Hi everyone, while modelling, it happened several times that some functions break after changing something to "parents". Example: I draw two surfaces, blend them succesfully and I go on, Afterwards I decide to modify one of the "parents surfaces" into Edit Points, when did it, the blend disappear and the exclamation point shows off near it in the tree. Sometimes the function remains broken even if I undo the operation!!!! It seems a sort of refreshing problem.... is there a refresh/redraw command? thanks!
