ORTOGRAFIESE TEKENINGE

OPDRAG 1:

Teken ‘n ortografiese aansig van jou voltooide houertjie.

Table 1
         
  LU/AS 1.12      
         

Wat is ‘n ortografiese tekening?

Dit is ‘n metode om ‘n voorwerp korrek vanuit verskillende aansigte te teken. Elke aansig word geteken asof dit ‘n plat vlak is. Gewoonlik word ‘n figuur vanuit drie aansigte geteken, nl. die vooraansig, die sy-aansig en die oorhoofse of bo-aansig.

a) Hier onder volg ’n aantal 3D-figure. Langs hulle is telkens drie vorms. Dit is hoe die figuur van voor, van die kant en van bo sal lyk. Skryf onder elke 2D-vorm of dit die beeld van voor, van die sy of van bo is.

Figure 4

b) Kom ons oefen eers om ‘n ortografiese tekening te maak.

Onthou:

  • Doen dit op geruite papier.
  • Sorg dat die lengte, breedte en hoogte van die figuur aangedui word.
    Figure 5
    Figure 5 (Picture 5.png)
  • Begin met die voor-aansig wat altyd in die linkerkantse boonste hoek geteken word.
    Figure 6
    Figure 6 (Picture 6.png)
  • Die bo-aansig word daarna in die linkerkantse onderste hoek geteken (verleng die vertikale sye van die voor-aansig).
    Figure 7
    Figure 7 (Picture 7.png)
  • Die sy-aansig (van regs) word altyd in die regterkantse boonste hoek geteken (verleng die horisontale sye van die vooraansig).
    Figure 8
    Figure 8 (Picture 8.png)
  • Elke spasie op die asse stel een cm voor. Begin eers by die eerste merkie.
  • Halveer die oorblywende ruimte skuins oor die vooraansig met ‘n 45°-diagonale lyn. Gebruik hierdie lyn om die lengtes vanaf die bo-aansig na die sy-aansig oor te dra.
  • Voltooi al drie aansigte en verskaf die nodige byskrifte.
  • Maak nou ook nog 2D-tekeninge van die volgende 3D-vorms. Dui eers die aansigte by elke vorm aan.

OPDRAG 2:

Probeer om rofweg ‘n skuinsaansigtekening van jou houertjie op geruite papier te maak. Dui die afmetings (lengte, breedte en hoogte) aan.

Table 2
         
  LU/AS 1.12      
         
Figure 15
Figure 15 (Picture 15.png)

Probeer om die houertjie ortografies vanuit die aansigte voor te stel (geruite papier).
