep.

Use Split feature (Under Polygons) to remove a portion of the structure

Under Method select By Entities

Select the previously created geometry as the subtractor geometry. Then hit the next arrow and accept

You will see a closed hole in the place you subtract (See figure)

The updated mesh file can be exported into stl file by using Export feature

Go to Menu>File>Export to open the export menu

Select the meshes to be exported from the left windows

The newly generated mesh is not combined with the main one. You need to select both mesh (See Figure)

Select the type of the output file and hit save
