One source of unsupported geometry can be connected with your MSA (Minimum Support Angle) I use 50 degrees. Any surface with a slope less then a 50 degree angle receives supports. This parameter can be adjusted when you click the support generation icon in Lightyear1.x I have seen colegeus use a MSA as low as 32 degrees.
Hope this helps.
