Project 1: Modelling of an Architectural Design / Form of Swimming Pool (Boolean & Inset)

I'm doing a form of swimming pool at Underground Floor.

Create a shape of swimming pool in AutoCAD and Extrude it in 3ds Max.

Move the form of swimming pool at a position where it could intersect with the floor slab.

Click on the form of swimming pool > Compound Objects > Boolean.

Pick Operand B > Pick the Floor Slab.

Operation > Subtraction (B-A).

Click the second form of swimming pool.
Edit Poly > Polygon > Insert Vertex > Inset > Type value (The value is the edge dimension of swimming pool).

Delete the inner part to create the empty part of swimming pool.
