1) Using Dynamo creates a set of sinusoidal points and create a curve and create a surface out of the curve.

Aim: To create a set of sinusoidal points and create a curve and create a surface out of the curve

Introduction:

Dynamo is an open-source visual programming language for Revit, written by designers and construction professionals. It is a programming language that allows you to type lines of code; while also creating an algorithm that consists of nodes.

Procedure:

Step 1: Open Dynamo

Open New Architectural Template

Go to the Manage tab and click on Dynamo

In Dynamo Click on New

Step 2: Adding Blocks

Go to search and type code block

Click to Add Code Blocks

Add four code blocks

Adjust the blocks and rename them to Ampere, Repeat, Range

Set the values as shown in the above figure

Step 3: Adding Sin Operator

Add code block

And type in the following equation

""Ampere*Math.Sin(Repeat*range);""

Add Another 2 code block

Add following equation in code block

""10*Math.Cos(t)+Math.Cos(t)*W;""

""10*Math.Sin(t)+Math.Sin(t)*W;""

Connect all the blocks using node as following

Step 4: Add Points by coordinates

Go to search and type Point by Coordinates

Click to add

Add a code block and rename it as Z Value

Connect the points X, Y, Z ass shown below

Search Curve by control points

Click add and attach the point by coordinates

The result is as follows

Step 5: Add Another Layer

Select all the blocks and create a group by right click

Copy the group and paste it to remake the sin curve

Change the Z values to 10

Step 6: Creating Surface

Search List

Click to add

Connect both groups created to the list

Search Surface by Loft

Click to add

Connect the list created above to the Surface by loft

Result:

The final flowchart is as follows

The final model is as follow

2) Create a conceptual layout of the floor plan in dynamo. Using the tools available in dynamo link the lines to appropriate model elements in Revit by choosing the wall types and wall parameters. Make use of the sliders to slide through the height of the wall and the length of the wall.

Aim: To create a conceptual layout of the floor plan in dynamo

To create floor using wall types in dynamo. Tools used are Integer slider, code block, point by coordinates,

Procedure:

Step 1: Open Dynamo

Open New Revit Architectural project
Go to the Manage tab and open Dynamo

Step 2: Adding Blocks

Add 2 integer sliders and rename them X and Y

Add four point by coordinate blocks
Rename as Origin, P1, P2, P3

Connect as follows

Step 3: Adding Line

Search Line by start and endpoint as shown in figure

Connect to the points as follows

Step 4: Adding Wall type and its necessary components

Create a list of all the lines created using list block

From search bar

Add number slider for wall height
Add Levels block
Add wall type block

Search Wall by curve and height and add to the workspace

Connect as follows to the components created above

Result:

The final Flow chart is as follows

The wall layout is as follows

3) Create an array of model elements in Revit. Use dynamo to vary the properties of model elements by using the slider or code block

Aim: To create an array of model elements in Revit

Introduction:

The Array tool creates a linear or radial array of selected elements. Use the Array tool to create several instances of one or more elements and manipulate them simultaneously. Array members can belong to a group; therefore, you can add or remove items from the group.

Procedure:

Step 1: Creating Elements in Revit

Open New Revit Architectural project

Create four columns in plan view

Step 2: Open Dynamo

Go to the Manage tab and open Dynamo
Open new workspace
Search Select Model ELements and

Select all the columns created in Plan view of Revit

Step 3: Adding Rotation

Search Set Rotation

Click to add to the workspace
Add a number slider for degree
Connect those as follows

Result:

The result of the above is as follows

4) Create a conceptual mass in Revit and develop a parametric column by dividing the surfaces and applying the concepts similar to used in parametric walkway modelling. Use triangular bent or square-shaped panels to add a finish to the parametric column

Aim: To create a conceptual mass in Revit and develop a parametric column

Introduction:

Creating conceptual mass families means that the mass is external to the project. It uses the same tools to create the mass family, which is then saved and loaded into the project.

Procedure:

Step 1: Open Conceptual Mass

Open New Revit Family
Go to FAMILIES and Conceptual mass

Clcik on metric mass to open Conceptual Mass

Step 2: Drawing Shape

Go to Level 1 Plan View
Draw Points at different elevations by changing offset distance

Connect them as the following using spline curve

Step 3: Setting Plane and Shape

Go to 3D view
Click on Set Plane and show the plane
Click on the point created and set the plane

Draw an ellipse as shown in figure

Similarly, create at all the points

Select all the ellipses created and click on "Create Form"

Result:

The result after creating the form is as follows

Click on Load into the project

5) Use Dynamo to work on developing a Parametric Stadium. List your parameters and use the visual programming approach to complete the modeling, You can use the concepts discussed in parametric high rise tower in class for reference.

Aim: To Use Dynamo to work on developing a Parametric Stadium

Introduction:

Creating conceptual mass families means that the mass is external to the project. It uses the same tools to create the mass family, which is then saved and loaded into the project.

Procedure:

Step 1: Opening New Project

Open New Revit Architectural Template and save as Project 3

Go to Manage Tab and click on Dynamo

Open new Dynamo workspace
