  2. e’ e’’ e e 1 2 1 2 1 1 x x 2 2 Risanje ravnine, ki je podana s presečnicama a in b. Slednice ravnine določimo s pomočjo sledišč. Sledišča so točke, kjer premice prebadajo projekcijske ravnine (tlorisno in narisno) a’’ b’’ 3’’ 33’’ b’’ 4’’ 44’’ S’’ S’’ E S Ex 1’’ 2’’ 1’’ 4’ 4’ 2’’ 3’ 3’ b S’ Ex S’ a’’ 1’1 1’ a 22’ a’ b’ b’ 2’ a’
