PParthiban Mani18 Aug 2023

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

Aim: -

Create a set of sinusoidal points using Dynamo

Create a curve

Create a surface out of the curve.

Procedure: -

Open Architectural Template in Revit software

Select manage tab

Go to visual programming panel

Click Dynamo It appear in new screen

In the home option click New

Go to library tab

Type Integer slider

Copy the Sliders and make it as 3 model spacing for sinusoidal points.

Double Click in the Integer Slider tab

Now, edit as the name Start, End, Step

Then change the values for minimum and maximum steps if required.

Now type Range in the library tab

Place the Range block in the model space.

Connect the 3 integer sliders to Range.

Now type point. by coordinate in the search tab.

We need two coordinate tabs in the model space.

Place them as two blocks.

Type Math. Sin in the library

Place Math. Sin block in the screen

Type code Block in the library

Place the Code block in the model space.

Type 50; value in the code block

Connect list seq in range block to 'X' in Point. by coordinate 1 block

Connect seq in Range block to 'X' in point.by coordinate 2 blocks

Connect Seq in Range block to "Angle" in Math. sin block

Type Product in the Library

Place them in a model space.

Connect code block to Point. by coordinate 1 block to 'Z' to 'y' value.

Connect sin in Math. sin block to point. by coordinate 2 blocks to 'X' value

Connect sin in Math. sin block to product operator block to 'Y' value.

Points are shown below into the figure;

Type NURBS in library.

Place by 2 control points as shown

Connect points by block 1 coordinate to NURBS curve 1 block

Connect points by block 2 coordinate to NURBS curve 2 blocks

Then type List create in the library

Create item 1 in the list block by clicking on + symbol

Connect NURBS curve 1 block to Item 0 in list create block

Connect NURBS curve 2 blocks to item 1 in list create block

Curve is created.

Type Surface

Select the By Loft Cross section option from the list.

Place it in the space

Connect list in the surface block

Surface is created as shown in figure.

Result:

Using points in Dynamo Sinusoidal points created.

Created a curve

Created a surface out of the curve.

Cross checked in Revit as shown below.

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:

To Create a conceptual layout of a floor plan in dynamo.

Procedure:

Open a New Architectural template

Go to manage tab and open the dynamo

Click new.

In order to create the wall, first we have to create two integers' sliders.

And four control points, For this search point by coordinates in the library.

Then give the values for sliders.

Now, we have to connect these points by a line.

Search by start and end point copy paste as 4 blocks.

The input for these blocks is the points created previously

Hence the layout of the floor plan obtained.

Now, Search wall in the panel and choose wall by curve and height.

For this input required curve height and level wall type.

For curve, combine all the four lines in a list by choosing list create.

For height, add slider and name it as height.

For level, search in library. place it

For wall type, search wall type panel and it will display the wall type.

The height of the wall can be adjusted using the slider.

Now we have to place the floor.

For this type floor in the library and select floor by outline curve, floor type and level.

Result:

Hence the conceptual floor plan layout has been developed and shown below:

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:

Create an array of model elements in Revit.

Procedure:

Open a new Architectural template in Revit software.

Go to Load family, select any elements as our wish.

Now, similarly Place it as 9 Array.

Now open Dynamo.

Go to search panel type select model elements, integer slider and set rotation.

The integer slider renames as degree

Then, select model element block will be input for family instance and integer slider to degree.

The rotation angle can be varied to desired value.

Result:

The model of element has been created and their properties are being varied through the block created in Dynamo.

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

Aim:

To create a conceptual mass in Revit and develop a parametric column by dividing the surfaces.

Procedure:

Open Revit software and under the families open as New

Select conceptual mass. open the metric mass file

Now, go to elevation view and create a level at 12' and name it as height of roof.

Now I am using spline tool to draw the desired outline for the walkway.

Then, we have to create a profile to sweep through the curve.

For this we have to set the work plane at the point and develop a polygon at the work plane keeping the point as center.

Now a polygon is developed as center.

Now we have to create the surface which is done through sweep.

For this select all the polygons and the curve line and choose create form option.

Now, select the entire form and then filter and retain only the form.

Now load this into the project.

Then select the entire form of the walkway and filter it to retain only divided surface.

Then in the pattern select the family that we have created.

Result:

The conceptual mass has been created in Revit and given as follows;

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