TSHOOJ 6: TSIS TXAUS SIAB

Peb hu ua "cov khoom sib txuas" cov khoom uas peb tuaj yeem kos hauv Autocad tab sis qhov ntawd nyuaj dua li cov khoom siv yooj yim uas tau soj ntsuam hauv ntu ntawm tshooj dhau los. Qhov tseeb, cov no yog cov khoom siv uas, qee kis, tuaj yeem txhais tau ua kev sib txuam ntawm cov khoom yooj yim, txij li lawv cov duab geometry yog kev sib txuas ntawm cov khoom ntawm lawv geometry. Hauv lwmyam xwm txheej, xws li splines, cov no yog khoom nrog lawv tus kheej tsis dhau. Nyob rau hauv txhua rooj plaub, cov hom ntawm cov khoom uas peb tshuaj xyuas ntawm no (polylines, splines, propellers, txuas, huab, cheeb tsam thiab npog), tawg txhua yam tsis muaj kev txwv rau kev tsim cov duab uas cov khoom yooj yim muaj.
