One of the most important issues during the daily work with Autodesk Revit is the need to Copy (Array) any architecture element along a pre-defined path, usually a curved one. Experimenting with the Array command in Revit, you will notice the provision of only two methods, Linear and Radial (or Polar), and that neither will help you to accomplish the required task. 

The best and the easiest method to solve this issue is to use Autodesk Dynamo. The package I designed here for you can help you to perform an array of any object along any type of paths. The concept behind the process in this package is to divide the path equally and place a copy of the required architectural element on the resulting divisions.

The following nodes are required:

Select Model Element: Select a model element from the document and it brings a copy of the Revit object into Dynamo.

CurveElement.Curve: Obtain the Geometry Curve for this geometry selection.

Curve.PointAtEqualSegemntLength: Return points spaced equally along the path length based on the input number of divisions.

Integer Slider: a slider that produces integer values, and in the context of this package it will provide the number of segments.

Family Types: All available family types in the document, and in the context of this package it will allow you to select the architectural element to make an array of it.

FamilyInstance.ByPoints: Place a Revit Family Instance given the family type (also known as the Family Symbol in the Revit API) and its coordinates in world space.

The result of this package allows you to array the required object along the required path. For example, you can use this method to distribute a lighting post along with curved curb, or make an array of columns along the perimeter of a free-shape Atrium.

The video included in this article will show you the required steps to achieve this package simply and easily.

The Array tool creates a linear or radial array of selected elements.

Use the Array tool to create several instances of one or more elements and manipulate them simultaneously.

Array members can belong to a group; therefore, you can add or remove items from the group. For more information about grouping, 

We use the Array tool to repeat elements along a path in Revit projects. This uniform repetition can be along a straight line, a curve, or even a spline!

The following short exercise will help you understand the basics of the Array tool.

Let’s start by adding a straight line and a curve to our active view.

1. Open floor plan: Level 1.
2. Go to the Annotate tab > Detail panel > Click Detail Line.
3. Draw panel > Line > Sketch a straight line.
4. Draw panel > Start-End-Radius Arc > Sketch a curve.
5. Select both lines.
6. Go to the Modify | Lines tab > Edit panel > Convert Lines.
7. Go to the Architecture tab > drop-down Component menu.
8. Click Place a Component.
9. Insert the element (Component) on the model line.

It’s now time to use the Array tool.

Linear Array

Repeat an element along a horizontal or vertical line.

Steps

1. Click on the element.
2. Go to the Modify | Element tab > Modify panel.
3. Click on Array (Shortcut: AR).
4. Options bar > Linear.
5. Options bar > Number > Assign an amount of elements.
6. Options bar > Move to > 2nd.
7. Click on the point where the Array starts from.
8. Move the mouse cursor over it and click once to set the distance between the elements (over the blue dashed box).
9. Enter the number of elements to be inserted after > press Enter.

AIM :

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

 

PROCEDURE:

open revit ,go to manage tab and select dynamo,

we get an interface as shown below.

Creating conceptual mass families means that the mass is external to the project. It uses the same tools to create the mass family, which is then saved and loaded into the project.

In-Place Massing (in project) Massing & Site > In-Place Mass

Conceptual Massing Environment (outside project) Revit > File > New > Conceptual Mass

 

Creating a Conceptual Mass Family

 

 

• Revit > File > New > Conceptual Mass

  

• Select a conceptual mass family template
• Click ‘Open’ (This opens the conceptual mass environment.)

  

 

 

* You can use massing templates that are set in line with company standards or create a template unique to the project.

The modeling tools are identical to those found within the project environment. The conceptual mass allows you a bit more control with the added advantage that levels are visible in 3D. Here’s what to do after opening the family:

 

 

• Select
  draw tool (see in toolbar above) and draw on a work plane in plan view or elevation/3D view.

   

  

• The
  shape you draw can be edited at any time using the ‘Edit Profile’ function.

   

  

• Create
  geometry from shape and manipulate the mass as needed using the ‘Create Form’
  command.

   

  

• Join two or more masses, add voids, etc.

 

 

Note: Generic Mass Family has one level at ground 00 and two perpendicular work planes:

 

You can control whether a view displays masses via either using view settings or settings in the Visibility/Graphics dialog. Same for controlling whether the view shows mass floors, surfaces, and zones.

---

Loading into the Project

 

 

• Open your Revit project.
• If using worksets, activate a workset in which the mass is going to be modeled.
  
• Ctrl tab back to conceptual mass family.
  
• Click ‘Load into project and Close’. If you currently have more than one project or family open, you will be prompted to select the Revit project name.
  

 

 

*Family parameters can be used as per standard family creation.

 

Revit model space lets you work simultaneously with in-place masses (system families) and mass families (conceptual mass families). Family parameters and materials can be applied to mass families, and elements like roofs, floors, etc. can be generated.

In Part III of Revit Massing we will look at how to apply geometry to masses, i.e. create building elements for project masses. Stay tuned!

5)

We will start form constructing elevation. In a first step we will define basic shape of a stadium and create list of knot points which we will use to create structure.

 

The shape of Volgograd Arena is defined by to circles. The one on top has a bigger radius than this of a base. Basing on information found online we made the height of the elevation is 40 meters, diameter of upper circle 151.5 meters, base circle is smaller by ¼ of height.

 

 

There are 44 columns around the stadium so we have to divide both circles into 44 equal segments. We used Curve.PointsAtEqualChirdLength component for this. It outputs all points which are results of division so we have to add end points to the list. At the end we have to marge two lists with List.Join.

 

 

To create diagonal patter of facade for have to shift list of points by to steps to the right and then to the left. Now we can connect points from the base and to shifted stet of points to create lines of this pattern...

 

 

The last step is to find intersection of this lines and sort list of this points by levels. For finding intersections we used Geometry.Intersect component.

 

 

Sorting list of points required a little bit of scripting. List of points was sorted by Z parameter of points, numbers were rounded to avoid errors.

 

import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
#The inputs to this node will be stored as a list in the IN variables.
messyListOfKnots = IN [0]

list_of_knots = []
for i in range(0,5):
list_of_knots.append([])

for i in range(0, len(messyListOfKnots)):
  if round(messyListOfKnots[0].Z)== round(messyListOfKnots[i].Z):
   list_of_knots[0].append(messyListOfKnots[i])
  if round(messyListOfKnots[1].Z) == round(messyListOfKnots[i].Z):
   list_of_knots[1].append(messyListOfKnots[i])
  if round(messyListOfKnots[2].Z) == round(messyListOfKnots[i].Z):
   list_of_knots[2].append(messyListOfKnots[i])
  if round(messyListOfKnots[3].Z) == round(messyListOfKnots[i].Z):
   list_of_knots[3].append(messyListOfKnots[i])
  if round(messyListOfKnots[4].Z) == round(messyListOfKnots[i].Z):
   list_of_knots[4].append(messyListOfKnots[i])

#Assign your output to the OUT variable.
OUT = list_of_knots
