Stretching boxes with curved edges?

Hi guys,

I've got a bit of a problem here. It's probably just going to be solved with the correct function again, but since I can't really tell how you'd call a function like that I can't find any solution.

When I started to model things I usually relied on destructive methods, so many boolean operations. Later I used a lot of symmetry and pivot movements. And for current projects I moved to modifying the vertices, edges or surfaces of poly modifiers to form an object into the correct shape.

Now I'm stuck with a problem where I require a very symmetric shape and I fear that I cannot just model it correctly by hand only. I could rely on destructive methods again but I was rather hoping for an alternative route.

It's about having a box, where one side is bigger than the other one.

I can select the side and just use the scale tool and stretch it. That will give me a box with either a smaller or a bigger base. But the lines connecting the smaller and the bigger square side are always straight.

Is there a way to get a curved side, much like it's done with bezier curves for the spline tool? I know there is a stretch modifier as well, it works great on a sphere to get a similar shape to what I was looking for. But when I do that on a box it doesn't work. The modifier itself however shows exactly that operation that I'm looking for.

I've also added a picture with what I'm getting and what I want. The third picture was done using a boolean to show how it is supposed to look like. Is there any way to do this any other way than cutting it out or modelling it by hand?

Many greetings and thanks to all ideas,

Martin

Yes, I would in fact start with the line tool in orthographic view and set the key vertices to bezier corner and then put an Edit poly modifier on top and extrude. Has the virtue of being non-destructive also. See screenshots below for workflow.

Edit poly based on bezier curves from spline shape.

Hope this helps.
