Convert polyline wire frame to surface

[Edward.DaltonHXMUQ]

I have a bunch of 2D polylines arranged in 3D space.  I need to convert this wireframe into a 3D surface and that surface needs to be smooth and touch every intersection.  The only way I've found to do this is to BREAK each polyline at every intersection, then create a surface in each small box.  Obviously, this is very time consuming and very clicky.  I've tried using MBREAK.lsp and the intersection code from Lee Mac, but all seem to require the polylines to live in a 2D plane.  Is there an easier way to do this?  Please, don't suggest alternative software as AutoCAD 2019 is all I'm allowed.  TIA

1. Create single polylines for several of the radial sections.  See the 3 red polylines in the image below.
2. Use one of the XZ plane polylines for the guide line (e.g., the cyan line).
3. Give the loft command and select the 3 red lines, hit Enter, then enter G (guide) and select the cyan line.

Use the same approach for the ear guard and edit the resulting surface as needed.

Rather than use 3 radial section you could use each and rely less on the guide curve to get the transverse smoothing.
