How do you offset asymmetrically?

offsetsurface

#1

Hello, rhino users. Greetings!
I am trying to offset this curve, but not equally on all sides. Is it possible?
I drew this curve first

Then i offset it and got this

But, what i want the offset is like this black line i drew on top of the model

How do i go about doing this? I have also uploaded the 3dm fileif anyone wants to check out the model

Many thanks for reading.model.3dm (210.0 KB)

Hi Ankit- yours is probably too extreme for this but one way would be to Pipe the curve with multiple radii and then Intersect the result with a plane. In this case, I thing you’ll need to construct the curve from two offsets and some added transition curves.

Hello, thanks for clearing. Maybe is should draw two separate curves and then extruded both?
