REVIT

Q.NO.1) Using Dynamo create a set of sinusoidal points and create a curve and create a surface out of the curve.

AIM:

Need to create sinusoidal point then curve from the point and then create surface

INTRODUCTION:

By using dynamo created a sinusoidal point then created a curve from the point and converted into the surface

PROCEDURE:

STEP 1) OPEN DYNAMO

Open Revit software
In new architectural template
Go to manage tab, click on dynamo under visual programming

STEP 2) CREATE NEW FILE IN DYNAMO

Click on new in dynamo window

STEP 3) CREATE SINUSOIDAL POINT

Insert 3 Integer Slider from Library and rename accordingly for Start, End and Step
Insert Range and connected all inputs from Sliders
Insert Point.ByCoordinate and connect “X” with seq (output of Range)
Insert Math.sin and provided input from seq (output of Range)
Insert Multiplication and CodeBlock (renamed with Curve)
Provided inputs for multiplication from Math.sin and Curve
Insert one more Integer Slider (renamed with Y-Point) and one Addition
Provided inputs for addition from Y-Point and Multiplication
Given output of addition to “z” point of Point.ByCoordinate

STEP 4) CREATE CURVE

Insert NurbsCurve.ByControlPoints
Provided input to NurbsCurve.ByControlPoints from output of Point.ByCoordinate
This will create Curve on the Sinusoidal points

STEP 5) CREATE CUSTOM NODE

Select all Output Nodes
Go to Edit > Create Custom Node
Provided Name of node as SinWave
Provided Description as Sine Wave Curve and Category as Revit
Click on OK

STEP 6) CREATE SURFACE

Copy all the input nodes and output nodes and past it 2 times
Change the value of Y-Points
Insert one List and provide the output of SinWave as an input to List
Insert one Surface.ByLoft and provide the output of List as Input of Surface.ByLoft

RESULT: After following above steps, we get the result of sinusoidal surface in Revit as shown below

Q.NO.2) Create a conceptual layout of 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 length of the wall.

AIM:

By using dynamo created conceptual wall layout of floor plan

INTRODUCTION:

To create the conceptual layout of a floor plan in dynamo, used available tool for joining the line, wall type and floor type and used sliders for height and length of wall

PROCEDURE:

STEP 1) OPEN DYNAMO

Open Revit software
In new architectural template
Go to manage tab, click on dynamo under visual programming
Dynamo window will open
Create a new dynamo model

STEP 2) CREATE POINT

Insert 2 integer sliders and rename with x and y
Insert 4 Point.ByCoordinates and rename them accordingly i.e. (0, 0, 0), (0, y, 0), (x, y, 0), (x, 0, 0)
Connect the output of integer sliders as an input of Point.ByCoordinates accordingly
4 points created, based on the length and width

STEP 3) CREATE LINE

Insert 4 Line.ByStartPointEndPoint
Provide output Point.ByCoordinates as an input of Line.ByStartPointEndPoint to connect the line between point accordingly

STEP 4) PROVIDE LEVEL, WALL TYPE AND HIGHT OF THE WALL

Insert a List Create and add the 4 items in list
Connect the outputs of each Line.ByStartPointEndPoint to one-by-one list items
Insert Levels and select the level1
Insert the Wall Type and choose the wall type as Generic 6” Masonry
Insert Integer slider and rename as Hight and change the Hight as required
Insert Wall.ByCurveAndHight and provide the inputs from List, Level, Wall Type and Hight

STEP 5) PROVIDE FLOOR TYPE

Insert Floor Type and select Wood Joist 10” – Ceramic Tile
Insert Floor.ByOutlineTypeAndLevel
Provide the input for Floor.ByOutlineTypeAndLevel from List, Floor Type and Level

RESULT:

After following above steps, obtain the result in Revit as shown below with appropriate wall length, width, height and materials

Q.NO.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

Answer3

AIM:

Need to create an array of elements in Revit and vary the properties by using slider or code block in dynamo

INTRODUCTION:

Created the array of columns in Revit and by using the integer slider from dynamo, rotate the column in Revit

PROCEDURE:

STEP 1) OPEN REVIT AND CREATE ARRAY OF COLUMN

Open Revit software
In new architectural template
Go to architecture and select architectural column
Insert 4 columns as shown

STEP 2) OPEN DYNAMO

Go to manage tab, click on dynamo under visual programming
Dynamo window will open
Create a new dynamo model

STEP 3) CREATE ROTATION IN DYNAMO

Insert Select Model Elements
Click on Select and select the all the column from Revit
Insert Integer Slider and provide the angle to the slider
Insert FamilyInstance.SetRotation and provide inputs from Select Model Element and Integer Slider

Result:

After following above steps, obtain the result as shown below, column as been rotated by 45 degree

Q.NO.4) Create a conceptual mass in Revit and develop a parametric column by dividing the surfaces and apply the concepts similar to use in parametric walkway modelling. Use triangular bent or square shaped panels to add finish to the parametric column

Answer4

AIM:

Create the Conceptual Mass in Revit, create a form and use property of triangular bent icon in the parametric column

INTRODUCTION:

Created a Conceptual Mass and developed a parametric column by dividing the surface and finish the model by using triangular bent shape

PROCEDURE:

STEP 1) OPEN CONCEPTUAL MASS

Open Revit software
Go to File tab > from new select Conceptual Mass
Select Metric Mass from Conceptual Mass folder > click Open

STEP 2) CREATE SPLINE COLUMN LINE

Go to east elevation
Click on model from modify tab then select pick line from draw tool
Provide offset of 12’ from Level 1
Go to level 1 floor plan
In create tab select spline from draw tool and create 4 points

STEP 3) CONVERT INTO PARAMETRIC SOLID FORM

In 3D view, select created column line
Set plane at each created point
Select polygon and create at all point with mass of 12’
Again, select created column line and first polygon
In modify tab, dropdown create form and select solid form

STEP 4) CONVERT SOLID FORM TO TRIANGULAR BENT

Select only form with the help of filter

Click on divide surface

After selecting the form change the property of pattern and number of U & V grid
Select the pattern Triangle bent

RESULT:

After following above steps, got the below shown result Conceptual Mass of parametric column and finished the model by using triangular bent shape

Aim:

To develop a Parametric Stadium using dynamo in Revit.

Procedure:

Initially open a new architectural template in Revit and then open dynamo.
Basic parameters to design a high rise structure is created as input in dynamo.
Four integer sliders is taken from the library for the following:
- Number of levels
- Floor to floor height
- Bottom floor rotation
- Top floor rotation

Now, insert a code block from the library to combine level and floor to floor height and type 0..#levels..Floorheight.
Now, connect the integer sliders named as levels and floor to floor hegiht as input to the code block.
Now, search coordinates by origin in the library and insert it.
Then connect the code block as input for z coordinate in the coordinate by origin block.
Five points are generated corresponding to 5 levels.
Now, insert rectangle by width and length from the library.
For this, inputs requied are coordinate system, length and width.
So insert integer slider for length and width.
Then connect the inputs for the rectangle block.
Now we have to rotate the geometry.
So, for this insert the rotate block from the library. The inputs required are:
- Geometry : Rectangle block
- Origin: insert an origin block from the library.
- Axis: insert vector Z axis from the library.
- Degrees: For this insert a code block and type Bottom..Top..#level. The inputs for this code block is already available i.e, Bottom floor rotation, top floor rotation and levels.
Now, we have to create surface, for this type surface by loft in library.
Then connect Geometry.rotate block as input for Surface by loft.
Hence, the parametric stadium have been created.
The number of levels and width and length of the rectangle can varied accordingly.
In revit structure is visible as follows:
