Details
Edge Blend does not work like described online documentation.
If Trim Blend option is active, Edge Blend is possible.
As described in the online documentation, edge Blend should work here without selected option Trim blend.
Solution
he documentation works as stated.
With "Prohibit Roll on Edges" selected, that negates the Roll on edges option.
If "Trim Blend" option is OFF, the cylinder cannot extend to trim the blend that you specified could not roll on the edge. So "Trim Blend" must be ON to work.
The documentation does not explicitly say "Trim Blend" option ON to get the result. You need combine "Trim Blend" option and "Prohibit Roll on Edges" documentation together to get result.
