Is there a tool to combine two different sides of a asymmetrical bottle design? Previously used rail sweep in Rhino New to Blender and trying really hard to get myself immersed in it. I've come across something that I can't seem to find an answer for no matter what I google.
Previously I'd use Rhino's command for this, and use a rail sweep to create a mesh between two paths. You select the start path, the end path, and the point of rotation (center). It worked very well in allowing me to create unusual asymmetrical designs in a rotation. I've tried and tried to get something similar to work in Blender but I'm missing something. Please disregard the fact that the highlighted meshes are currently in the same shape, I tried combining them as a last attempt to get Grid Fill to work. No go. Does anyone have any thoughts?
Picture 1 shows a side view of the front profile of my bottle shape.

Picture 2 shows the profile of the side of my imagined bottle shape.

Picture 3 is a crudely drawn visualization of what I'm trying to achieve.

Sweeping the face from one to the other in a seamless and accurate manner. I appreciate anyone's time that can give me some help. Thank you!
you can use the Bridge Edge Loops function. As Gorgious says, make sure that you have the same number of vertices, switch to Edge Selection, select all, press right click &gt; Bridge Edge Loops, and in the Operator box set the Number of Cuts and the Smoothness values:
