I currently can't sphere/cylinder map this type of chart/cuts

[ggaliens]

Code:

find_axes(Fs,BEdges,We) ->
    ChartNormal = chart_normal(Fs,We),
    case forms_closed_object(BEdges,ChartNormal,We) of
    undefined ->
        throw(
          ?__(1,"I currently can't sphere/cylinder map this type of chart/cuts,\n"
          "I can't figure out which axes you want as X,Y, and Z,\n"
          "please use unfolding or one of the projection mappings."));

%%        find_axes_from_eigenv(Fs,ChartNormal,BEdges,We);
    Nice ->
        Nice
    end.

In my manifoldlab releases folder is a dense sphere with cutlines.

It is very similer to one that has about 1/2 as many polys ... but the same structure ... which did UVMAP.

What sort of things might throw off the axes finder ?
