Description:
In-order to model the high rise, which has unique shapes of
walls at alternating floors, the mass model is first created with the required
parameters. The parameters are related to each other so that the entire mass is
controlled by these parameters. The footprint of the building that is modelled
is as shown in figure 1.

Modelling:
The parameters are pretty simple for this building. Before
the boundaries are drawn, the parameters should be aligned to the references
lines and not the boundary surfaces. If aligned to the boundary surfaces,
constraint errors are going to pop up. Revit is not convenient to use when many
errors of such kind commonly arise.

Lines for the building
The smaller square at the 2nd level is drawn to
create a void from the 20th floor to the 25th floor on
the shorter leg of the L-shaped building. The final Mass Model is as shown
below in Figure 3.

The various parameters assigned and their relation to other
parameters are as follows:

Changing the above parameters we get the following

My goal for this project was to create curved walls for
every floor, but with alternating frequencies. Since the curve and frequencies
come into play, a custom made curtain panel is made using the formulae of a
Sine Curve. That panel is fitted into the divided surface of a wall in the mass
model and the parameters are assigned to it.

Up-to this point, all the models are made in the family
files. Now this family is loaded into a new project, where the model is further
worked on, where a site, walls, floors, roof, rooms, furniture etc., are placed
in the building. With the mass form as guidance walls and floors are created
and then the mass for can be turned off as per settings.

Critics on
Revit Modelling Application:
Without coding,
using on modeling tools of Revit becomes hectic, for example, custom and unique
color for a 100 panels. This becomes too cumbersome if manually done. And also
as stated before, Revit takes the constraints in modelling very seriously. If
not parameterized correctly, errors pop up very easily. So the user has to have
thought over all the necessary details.
