Kuvaka Zvinhu Ne AutoCAD - Chikamu 2
6.2 Splines
Splines ndiwo maitiro e-smooth curves anogadzirwa maererano nenzira iyo yakasarudzwa kududzira pfungwa dzinoratidzwa pahwindo.
Mu Autocad, rwonzi rwunotsanangurwa se "isina-yunifomu rune Bezier-spline curve" (NURBS), zvinoreva kuti guva harina kuumbwa neyemamiriro ezvinhu arcs, kana elliptical arcs. Iyo yakapetwa yakagadzirirwa iyo, hongu, inotibatsira kugadzira zvikamu zvekugadzira nema curves anopunyuka geometry yezvinhu zvakareruka. Seizvo muverengi anga afungidzira, mazhinji mafomu emotokari, semuenzaniso, pamwe neayo emazhinji ergonomic zvishandiso, zvinoda kudhirowa kwerudzi urwu rwemavara. Pane nzira mbiri dzekuvaka denderedzwa: ine setpoints kana ine control vertices.
Tsambanhare ine zvikamu zvakaiswa zvinopfuura nepfungwa dzinoratidzwa pachiratidziri. Nekudaro, iyo ye "Knots" sarudzo inokubvumira kusarudza nzira dzakasiyana dzemasvomhu ekuparadzanisa paramende, iyo inogona kuburitsa zvishoma yakashomeka mativi emakero akafanana.
Nekudaro, iyo "toLerance" sarudzo yemirairo inosarudza kunyatsoenderana neiyo iyo curve inoenderana neiyo mavara. Iko kukosha kwekugadzirisa yakaenzana ne zero kunozoita kuti iyo curve ipfuure zvakanyatsooma kuburikidza neaya mapoinzi, chero kukosha kunze kwekuti "icha" kufambisa iyo curve kubva pamapepa. Ngatitarisei kugadzirwa kwevaravara rine setet point asi nekusiyana kwakasiyana.
Iwe unogona kunge watoona kuti pakutanga kwekuraira isu tine "Nzira" sarudzo, iyo inotibvumidza kuti tishandure kune yechipiri nzira yekugadzira splines, ndiko kuti, kushandisa control vertices, kunyangwe isu tinokwanisa kusarudza nzira iyi zvakananga kubva kubhatani rayo mune Ribhoni
Splines yakagadzirwa nemitemo yekudzivirira inogadzirwa kuburikidza nehutu, pakati pavo, hunobudisa mitsara yemagariro epa polygon iyo inotarisa maitiro epepline. Kubudirira kweiyo nzira ndeyokuti izvi zvinyorwa zvinopa hukuru hwakakura pamusoro pekugadzirisa spline, kunyange zvazvo pakugadzirisa zvinogona kushandura tsananguro yezvigadziro zvekutarisa maziso uye pamwe chete.
Kunyange zvazvo shanduro yepline iri nyaya yechitsauko che18, tinogona kutaura izvozvo nokusarudza spline, tinogona kushandisa gumbo rayo katatu kuti tishandure maratidziro ayo akaenzana kana kutonga vertices. Tinogonawo kuwedzera zvimwe, kuchinja kana kuvanatsa.
6.3 Clouds
Iko rekudzokorora gore harisi chinhu chakavharidzirwa nepo polyline yakagadzirwa nema arcs ane chinangwa chekujekesa zvikamu zvekudhirowa kwaunoda kutsvaga nokukurumidza uye pasina kukosha zvakanyanya kuve kwechokwadi kwezvikamu zvayo.
Pakati ayo nzira unogona kushandura pakureba arcs mugore, izvo achawedzera kana kuderera nhamba arcs vaifanira kusika izvozvo, tinogonawo exchange chinhu akadai polyline kana ellipse ari dzokororo gore uye kunyange kuchinja maitiro ako , iyo inogona kugadzirisa mashizha ega imwe neimwe yeArc.
6.4 Washers
Vakashers ndeye tsanangudzo zvidimbu zvidimbu zvesimbi zvakasara mukati. MuCococad vanotarisa semhete yakasvibirira, kunyange zvazvo chaizvoizvo inoumbwa nemaviri emasvikiti ane uwandu hunotsanangurwa nehumukati hwepamusoro uye humwe hupamhi. Kana hupamhi hwemukati huchienzanisa zero, zvino izvo zvatichaona irukwa rakazara. Nokudaro, iyo imwe chinhu chinogadziriswa chinangwa chayo ndechokuita kuti zvisikwa zvive nyore nehurongwa, zvichipiwa nguva inogona kushandiswa.
