Ko e OpenSCAD ko ha polokalama fakakomipiuta ia ki hono faʻu ʻo ha kau ta sipinga fefeka 3H. Ko ha polokalama fakakomipiuta taʻetotongi ia pea ʻoku lava ke maʻu atu ia ki he lines ili x/UNIX, Windows mo e Mac OS X. ʻOku ʻikai tatau ia mo e polokalama fakakomipiuta taʻetotongi taha ki hono faʻu ʻo ha kau ta sipinga 3H (hange ko e blender) ʻoku ʻikai tokanga ia ki he ngaahi tafaʻaki fakaʻaati ʻo e 3H modelling ka ʻi he ngaahi tafaʻaki ʻo e d. Ko ia ai, mahalo ko e tohi kole ʻoku ke fekumi ki ai ʻi he taimi ʻoku ke palani ai ke faʻu ha ngaahi sipinga 3H ʻo e ngaahi kongokonga ʻo e misini ka ʻoku ʻikai ko e meʻa ia ʻoku ke fekumi ki ai ʻi he taimi ʻoku ke tokanga ange ai ki hono faʻu ʻo e ngaahi faiva fakakomipiuta.

ʻOku ʻikai ko ha modeller fengaueʻaki ʻa OpenSCAD. Ka ko ha meʻa ia ʻoku hange ha 3H-compiler ʻoku lau ʻi ha faile script ʻoku ne fakamatalaʻi ʻa e meʻa ko ia pea ʻoku ne ʻomi ʻa e sipinga 3H mei he faile fakamatala ko ʻeni. ʻOku ʻoatu ʻe he meʻa ni kiate koe (ko e tokotaha Designer) ʻa e mapuleʻi kakato ʻo e founga modelling pea ʻai ke faingofua hoʻo liliu ha faʻahinga sitepu ʻi he founga modelling pe faʻu ha ngaahi faʻufaʻu ʻoku fakaʻuhingaʻi ʻe he ngaahi fakangatangata configurable.

ʻOku ʻomi ʻe he OpenSCAD ha tefitoʻi founga modelling ʻe ua: ʻuluaki ʻoku ʻi ai ha he fika fefeka (aka CSG) pea ko hono ua ʻoku extrusion ʻa e ngaahi fokotuʻutuʻu 2D. ʻE lava ke fakaʻaongaʻi ʻa e ngaahi faile Autocad DXF ko e founga fakafetongi ʻo e fakamatala ki he ngaahi fokotuʻutuʻu 2D pehee. Makehe mei he ngaahi hala 2D ki he extrusion ʻoku toe malava pe foki ke lau ʻa e ngaahi fakangatangata mei he ngaahi faile DXF. Makehe mei he ngaahi faile DXF OpenSCAD ʻe lava ke lau mo faʻu ha kau ta sipinga 3H ʻi he ngaahi founga ʻo e STL mo e faile.
