Cia peb rov qab mus rau "Kos duab tsis" teeb meem lub thawv. Qhov "Polar tracking" tab tso cai rau koj los kho tus yam ntxwv ntawm tib lub npe. "Daj mus txog qhovtwg", zoo li "Kev qhia siv ntsuas", tsim cov kab muaj kab, tab sis tsuas yog thaum tus cursor hla lub kaum sab xis uas tau hais tseg, lossis nce ntxiv ntawm nws, los ntawm cov keeb kwm kev ua haujlwm (X = 0, Y = 0), lossis taw tes kawg taw qhia.

Nrog rau "Kev Siv Khoom Siv" thiab "Kev Taug Qab Xyuas Nres" lub tshuab ua kom tiav, Autocad qhia pom kab ntawm cov ces kaum uas teev hauv lub thawv. Hauv qhov no, tau muab teeb tsa ua yeeb yaj kiab dhau los, los ntawm qhov kawg tau siv. Yog tias peb xav kom nws qhia kab kab ntawm cov ces kaum sib txawv, tom qab ntawd peb tuaj yeem ntxiv lawv rau hauv cov kab ntawv hauv lub thawv.

Nyob rau hauv tib txoj kev raws li "Kev txheeb xyuas cov ntsiab lus", "Kev Nthuav Tawm Tawg Nres" kuj tso cai rau los qhia ntau dua ib qho kev siv rau cov khoom thiab yuav qhia cov kev sib tshuam ntawm sab hauv polar nrhiav cov kab uas tau los ntawm lawv. Hauv lwm lo lus, nrog tus yam ntxwv no, thaum kos duab ib yam khoom tshiab, peb tuaj yeem taw tes rau qhov siv rau cov khoom ("kawg taw tes", "quadrant", "chaw nruab nrab", thiab lwm yam) thiab cov duab txiav ntawm lub kaum muag yuav tawm; Tom qab ntawd peb taw mus rau lwm qhov kev siv ntawm lwm yam khoom, nrog uas peb yuav pom cov kev sib tshuam sib txuas uas tshwm sim los ntawm kev taug qab ntawm ob lub ntsiab lus.

Yog li, peb yuav hais txog qhov tseeb tias 3 cov cuab yeej sib koom ua ke no, "Kev Ntsuas Khoom Siv", "Taug Qab ..." thiab "Teem Kev Nres", tso cai rau peb los tsim qhov kev ntsuas ntawm cov khoom tshiab sai heev los ntawm qhov uas twb tau kos thiab tsis muaj kev cuam tshuam ntawm precision.
