Creating Conceptual mass in REVIT and Creation of Sinusoidal curve and a Parametric stadium using Dynamo

1) Using Dynamo create 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 a open source visual programming language for revit. This allows to type lines of code and also creating an algorithm that consists of nodes. Each node perform a specific task and each node consists of input and output. The output from one node is connected to the other node in from of wires. The program flows from one node to other node through the wire networks and the final output is the graphical representation of a model.

In this project, I create a set of poins in the x-axis by using nodes and connect to the other nodes to form a sinusoidal curve and make simalar curves by grouping the nodes and change some parameters. Finally make a surface through the sinusoidal curve.

Procedure:

• Open a new project with architectural template.
• Select 'Dynamo' under manage tab.
• Once the dynamo window opens, Select new.
• First Create a set a points in the X-axis.
• For that, Introduce three integer sliders and rename it as start, end and step.
• Introduce one range node and Points by coordinates node.
• Connect the wires from sliders output to range input and range output to points by coordinates input in the X Coordinate.

• Now create a sinusoidal pattern from the points created.
• Introduce math.sin, Integer slider, Code block, product and addition nodes.
• Rename the code block as amplifier and set the value as 10.
• Connect the range output to the math.sin input.
• Connect wire from math.sin output to Product node input X and amplifier ouput to product input Y.
• Connect Wire from product output to Addition input X and Integer slider to addition node Y.
• Finally connect the wires from product output to the points by coordinates input in the z-axis.

• Create a Line that connects the sinusoidal points.
• Create a nurbscurve by coordinates node.
• Connect the wire from proints by coordinates to nurbscurve by coordinates.

• Create a similar sinusoidal curves.
• For that create Custom node from all the outputs.
• Select all the output node and select create custom node in the edit tab.
• Then name it as Sin curve, Write the discription and select the categories as revit.
• Once the group is Created.
• Select all the nodes and make two more copies.
• increase the phase values as 22 and 50 for the another two copies.

• Now create a surface through the sinusoidal points.
• Introduce list and Surface by loft nodes.
• Connect the wires from All the nurbs cure to the list.
• Finally connect the wire from list output to nurbs curve by loft input.

Result:

A set of sinusoidal points and curve is created and surface is created out of the curve.

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 floor plan in dynamo.

Introduction:

In dynamo nodes are objects these connect to form a visual program. Each node performs an operation, sometimes as simple as storing a number or it may be a complex action such as creating geometry. The geometry created by using nodes is replicated in the revit.

In this project, I create a nodes that perfoms an operation like inserting points, Creating walls and floors by connecting the nodes by using wires.

Procedure:

• Open a new project with architectural template.

• For that introduce two integer sliders and four points by coordinates nodes.
• Set the value as 100 in integer sliders.
• Connect the wires from the integer sliders to points by coordinates inputs.
• Connect the wires as shown in the figure below.
• That creates the points at the orgin, 0,100 , 100,100 and 100,0

• Now to create a points for the internal walls.
• Again introduce three integer sliders and four points by coordinates nodes.
• Set the values as 50 and 100 in the integer sliders.
• Connect the wires from the output of integer sliders to input of points by coordinates node as shown in the below figure.
• This create a points 0,50 , 50,50 and 50,100

• Create a line through the points to make a conceptual layout.
• For that introduce four line by start and end point nodes.
• Connect the wires from the points by coordinates to line by start and end point nodes.
• Connect the wires like the below figure.
• This create a out line of the conceptual floor plan.

• Create internal wall lines.
• For that again introduce three line by start and end points node.
• Connect the wires from the points by coordinates to line by start point and end point nodes.
• Connect the wires like the below image.
• This create the lines in the internal points.

• The conceptual line layout is created.
• Now create a Wall.
• For that introduce list node.
• Connect the wires from the points by start and end point output to the list node inputs.
• Introduce wall types node and select the wall type as 'exterior-Brick on Mtl. stud'
• Introduce levels node and set the level as 'level 1'

Array is the concept of creating copy of the element in a series manner. In this project, I create an array of a column in revit and changing the properties of the column by using familyinstance set rotate node in dynamo.

Procedure:

• Open revit software.
• Create new project by architectural template.
• Select architectural column under the arcitectural tab.
• Create one architectural column of size 24''X24''

4) Create a conceptual mass in Revit and develop a parametric column by dividing the surfaces and apply the concepts similar to 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 and use triangular bent to add finish to the parametric column.

Introduction:

Conceptual mass family means that the mass is external to the project. It uses the same tool to create a mass family, which is then saved and loded into the project.

In this project we create a conceptual mass of a column by using the spline curve then create a mass and add a triangular bent finish to the column.

Procedure:

• Open revit software.
• Select new families, select conceptual mass and select mertic mass.
• Create a mertic mass template.

• Go to east elevation.
• Select one level at a distance of 1000 units from the existing level.
• GO back to the plan view.
• Select spline option.
• Create one spline curve.

• Select set work plane option under the work plane panel.
• Set a work plane at the start point of the curve.

• Create inscribed polygan of 4 sides at a distance of 5000 units from the center.

• Similarly set the work plane to all the other points.
• Create a inscribed polygan to all the work plane.
• Now create a solid form to the curve.
• Select the curve and the inscribed polygan.
• Then select solid form option.

• The solid form of the curve is created.

• Add triangular bent to the solid form.
• For that select the solid form and click teh divide path option.
• Select the solid form and now select the divide surface option.
• Now the model is ready to add the triangular bend finish.
