Hi Brian
>> Is there some other Sweep,js that needs to be deleted?

If you have the same result with Barry's, you've replaced it correctly.
"Sweep" node is inside the "Construct.js" file. (Line 28)

Salut,

So, with a little perseverance, I've arrived at a result that suits me as far as the shape of a chocolate candy mold is concerned (even if the dimensions aren't exact - I couldn't find anything on the web!).
My problem with the proposed solutions was the connection between the rising curve and the upper part. But Barry's and RebuildSurface's suggestions were a great help.
