1 Presentation 9 PICTURE PROJECTION AND RECOGNITION OF TINDER.

2 Learning Outcomes By the end of this meeting, student will expected to be able to : Student can explain all kinds of projection tinder and draw house remain modestly. Student can yield house projection picture remain modestly.

3 Outline Materi Items 1: Tinder of Trimetric. Items 2: Oblique Tinder Projection. Items 3: Representative Of Seeing House and Cutting. Items 4: Projection Dot, Line and Object at room and area.

4 Trimetric Projection TRIMETRIC PROJECTION Trimetric projection represent modification farther than isometric projection. At trimetric projection there are 3 scale.

10 Dot Projection at Area Level off Projection Dot projection at Area Level off.  = projection area (levelling off) P = dot outside area  P1 = projection of P at area  PP1 = distance dot P to area 

11 Line Projection at Area Level off Area parallel line. Line AB outside area  and parallel area . Line A1B1 is line projection AB at area  AB = A1B1 AA1 = BB1

12 Line angular shape with area. Line AB outside area  and angular shape with area . Line A1B1 is line projection AB at area . AB  A1B1 AA1  BB1

13 Diametrical plump line with area. Line of AB outside area  and is vertical area . Line A1B1 is line projection AB at area .

14 Area Projection at Area Level off. Area parallel with projection area. ABC area is outside of  area and parallel. Area A1B1C1 is area projection ABC at area . AA1 = BB1 = CC1 ABC = A1B1C1

15 Area angular shape with projection area. Area ABC outside  and angular shape. Area A1B1C1 is projection area ABC at area . ABC  A1B1C1

16 Area angular shape with projection area. Area ABC outside  and angular shape. Area A1B1C1 is projection area ABC at area .

17 Projection Object at Area Level off Projection Object at Area Level off. ABCD object is outside of area . A1B1C1D1 is projection object ABCD at area .

18 Dot Projection at Area Level off and is Vertical.  = projection area level off.  = vertical projection area. P = dot outside area  and  P1 = dot P projection at area  P2 = dot P projection at area 

19 Area  and  made to become one area draw with its intersection ( ,  ) considered to be hasp P1P2  ( ,  ).

20 Line Projection At Area Level off and is Vertical. Line of PQ is outside at area  and . Line of P1Q1 is line projection of PQ at area  Line of P2Q2 is line projection of PQ at area 

21 P1 P2  ( ,  ) Q1 Q2  ( ,  )
