In　recent　years,　with　the　development　of　digital　information　technology　and　the　combination　of　architectural　design　field　and　other　fields,　architectural　design　methods　and　processes　are　constantly　changing,　and　architectural　generative　design　methods　appear.　Building　generation　design　is　a　self-generated　design　of　building　space　units　based　on　different　complex　models　and　algorithm　logic.　Among　them,　the　main　function　of　computers　is　to　calculate　and　screen,　and　to　visualize　complex　and　abstract　problems.　By　designing　related　programs　and　algorithms,　the　optimal　solution　is　sought　in　different　constraints.　As　a　new　social　group,　youth　groups　have　many　inconveniences　at　the　beginning　of　community　life,　and　we　lack　of　community　architecture　research　for　this　group.　This　paper　puts　the　Transition　Design　theory　into　a　conceptual　youth　community　architecture　scheme,　and　tries　to　solve　the　problems　of　optimal　path,　architectural　modeling　and　spatial　layout　in　the　scheme　by　combining　theory　with　digitization,　so　as　to　provide　thinking　and　reference　for　the　design　of　digital　youth　community　architecture.　©　2023,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG.
