how to make 3d sketch line into surface?

Hello GrabCAD member, i have problem to make surface from my 3d sketch (red line - picture attached below). Can somebody help me to solve this?
The purpose is to create surface plane to split the solid object, so i can delete which i don't need one.

Thankyou so much to GrabCAD and all member

There are probably several ways to do it, the way I would try first is to use 3 separate sketches (instead of one 3d sketch) and make a surface loft between the 2 longer sketch profiles and use the short profile as a 'guide curve'.

3 seperate sketch mean that make the first curve in 3d sketch,then exit sketch.After that make a new 3d sketch for the 2 guided curve...

Vous pouvez aussi lisser une courbe jusqu'à un point seulement avant de lui assigner les courbes guides
