In Concept, to take print outs of Section/s go the the menu File|Print and when the pop-up page "Document Contents" gets displayed select the Section/s that are required to be printed. All the objects in that particular Section/s will be printed out.
In Unity, to take the print out of any Section, first you will have to open that particular Section and then after issue the print command. This action will give the print out of that particular Section with all the objects present in that Section. So in Unity Program Section print outs can be taken one at a time only.
