[Archive] problems about 2D thin surface groups editor

Message by Guan Yibing:
There is no 2D thin teared surface mesh model to be choosed for the “teared surface” group after splitting the thin surface in the version “Spis-5.1.8-win7-64b”.
So which surface model should I choose for the ‘teared surface’ group? Is the “spacecraft default” Ok for the ‘teared surface’
