OpenSCAD yog software tsim cov qauv 3D CAD. Nws yog dawb software thiab muaj nyob rau Linux/UNIX, Windows thiab Mac OS X. Tsis zoo li feem ntau dawb software rau tsim 3D qauv (xws li Blender) nws tsis tsom rau kev kos duab ntawm 3D qauv tab sis hloov ntawm CAD yam. Yog li nws yuav yog daim ntawv thov uas koj tab tom nrhiav thaum koj tab tom npaj tsim 3D qauv ntawm lub tshuab qhov chaw tab sis zoo nkauj tseeb tsis yog qhov koj tab tom nrhiav thaum koj xav paub ntau dua los tsim cov yeeb yaj kiab hauv computer.

OpenSCAD tsis yog tus qauv sib tham sib tham. Hloov chaw nws yog ib yam dab tsi zoo li 3D-compiler uas nyeem hauv cov ntawv sau uas piav txog cov khoom thiab ua rau 3D qauv los ntawm cov ntawv sau no. Qhov no muab rau koj (tus tsim qauv) kev tswj hwm tag nrho ntawm cov txheej txheem ua qauv thiab ua rau koj yooj yim hloov txhua kauj ruam hauv cov txheej txheem qauv lossis tsim cov qauv uas tau txiav txim siab los ntawm kev teeb tsa tsis tau.

OpenSCAD muab ob txoj hauv kev ua qauv tseem ceeb: Ua ntej muaj kev tsim khoom geometry (aka CSG) thiab thib ob yog extrusion ntawm 2D cov qauv. Autocad DXF cov ntaub ntawv tuaj yeem siv los ua cov ntaub ntawv pauv hloov pauv rau cov qauv 2D. Ntxiv rau 2D txoj hauv kev rau extrusion nws kuj tseem tuaj yeem nyeem cov qauv tsim los ntawm DXF cov ntaub ntawv. Dhau li ntawm DXF cov ntaub ntawv OpenSCAD tuaj yeem nyeem thiab tsim 3D qauv hauv STL thiab OFF cov ntaub ntawv tawm tswv yim.
