I-OpenSCAD yisoftware yokwenza imifuziselo eqinileyo ye-3D CAD. I-software yamahhala kwaye ifumaneka kwi-Linux / UNIX, iWindows kunye ne-Mac OS X. Ngokungafaniyo neyona nto ininzi yesofthiwe yokudala imodeli ye-3D (efana ne-Blender) ayigxininisi kwiinkalo zobugcisa be-3D modeling kodwa kunoko kwiinkalo ze-CAD. Ke isenokuba sisicelo osifunayo xa uceba ukwenza iimodeli ze-3D zamalungu omatshini kodwa ngokuqinisekileyo ayisiyiyo le nto uyikhangelayo xa unomdla wokwenza iimuvi zekhompyuter.

I-OpenSCAD ayiyomodeli esebenzayo. Endaweni yoko yinto efana ne-3D-compiler efunda kwifayile yescript echaza into kwaye inike imodeli ye-3D kule fayile yeskripthi. Oku kukunika (umyili) ulawulo olupheleleyo lwenkqubo yokwenza umfuziselo kwaye kukwenza ukuba utshintshe ngokulula naliphi na inyathelo kwinkqubo yomzekelo okanye wenze uyilo oluchazwa ziiparamitha eziqwalaselweyo.

I-OpenSCAD ibonelela ngeendlela ezimbini eziphambili zokubonisa: Okokuqala kukho ijometri eyomeleleyo eyakhayo (eyaziwa ngokuba yi-CSG) kwaye okwesibini kukho ulwandlalo lwe-2D. Iifayile ze-Autocad ze-DXF zingasetyenziswa njengefomathi yokutshintshiselana kwedatha kwiinkcazo ezinjalo ze-2D. Ukongeza kwiindlela ze-2D ze-extrusion kuyenzeka ukuba ufunde iiparamitha zoyilo kwiifayile zeDXF. Ngaphandle kweefayile zeDXF I-OpenSCAD inokufunda kwaye yenze imifuziselo ye-3D kwi-STL kunye neefomati zefayile ze-OFF.
