CHITSAUKO 12: KUCHENGA KWEPARAMETRIC

Kana isu tikashandisa chirevo chezvinogumisa zvinhu, kana pakati, semuenzaniso, zvatiri kunyatso kuita kuri kumanikidza chinhu chitsva kugovana poindi yejometri nechimwe chinhu chakatodhindwa. Kana tikashandisa rekuti “Parallel” kana kuti “Perpendicular”, chinhu chimwe chete chinoitika, tiri kumanikidza gadziriso yejometri yechinhu chitsva zvine chekuita nemumwe, saka kana isingaenzane kana kusarudzika, zvinoenderana nemhosva uye pakati pezvimwe sarudzo, chinhu chitsva ichi hachigone kusikwa
"Parametric Kudzivirira" kunogona kuoneka sekuwedzera kwepfungwa imwechete iyo inokurudzira kuturikira zvinhu. Musiyano ndewekuti iyo yakarongedzwa geometric inoramba iri chinodikanwa kuti chinhu chitsva chinofanira kusangana zvachose, kana kuti panzvimbo pacho, sechirambidzo.
Nenzira iyi, kana tikagadzira rwonzi sezvinoenderana nechimwe, saka zvisinei kuti tinoshandura sei imwe mutsara, chinhu chinoregererwa chinofanira kuramba chichienzaniswa.
Zviri pachena, kushanda kunoita chakarambidzwa musoro kana kuchinja chinhu. Kureva, pasina kurambidzwa tinogona kuita shanduko chero kune mifananidzo, asi ivo zviripo, zvinobvira kuchinja shoma. Kana tiri chekucheresa Autocad kumbova chinhu chinoda havashanduki, zvino haatombotauri musoro kushandisa zvakadaro parametric mufanidzo chengeto. Kana, Ukuwo, zviri kuita mufananidzo chivako kana zvokuimba chikamu ane kwokupedzisira shape're vachiri achitarira, ipapo parametric constraints zvinobatsira nokuti inotipa kuchitoro wakaiswa ukama avo pakati zvinhu, kana kukura, dzedu kugadzira anofanira kusangana.

Nemamwe mashoko, kuti parametric mitemo guru chishandiswa zvakagadzirwa mabasa, zvichiita kuti kugadzira avo okunze ane kukura kana geometrical ukama inofanira kuramba.

Kune marudzi maviri emiganhu yepametric: Geometric neCota. Chokutanga wainyatsotaura geometric constraints zvinhu (perpendicular, yakafanana, kutwasuka, etc.), ukuwo ndeiya yakaita constraints akaisa divi (marefu, pamakona uye radii ine yakananga ukoshi). Semuenzaniso, mutsetse unofanirwa kugara uine michina ye100 kana mitsetse miviri inofanira kugara ichigadzira ngero ye 47 ° digri. Uyewo, akasungwa constraints kungaratidzwa sezvo equations, saka kuti kwokupedzisira divi ane chinhu chinobva tsika (shanduka kana kuramba) kuti mukana wokuti vanhu vanga rinoumbwa.

Sezvo tichadzidza fora zvishandiso zvinhu kubva chitsauko 16, ona pano sei rokusika, maonero uye kutarisira parametric constraints, asi tichadzoka kwavari kuti chitsauko.

12.1 Geometric zvinetso

Sezvatangobva kutaurwa, mitemo ye geometric inogadzira urongwa hwe geometric uye hukama hwezvinhu nekuremekedza vamwe. Ngationei mumwe nomumwe:

12.1.1 Matching

Ichi chiremera chinokonzera chinhu chechipiri chakasarudzwa kuti chibatane mune zvimwe zvemashoko aro nechimwe chinhu chekutanga. Sezvatinoendesa chinhu chisarudzo, Autocad inoratidzira pfungwa dzakasiyana dzakasiyana dze geometry dzatinokwanisa kufanana nechinangwa cheimwe chinhu.
