Understanding Dimensioning in Technical Drawing

Dimensioning in technical drawing is essential for accurately portraying the measurements of an object. It involves using specific elements such as dimension lines, dimension numbers, and arrows to indicate important dimensions for production. The process of dimensioning ensures that the object can be manufactured accurately based on the provided measurements. Different elements like auxiliary lines, dimension numbers, and dimension arrows play a crucial role in dimensioning, helping to communicate the necessary information effectively and independently of the drawing's precision.

  1. KOTIRANJE (knjiga strana 14-15)

  2. Kotiranje • Da bismo mogli da napravimo nacrtani predmet, na crtežu moraju biti istaknute sve mjere važne za njegovu izradu. • Informacije o mjerama predmeta upisuje se u brojčanom obliku i tako njeno prenošenje postaje nezavisno o tačnosti crtanja. • Djelovi crteža koji sadrže informacije o mjerama predmeta nazivaju se kotama.

  3. Elementi kotiranja su: POMOĆNA KOTNA LINIJA KOTNI BROJ KOTNA STRELICA GLAVNA KOTNA LINIJA

  4. Kotiranje • Za kotiranje se koriste pune tanke linije i povlače se paralelno sa ivicama predmeta. • Kotni brojevi ispisuju se iznad kotne linije, na sredini njene dužine. • Brojčane vrijednosti izražene su u milimetrima, ali se mm ne upisuje.

  5. Kotiranje Kada se kotiraju djelovi cilindričnog oblika, ispred kotnog broja upisuje se oznaka Ø (fi).
