3D View is used to draw regions of the turbo assembly for visualization purposes. It is not intended to be the basis for quantitative calculations. Select the regions that you want to draw.

After creating the blade-to-blade object (select the Three Views toggle in the Initialization object), you can view the blade-to-blade object in the 3D View object by setting the appropriate option in the 3D View object.

Note that you can view chart location lines in the 3D View object by setting the appropriate option in the 3D View object.
