Nrog phau ntawv tsom xam, qhov magnification tuaj yeem hloov mus tas li.
Ua kom tiav geometric ntsuas (ntau qhov ntsuas ntsuas rau cov ntsiab lus, kab, voj voog, arcs, duab plaub, zawj, ntsuas qhov tseeb txhim kho, thiab lwm yam).
Lub ntug tsis siv neeg nrhiav kev ua haujlwm ntawm cov duab thiab cov cuab yeej ntsuas cov duab muaj zog ua kom yooj yim rau txoj kev ntsuas thiab ua kom qhov ntsuas tau yooj yim dua thiab ua tau zoo dua.
Txhawb kev ntsuas muaj zog, yooj yim thiab ceev pixel tsim ua haujlwm, cov neeg siv tuaj yeem tsim cov ntsiab lus, kab, voj voog, arcs, duab plaub, zawj, qhov deb, kev sib tshuam, cov ces kaum, midpoints, midlines, verticals, parallels thiab widths los ntawm tsuas yog nyem rau ntawm cov duab.
