• Similarly select the type of floor in the floor type node and connect it to floor type in the floor outline node as shown below.

Result

Therefore, conceptual layout of floor plan using the tools available in dynamo is created in Revitas 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 : To create an array of model elements in Revit and vary the properties of the model elements using dynamo.

Introduction :

• Dynamo is the visual programming tool which is used to create the geometries by inserting the nodes and wiring them into proper sequence.
• By creating the model elements in the Revit followed by linking the elements in the dynamo we can change the shape or properties of element in Revit by operating on sliders of dynamo.

Procedure :

Step 1

• Open the Revit software and select architectural template.

Step 2

• Select the column architectural from architectural tab and insert the columns at the appropriate position as shown below.

Step 3

• Go to manage tab and select dynamo from visual programming panel and open the new file in the dynamo.

Step 4

• Type select model element in the library browser

Step 5

• Type integer slider in library browser and connect it to the rotation node by setting appropriate rotation angle as shown below.
• Select the select option from select model element node and select the columns from Revit software by dragging using the mouse.

Step 6

• Change the rotation degree using the slider as per requirement in the dynamo which is automatically reflected in the Revit screen as shown below.

Result :

Therefore, array of the model element such as column is created in Revit and model element is rotated by using integer slider in the dynamo as shown below.

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 surface using triangular bent pattern.

Introduction :

• Conceptual mass in Revit is 3D mass modelling.
• One of the purpose of mass modelling is to create 3D models of the odd shape building.
• By using this 3D modelling process we can create base of any odd shaped building.
