ARCH 653 PROJECT 2

HELIX BRIDGE

Concept

In project 2, I choose to build a helix bridge. For the complex geometric shape, it is hard to build the bracing elements between the very curves, so I use Dynamo to solve this kind of challenge.

After watching tutorial videos for the Dynamo plugin for Revit, I decided to create the elements using the adaptive component and apply them as arrays in the family.

Step 1:Creating the basic shape object

The first step was to create a basic shape with two cylinders tangent together at their bottom points. I started with a mass family and implemented cylinders reference geometry parameters within a radius and the distance between the two faces. Then I divided the surface of this two cylinders.Need to mention, after dividing, I changed the points on the surface into nodes so that I could use these reference points to locate my helix.

Then I begin to add my structural curves on the surfaces of this two cylinders.

Step 2:Creating the adaptive mass family

The second step is to build the bracing elements between these curves and build the structural volume using Dynamo. The basic strategy is to create an array of these elements to suit the changing distance between the certain curves. In order to get this purpose, I use Generic adaptive mass model to create the basic bracing model.

Make the two end points into adaptive points. And use spline between two points to connect the two points.

Creating the volume of the bracing elements.

Step 3:Using Dynamo to add the bracing elements family

After we open Dynamo, the first thing is to select the curve as the target, and remember if you want to choose a line, it also uses the command select curve. Then I choose a number slider which can determine the number of the elements. After this I need transfer the elements end points into XYZs so that the system can make a list of the XYZs of these points.

When I finish the above, the most important process is to combine these XYZs together, fortunately there is a combine in Dynamo I can use to make this connection. We can notice that there is a gray bar there, and this bar is so important for it is used to define these XYZs' combination type----List.

After this, use the select family type and find the family 2 you did before(loaded into this family already so that you can find in the bar).

ARCH 653 Project 1

Parametric Modeling Practising in Revit---Al Zorah Pavilion

For project one, I choose the Al Zorah pavilion which is a landmark in Ajman, it is the first project to be implemented on site, as part of the city’s redevelopment. The structure is a 4 500 Msq multifunctional center dedicated to Administration, Culture and Entertainment overlooking the mangrove of Ajman.

The pavilion is designed with a very sensitive approach to the site, in symbiosis with the landscape. It is conceived as a simple geometric form standing in the desert as a landscape within another. It rests under a canopy, a folded roof reminiscent of the existing topographical strata leading down to the water.

After I did analysis on the project, I found the volume of this building is not regular, so the mass model I should concentrate on the its shape and the roof  is all clad with zinc shingles protecting the pavilion from strong sunlight and simultaneously blocking the noise from the nearby highway, which is also a point I need to do in the parametric modeling.

Part one: Conceptual Mass Modeling

Plane of the Pavilion

East elevation of the Pavilion

After I found the plane and elevation of the project, I began to set up the reference plans in the mass model.And made the volume by using the solid forms.

Beginning creating the mass volume

Then I used the create void form to cut the whole mass into pieces and made them separate.

Final mass model

Parameter values were added to the conceptual mass so that I could adjust the roof and the curtain wall of the main mass body.

Part two: Custom the curtain panel and roof panel

Then I began to work on the wall panel and roof panel and add the parameter to control the added panels.  In the mass model, I divided the surface into rectangular and rhomboid unit. After that I created the new family of the curtain panel and reloaded them into the family.

Part three: the Revit project

After the mass model was finished, I reloaded it into a project and placed on a site with a simple environment. Walls and roofs and floors were added to the model.
