The Shell tool has two major functions. The first is to create a 'Shell Region' which can be downloaded and 3D printed. The second is to create a 'Flare' at your proximal trim lines.

Shell Region for 3D Printing
The [Shell Region] option was made for 3D printing! Simply select the region you want to print, create a shell, and download the mesh to send to your printer.
Step 1: Click the [Select Region] tool.
Step 2: Left-click on the mesh to select the region you want to print.
Step 3: Click the [Shell] tool.
Step 4: Specify the thickness of the shell and click the [Shell Region] button. This will create a new mesh with smoothed edges.
Note - Toggle the 'Smooth Trim Lines' option off to keep any rough edges.
Step 5: Click the [Download] button and select the appropriate file format for your printer.
Flare for Trim Lines
The [Flare] option allows you to create a ridge around the selected area. This is particularly useful for creating ridges at your trim lines for positive models.
Step 1: Click the [Select Region] tool.
Step 2: Left-click on the mesh to select the region where you want to leave a ridge.
Step 3: Click the [Shell] tool.
Step 4: Specify the thickness of the ridge and click the [Flare] button. This will create a ridge at the proximal.
Note - Toggle the 'Proximal Flare Only' option off to create a ridge around the whole area.
