Is there a way to fill this space in nicely and smooth?

New to this forum, but not to Rhino just not an expert. Need help with filling in the driveway but it needs to flow with the topo.

Is the driveway needed for illustration purposes, or does it need to accurately represent the final surface including crown, etc.

How closely doe it need to conform to the topo along the boundary?

One approach for illustration purposes would be to use Patch with the edges of the existing surface as input. You may need to experiment with the number of spans in each direction and the stiffness parameter.

It doesn’t need to be perfect since I know nothing about road design, just needs to fill into that space so it looks smooth in Lumion. I’ll try patch now , thank you.

It worked! Thanks again
