Problem with loft in armchair model

Hello everyone!

I am trying to make model of armchair with using loft. I looked video in onshape tutorials but my loft does not want to generate. I think this is problem with sketch, but I am not able to identify problem.

Here is my model and photo with armchair that I would like to obtain. I have two profiles and projected curve for using as a guide but my loft fails if I want to use projected curve. Do you have any idea how to make this seat? I would appreciate your help.




Here is link to my document https://cad.onshape.com/documents/140f204e6d2fe9684642f1e7/w/647aa1ceed274d1f1cff4bef/e/2fa84e8d88b81337e78f771f

    I took a look and you seem to be trying to loft from the back to the front of the seat and then trim away to get the sides to look correct, but this will not give you the correct shape. It would be better if you lofted the edges of the seat and then used surface fills to build the shape.

    Take a look at this sample model of the seat base https://cad.onshape.com/documents/947de2ceb5c7db512ce8dd54/w/20f313a4e1404a47fc55dcbe/e/636c3abe0ba57d3148f44cdc

    Note that I modelled half of the shape and then mirrored it which can be a better approach for symmetric parts as you have to pick fewer entities to create the loft.
