GridPro - Version v8.1 -Mesh Generation Tool for Extrude - Scaling

Faces are scaled to the geometry based on their cross sectional radius while extrude.

Click on Extrude button to open the dialog box.
Select the Corner group under Input Face Group.
Select Surfaces under Reference Type in Guideline section and Input the surface group to calculate the centerline of the geometry.
Select if the geometry is branching or non-branching under the Guideline Path. This option works only for non-branching surfaces and for the Reference Type, ‘Surface’.
Click on ‘Calculate’ to generate the centerline.
Once the centerline is calculated, execute Extrude by clicking on ‘Copy’. This will extrude the given faces along the centerline and also scales it to the geometry cross section for each copy.
