Why I can’t shell this loft object please help

Did you try to maybe offset the angles of your current shapes and loft only the edges, leaving a empty shell in the centre.

I tested this and it does not work, so i went back to the drawing board.

What I did was I made 4 sketches as seen below.

I then made an offset of each sketch as shown below

I lofted both sketches making two bodies.

I then subtracted the smaller one from the bigger one and got my final product.

I am still new to S3D and plan to purchase it one day.
