I’m trying to build this shape and had a problem with the loft not going all around the curves and only on the sides, and when doing offset solid, both side surfaces are going in the same direction. To cover the front and back, I used a list item. When I tried to add another curve, the two surfaces connected to each other. I want to be able to draw curves on a surface and use Surface Morph to flow the shapes on another curved surface.

The box on the left is going into the wrong direction.

Why do you create four separate lofts?

One extrusion would be more efficient.

If you want to loft individually, the direction of the curves need to be right.

Please clarify how the shape needs to look like.

I wanted to create a continuous loft then offset inside, but I don’t know what I did wrong

Yes it’s perfect but when i draw another line the surface connected to each other, My objective is to be able to draw lines that have the shame then morph them to the surface.

Do you also want to be able to use curves instead of just lines?

Thank you. It’s what I’m trying to achieve. Pls can you suggest some tutorials I can learn from to do simple shapes? Really appreciate it.
