In　the　form　language　of　architectural　design,　the　process　of　form　generation　and　the　source　of　form　are　completely　different　from　the　perspective　of　construction　and　vision.　The　two　traceability　for　form　are　opposite.　This　paper　attempts　to　quantify　and　analyze　the　process　in　a　creative　way　of　digital,　by　summarizing　the　relevant　digital　research　of　forms,　a　feasible　modular　sequence　is　proposed,　which　can　correspond　the　form　evaluation　based　on　construction　and　vision　in　architectural　design,　and　provide　an　actionable　way　by　digital　for　the　form　design　language.　©　The　Authors,　published　by　EDP　Sciences　2021.
