Capping Irregular Shapes

Is it possible to cap shapes that do not have planar edges? If so, how would cap the object in the attached file?

Thank you,

In this case Untrim with Keep trim objects Yes and split. There’s always a way. Worst case use surface patch.

if you want near planar surface , split the edges ( osnap knot A,B) and loft (1,2)

patch & network more elaborate

This worked perfect. Thank you!
