Umarnin polyline yana zana hanya mai haɗuwa na kowace adadin sassa madaidaici, dukkansu an ajiye su a matsayin abin LWPOLYLINE ɗaya. Domin dukkan hanyar abu ɗaya ne, zaɓen ta yana zaɓen kowace sashi lokaci ɗaya — motsa, juya, ko canza girman dukkan sifar a aiki ɗaya. Wannan shine babban bambanci daga layukan da aka sarƙa (Lines), inda kowace sashi abu ne mai zaman kansa.

Zana polyline

Rubuta polyline a tashar umarni ko danna maɓallin kayan aiki na Polyline.
Danna tabo na farko, ko rubuta X,Y ka danna Enter don daidaitawa madaidaiciya.
Danna kowace tabo mai biyowa — kowace dannawa yana ƙara sashi. Shigar da daidaitawa yana aiki a kowane mataki.
Danna Enter ko Space don kammalawa (yana bukatar aƙalla tabo 2 an sanya su).

Shigar da daidaitawa

Maimakon dannawa, rubuta madaidaicin matsayi ga kowace vertex:

Rubuta ƙimar X.
Danna , — tashar umarni tana nuna [X], [Y{cursor}].
Rubuta ƙimar Y.
Danna Enter don sanya vertex.

Kulle-kusurwa da tsawon sashi madaidaici

Irin dabarar snap na 45° kamar umarnin Line yana aiki tsakanin kowace tabo biyu masu jerawa. Yayin an kulle zuwa axis:

Maɓalli	Aiki
`0`–`9`, `.`	Ƙara lamba zuwa tsawon sashi
`-`	Tsawo mara kyau — yana juya shugabanci a kan axis (haruf na farko kaɗai)
`Backspace`	Share tsohon harafi na ƙarshe da aka rubuta
`Enter`	Sanya tabon na gaba a nisan da aka rubuta

Tsawon da aka tara na yanzu yana bayyana a tambayar tashar umarni a lokaci na rai. Dannawa yayin an kulle yana kwabewa a kan axis don haka sabuwar vertex tana sauka a kanta daidai.

Marfe na maɓallan madannai

Gyaran grip — vertices da tsakiyar sassa

Polyline da aka zaɓa yana nuna nauʼukan grip guda biyu:

Grip	Matsayi	Aikinsa
Vertex	A kowace tabo da aka sanya	Ja don sake matsayin wannan vertex; dukkan sassan da aka haɗa suna miƙewa don bi
Tsakiyar sashi	Tsakiyar kowace sashi	Ja don motsa ƙarshe biyun na wannan sashi tare, tare da kiyaye tsawo da kusurwar sashi

Grip na tsakiyar-sashi na musamman ne ga polylines — yana barka ka jawo sashi guda ɗaya a gefe ba tare da canza tsawonsa ba. A kan Line, grip na tsakiya yana kunna umarnin Move ga dukkan abin maimakon.

Babu grip guda ɗaya na “motsa dukkan polyline”. Don motsa dukkan hanya, yi amfani da umarnin Move.

Zaɓen polylines

DXF — Abin LWPOLYLINE

Ana ajiye polylines a matsayin abubuwan LWPOLYLINE a fayil ɗin DXF. Dukkan abubuwan — daidaitawar vertex, tutar rufewa, launi, layer, nauʼin layi, girman nauʼin layi, da kauri — suna juyawa ba tare da asara ba. Rectangles da aka zana da umarnin Rectangle suma ana ajiye su a matsayin LWPOLYLINE (rufe, vertices huɗu) kuma ba za a iya banbanta su a matakin DXF ba.
