Hello, when trying to make a loft it ends in strange shape. Please help.I want smooth and flat surface between sketches.

@mechanical cad, You can create flat and smooth faces in loft by two method
 I) By selecting match vertices option in loft for that you have to create point on circle.
II) By creating and selecting guide curve in loft operation.
Refer below thread also which will help you to create loft.

@mechanical_cad You will need to work out creating planes between your spheres if you want to do guide curves. I find it easiest to draw lines tangnt with your curved spheres. then use these to create planes using 3 point technique. Then create your guide curves using pierce to constrain end of guide curve to your existing spheres.

Hi to all, @_Dave_, I have some success but it's still not perfect. It looks like it's too complicated to make this loft in Onshape. I made it just in a few clicks in Solidworks and it looks perfect without any guidelines. Here is the link to the document:
