Izithiyo ze-geometric ze-12.1

Njengoba sesanda kuphawula, izithiyo ze-geometri zakha ukuhlelwa nokuhlobana kwezinto ze-geometric ngokuphathelene nabanye. Ake sibone ngamunye:

Ukufana kwe-12.1.1

Lo mkhawulo uphoqa into yesibili ekhethiwe ukuba ihambisane namanye amaphuzu alo ngephuzu lento yokuqala. Njengoba sithutha umkhethi wezinto, i-Autocad igcizelela amaphuzu ahlukene we geometri esingafanelana nephuzu lenye into.

I-12.1.2 Collinear

Ithuthela emgqeni wesibili ekhethiwe ukuba ibe collinear ngokuphathelene nomugqa wokuqala.

I-12.1.3 Concentric

Imibuthano yamabutho, ama-arcs nama-ellipses ukwabelana phakathi nendawo yezinto zokuqala ezikhethiwe.

I-12.1.4 Fixed

Setha indawo yephuzu njengoba lihleliwe, lonke i-geometry yento ingashintshwa noma ifakwe.

I-12.1.5 Parallel

Iguqula isimo sezinto sesibili okufanele sibekwe endaweni efanayo ngokuphathelene nento yokuqala ekhethiwe. Kubuye kuchazwe ngomqondo wokuthi umugqa kufanele ugcine i-angle efanayo ne-reference object. Uma ingxenye ye-polyline ikhethiwe, yiyo ezoshintsha, kodwa hhayi zonke izingxenye ze-polyline.

I-12.1.6 Perpendicular

Iphoqelela into yesibili ukuba ibe yi-perpendicular kuya kokuqala. Okusho ukuthi, ukwakha i-angle ye-90 degrees nayo, nakuba kokubili izinto akudingeki ukuthi zithinte. Uma into yesibili i-polyline, ingxenye eyodwa ekhethiwe iyashintsha.

I-12.1.7 ephelele futhi ebonakalayo

Le mikhawulo ibeka umugqa kunoma yisiphi isikhundla sayo se-orthogonal. Noma kunjalo, futhi banenketho ebizwa ngokuthi "Amaphoyinti amabili", esingachaza ngayo ukuthi yilawa maphuzu phakathi kwabo okumele aqhubeke e-orthogonal (ovundlile noma mpo, ngokuya ngesibambiso esikhethiwe) noma ngabe kungeyona into efanayo.

I-12.1.8 Tangency

Iqoqa izinto ezimbili ezizodlala ngokudla. Ngokusobala, enye yezinto ezimbili kufanele ibe ijika.

I-12.1.9 Iphunga

Iphoqa u-spline ukugcina ukuqhubeka kwekhava layo ngenye into.

I-12.1.10 Symmetry

Iphoqa into eyodwa ukuba ihlale ihambisana nomunye ngokuphathelene nento yesithathu ekhonza njenge-axis.

I-12.1.11 Yekulingana

Qhathanisa ubude bomugqa noma ingxenye ye-polyline ngokuphathelene nomunye umugqa noma ingxenye. Uma isetshenziselwa ezintweni ezigobile, njengembuthano nama-arcs, yini elinganayo ke yi-radii.
