Converting .DCM to .STL
Download and install Inveralius Software in the following website
From File, Import DICOM (.dcm) file to InVesalius.
Click Import.
In Select region of interest, within the slider, adjust the right cursor as high as possible, and adjust the left cursor to highlight the area of interest.
Click Create Surface. Wait for the program to complete the process.
Click Next Step.
Click Next Step.
Under Export Data, Click Export 3D Surface and save the file as either .stl or .obj
Open the exported file on Creo.
Scaling Creo Mesh Models
Open the exported file on Creo.
On the "Model" tab, click on "Operations"
Select "Scale Model"
Enter the scale factor
Click the green check mark to accept the scalar.
Click the "References" tab.
Click on "Geometry" and click on your surface.
Click on "Direction" and select a plane in the direction you wish to modify your bone.
Above the reference tab, click on the rightmost icon which shows a rectangular prism with a bulging center.
This starts the sculpt tool.
After the word depth click on the third icon to make modifications symmetrical.
Adjust your view to position the selected plane over the model.
Alter the numbers after rows and columns to get the desired number of editing points on the selected plane.
Select the points which are over the portion you wish to alter.*
Rotate the view so that the plane is perpendicular to the screen.
Click and drag one of the selected points away from the model, and the others will move with it.
The model will regenerate and will be widened corresponding to how far you dragged the points.
* The model will be warped up to the points ADJACENT to your selection. For example if you have ten points in a line and you select points 5-8, then the model will be warped across the area from points 4-9. Be careful when selecting your points to ensure that only the portion you want to change will be warped.
On the "Model" tab, click on "Operations"

Modifying the Model
Since the geometry is defined with mesh, most methods of editing are unavailable.
The only method we have discovered that still works is the "Warp" tool.
Under the "Model" tab, click on "Editing".
Select "Warp".Click the "References" tab.
Click on "Geometry" and click on your surface.
Click on "Direction" and select a plane in the direction you wish to modify your bone.
Above the reference tab, click on the rightmost icon which shows a rectangular prism with a bulging center.
