OpenSCAD ndi pulogalamu yopangira mitundu yolimba ya 3D CAD. Ndi pulogalamu yaulere komanso yopezeka kwa Linux / UNIX, Windows ndi Mac OS X. Mosiyana ndi mapulogalamu ambiri aulere opangira zitsanzo za 3D (monga Blender) sichiyang'ana mbali za luso la 3D modeling koma m'malo mwa CAD. Chifukwa chake itha kukhala pulogalamu yomwe mukuyang'ana mukamakonzekera kupanga mitundu ya 3D yamakina koma zowona kuti sizomwe mukuyang'ana mukakhala ndi chidwi chopanga makanema apakompyuta.

OpenSCAD si njira yolumikizirana. M'malo mwake ndi chinthu chofanana ndi 3D-compiler chomwe chimawerengedwa mu fayilo ya script yomwe imalongosola chinthucho ndikupereka chitsanzo cha 3D kuchokera pa fayiloyi. Izi zimakupatsirani (wopanga) kuwongolera kwathunthu pamayendedwe akutsanzira ndikukuthandizani kuti musinthe mosavuta gawo lililonse lachitsanzo kapena kupanga mapangidwe omwe amatanthauzidwa ndi magawo osinthika.

OpenSCAD imapereka njira ziwiri zazikulu zowonetsera: Choyamba pali geometry yolimba (yotchedwa CSG) ndipo yachiwiri pali kutulutsa kwa 2D. Mafayilo a Autocad DXF atha kugwiritsidwa ntchito ngati njira yosinthira deta pamawunila a 2D. Kuphatikiza pa njira za 2D za extrusion ndizothekanso kuwerenga magawo apangidwe kuchokera kumafayilo a DXF. Kupatula mafayilo a DXF OpenSCAD imatha kuwerenga ndikupanga mitundu ya 3D mumitundu yamafayilo a STL ndi OFF.
