Answer :-

AIM :-

• To create a set of sinusoidal points and create a curve and create a surface out of the curve using Dynamo.

Introduction to DYNAMO :-

• 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.
• Using Dynamo, one can work with enhanced BIM capabilities in Revit.
• Dynamo and Revit together can be utilized to model and analyze complex geometries, automate repetitive processes, minimize human error and export data to Excel files and other file-types not typically supported by Revit.
• Dynamo can make the design process more efficient, with an intuitive interface and many pre-made scripting libraries available as well.
• User can connect different elements to define the custom algorithms that consist of relationships and sequences.
• These algorithms can be used on many applications, from data processing to geometry generation, with minimal programming code.
• Dynamo is considered a specific Visual Programming tool for designers, as well as a software that can create tools. These tools can use external libraries or any Autodesk product that has an API.
• Dynamo provides the framework as a Revit Internal Generative Design Tool. An understanding of how to work with a Dynamo Script created for Generative Design will help improve knowledge of Generative Design.
• User can be able to manipulate the Revit tool and the way it acts in the process. By adjusting the nodes and values ​​in Dynamo that are linked to Generative Design parameters, one can change the options once the Generative Design tool has been run in Revit.

Procedure :-

Step 1 :-

• Double click on the Revit application icon and opens the app.
• Open a new Architectural Template Project File.

Step 2 :-

• Go to "Manage" Tab and Click on "Dynamo" from "Visual Programming" Panel.
• Dynamo window will Open.

• Click "New" to open dynamo user interface.

Step 3 :- Creating Sinusoidal Points

• Go to Search bar and type "Code Block".
• Take three number of code blocks.
• Name them as "Start", "End" and "Step".
• Give values to Start, End and Step block as per choice.
• In this case Values are "Start = 10", "End = 300" and "Step = 1".
• Now Search "Range" and place it in proper position.
• Connect all above created blocks to the Range block.
• Now Search "Point by coordinates" and place the blocks in proper position.
• Connect the Range block to X-coordinate of coordinate block.

• For sin wave, go to library and Search "Math.sin".
• Connect range block to it.
• Insert an "Integer Slider" and Rename it as "Amplifier".
• Set the range as "Min = 50", "Max = 100" and "Step = 1".
• Insert "Product" operator from library and connect "Math.Sin" and "Amplifier" with that.
• Now insert an "Integer Slider" and Rename it as "Phase".
• Set the range as "Min = 20", "Max = 100" and "Step = 1".
• Insert "Add" operator from library and connect "Product" operator and "Phase" with it.
• Finally, connect the "Add" operator to Y-coordinate of coordinate block created earlier.
• Place all the functions boxes in a proper position.

Step 4 :- Creating Sinusoidal curve from Sinusoidal Points

• After creating sinusoidal points, we have to convert them to a curve.
• Now search "Nurbscurve" in library and choose nurbs cuvrve by control points.
• Connect the Points by coordinate block as input for the nurbs curve.
• A line is developed connecting the sinusoidal points.
• Place all the functions boxes in a proper position.

Step 5 :- Creating Surface from Sinusoidal Points

• The next step is to develop surface.
• First create node from selection.
• Select all the boxes and then go to "Edit" and click "Custom Node".
• Add Name, Discription and Category to the Node.

• Now copy this entire block two times to create the surface.
• Adjust phase range to view the two curves that is copied.

• Now create a list by searching list.create in the search panel of library.
• Add "Items" in the list block.
• Connect all the output of the sine curves as input for the list.
• This will serve as the input for surface by loft block.

• Now search "Surface by loft" in the search box and connect list output to that box.

• Sinusoidal Surface has been created.
