As shown above, I already have two curves in place (one on the top face, one on the side). I am hoping to insert a third transition curve (shown in red between the two blue ones) then join all three and perform a sweep cut. Could someone please help me out with the correct steps to follow. I am somewhat new to Creo and I have tried to get things this far on my own but am hitting a wall. I have tried using "projection" on the middle curve to wrap it round the plane but can you intersect projections with curves?
Maybe there is just a specific order I should be following and starting with two curves either side and trying to join them is the problem?
All help greatly appreciated!
