Revit Modeling:
1. Mass modeling: Conceptual mass.rft
2. Pattern modeling: Curtain Panel Pattern Based.rft

The mass modeling includes the following steps
1.1 Creating the required reference plans based on the floor plans 
1.2. Drawing plan outlines 
1.3. Defining parameters
1.4. Dimension constraint (length, width, height, angle) 
1.5. Assign dimensions to parameters



    Create mass through extrusion and boolean
    Assigning the extrusion height to the height parameters. 


1.6. Divide surfaces and select the required pattern. In this case "Triangle(flat) is selected. 


Note: Sets of parameters are defined for the pattern. 
The facade pattern is a hexagon pattern consists of 6 equilateral triangles in 3 layers of glazing, shading, and structure.

One equilateral triangle is modeled as a module for the facade. The U-Grid and V-Grid parameters are defined to make the original triangle pattern equilateral based on the bisector equation in an equilateral triangle. The same numbers are then used for the pattern.rft file.

2. Pattern modeling: Curtain Panel Pattern Based.rft

2.1. Using the same number of U_grid and V_grid for vertical spacing and horizontal spacing accordingly.
2.2. Create an instance base parameter the same as the Base in the mass model and check "Reporting Parameter". The values of the Base parameter in both models should match.


2.2 Creating the glazing layer 
2.3 Creating the shading layer




2.4 Creating the shading layer

Curtain panel parameters:
Different parameters are set to make the pattern module dynamic, including the opening and closing scale of the shadings, the depth of the movement of the shadings, the distance of the shading from the glazing and the distance of the structure from the shadings. 
the material parameters are also defined as a placeholder and the corresponding masses are assigned to. These parameters will be assigned again to type parameter in the mass model in order to pass them at the project level.

After the modeling is finished, the pattern is loaded into the mass model.

Creating material type parameter and assign the patterns' materials to them so they could be passed to the project level.

A simple glazing pattern has also been loaded to the mass model for the fist floor facade pattern.
Finally, the mass model is loaded into an architectural project Revit file (.rvt)

Other steps:
- Transfering the mass model to a project model with floors (5 levels), Roof and walls.
- Assign the materials
- Drawing the plan floor layout and place furniture
- drawing the topography and site plan
