So, I had to use loft while back to create some organic shapes, I wanted to predict what kind of curves the loft would make and what kind of curvature math it’s using. I found out it’s using something like FIT SPLINE, because as you connect curve it changes based on the next connection.
You can eyeball if you want the curve the way you drew above, you drew a curve and put circles as a guide, you would need to now use control spline and eyeball around the desired thickness.
If you don’t want to eyeball it you can use fit spline but that will give you different results which is based on some curve math but will be working around the end point you give it.
So it will look like this.
The other example I used Fit Spline.
