Issue:
Why doesn't my loft have a smooth transition? It isn't lofting as I expected it to.
Cause:
This is due to using the Section Body block as the input.
Solution:
Open up the Properties of the Section Body block and drag out the 'Polygon' chip into the inputs for the Loft. This allows the Loft to be more robust since it is using the polygon (profile) of the Section Body. Watch the gif below to see how to fix your loft.
