I have found that in many models the Etabs draws secondary beams with their extreme points a little out of line with the mean beams, if they are not orthogonal. When I check the model the report says it is correct, but when I do analysis program reports many points with lost digits. If you move some point of the mean frames the problem will be greater. It is very difficult to find out the problem, that now is not a structural task, it is a drawing work.

How could I avoid this problem?
