I-OpenSCAD wuhlelo lwesofthiwe yamahhala lokudala izinto eziqinile ze-3D ezisizwa ngekhompiyutha (CAD). Kuyimodeli esekelwe kumbhalo kuphela esebenzisa ulimi lwayo lokuchaza; izingxenye zingabukwa kuqala, kodwa azikwazi ukuguqulwa ngokuhlanganyela ngegundane ekubukeni kwe-3D. Umbhalo we-OpenSCAD ucacisa ama-primitives ejiyomethri (okufana nama-sphere, amabhokisi, amasilinda, njll.) futhi uchaza ukuthi alungiswa futhi ahlanganiswe kanjani (isibonelo ngokuphambana komgwaqo, umehluko, inhlanganisela yemvilophu kanye nezibalo ze-Minkowski) ukuze zinikeze imodeli ye-3D. Ngakho-ke, uhlelo lwenza ijometri eqinile eyakhayo (CSG). I-OpenSCAD iyatholakala ngeWindows, Linux kanye ne-macOS.
