In the article Dynamic Cross Section View is Blank, the first solution is destructive, because (at this time, using SS4 .878) not only does it destroy the cross section views but it also reverts all views to the default model.
The second solution could be part of the troubleshooting process when something's missing, but unlikely when the entire cross section is blank.
Another solution--not destructive at all--is to check whether the dynamic cross section view has the active file's own 3D model even attached. You may want to add this solution to the article.
