Hi @kuladeep561

1-first you need to cluster the point to group (all the point have the same plane Ex: slab and wall ). You can use RANSAC.
2- for each group draw outer line around the outside points by ignoring any points that would fall inside.
Alpha Shape proplem (Draw outer line around the outside point Cloud at the same plane by ignoring any points that would fall inside.)
