The competition takes a good hour to get 'sort of' right along with a dozen commands and sketches.
With ZW it is a single click on the fillet command. ZW definately has bragging rights for the power of their offset fillet command.

Here is another simple - short history - way of getting a blend curve with more control that you have with the offset fillet.
So base, set up trim curves using wireframe tools, then trim to curves then a loft.The power is in the loft and being able to regulate the tangent influence for each face. My favourite tool.

Showing the short & easy history.
I am sure there are many other solutions, but most importantly ZW3D allows for some easy and fast surface modelling.

e.g. Edit the edge offset curve to create the irregular outline, then do the same for the adjacent. (OK I cheated and did a single curve trim) Now we have something a lot nicer and the only additional effort is editing the trim curves.
Now complete the loft, add and modify some loft control lines as the edge lengths are quite different and you have something much curvier.

There are numerous ways to create curves on a surface. I just used and edge offset, which is then a 3D Curve. You can edit the curve to create what you want. The trick is to make the tolerance for the point reduction quite high say 50, then reduce the number of points to something you can manage manually.
In reality, it would probably be easier to do a sketch which would give much more control and editing possibilities. If the surface is planar then the Trim with Curves In place option works, otherwise you need ot project he sketch to the surface.
The model explains it self.
LOFTs - read the help. It is worth learning to manage lofts.
This video is quite long but the lofting is demonstrated early on: https://www.youtube.com/watch?v=xXKZ_2rtEdY
Getting the profile connect pick points aligned is a good starting practice. e.g. both start arrows about the same place and pointing the same direction. Occasionally this is difficult and splitting an edge may be required to set this up nicely.
Once the loft is in place, Add Connection lines. Make sure your pick setting (RMB in modal space) on All and non critical. Then just click on an edge where the loft is most wonky or out of shape. Add 2 or three for a start. Then use the Modify to move one end or the other of the Control line to tell the loft how it is to align at that point.
You can also play with the tangency controls at each end or both ends simultaneously.
The other trick with lofts is that rather than lofting between solids, always remove the face that would be buried and loft between surface edges. this way you get full tangency control. You will use curve lists a lot to collect the set of edges you are lofting with.
Then there are the Bi rail and Drive Curve Lofts! If you an popular solids modeller user, you might find the loftin g in ZW works roughly 90deg different to what you are used to. e.g what you would thing of is a profile, should be a drive curve. Huh...!
