Creating surfaces from curves

[mariustipa]

Hi

I need to create a surface from the curves attached bellow. In the next stage I will place a semisphere on the top of the horizontal circle. The entire surface will be like a church dome. Does someone have the slightest ideea?

I have tried with NURBS but I have zero experience about NURBS ... Is this the right way to approach?

You could create a sphere, and slice it with four planes on the 4 side and two planes for the top and bottom

Adding to @truckexpert 's excellent suggestion, center a sphere (within Hemisphere set to 0.5) of radius 1.414 (square root of 2)  at 0,0,0 then position the slice modifiers at x=1, y = 1, another at x = -1, y = -1. and a third at z = 1.

But I also need the 4 side walls. Now we have 4 gaps there.

1. Create a hemisphere of radius 1.414 located at 0,0,0.
2. Create a box with a width of 2, length 2, and height 1
3. Use Proboolean Intersect to get the final shape.

Seems to be the solution. Thanks!
