Stage 1: Creating Forms with Revit Conceptual Masses (for 2 or more units)

Part 1 - Test One of the Example Conceptual Mass Forms by Flexing One Input

For the initial testing phase, I utilized the Rectangular Mass example.

Parameters Flexed: I tested varying combinations of the building's base dimensions (width and depth) and overall height, ensuring the gross floor area remained within the target range while respecting the 230m height limit.
Design Observations: Flexing these simple parameters provided a strong baseline for understanding how dimensional changes linearly affect total gross volume and surface area.

Part 2 - Create Your Own Conceptual Mass Form and Test It

For my original conceptual form, I developed an Elliptical Mass to explore a softer, more aerodynamic profile for the Dubai skyline.

Parameters Flexed: This form was built with independent, dynamic controls, including:

Stage 2: Creating Forms with Dynamo or Grasshopper Geometry (for 3 or more units)

My initial design intent in Dynamo was to create a Teardrop/Airfoil profile.

Initial Logic: Theoretically, this shape is highly optimized for the Dubai site. The aerodynamic profile minimizes wind resistance (a major structural concern for high-rises) and efficiently reduces the building envelope surface area relative to the internal volume.
The Pivot: During the modeling process, the "sharp" trailing edge of the airfoil created geometric singularities. When Dynamo attempted to loft the surfaces across these sharp points, it resulted in self-intersections and surface errors.
The Solution: To resolve this while maintaining the core design philosophy, I smoothed the profile to create an Egg-Shaped Tower. This maintained the aerodynamic benefits and organic aesthetic of the teardrop while ensuring the Dynamo logic could reliably loft the profiles into a clean, manifold geometry for accurate volume and surface area evaluations.
