O le FreeCAD o se fa'ata'ita'iga fa'ata'ita'iga 3D fa'akomepiuta (CAD) fa'ata'ita'i fa'ata'ita'iga fa'ata'ita'i fa'ata'oto ma se polokalame fa'ata'ita'i fa'amatalaga faufale (BIM) fa'atasi ai ma le lagolago fa'agata (FEM). E fa'amoemoe mo le fa'ainisinia fa'ainisinia o oloa fa'ainisinia ae fa'alautele fo'i i le lautele lautele o fa'aoga fa'ainisinia, e pei o le tusiata fale po'o le inisinia eletise. FreeCAD e leai se totogi ma tatala-puna, i lalo ole LGPL-2.0-poʻo-mulimuli laisene, ma avanoa mo Linux, macOS, ma Windows operating system. E mafai e tagata faʻaoga ona faʻalauteleina le faʻaogaina o le polokalama e faʻaaoga ai le Python programming language.
