Dynamo 1.3 Released!

Did you see the green cloud in Dynamo today? There’s a new release available.

Visit this page for the full report.

From the readme file:

New Functionality

– Geometry Working Range, a solution that adjusts numerical precision to accommodate these large numbers.
– Isolate Selected Geometry
– A direct link to the Dynamo Dictionary is added at the bottom of help menu popup window for each node. Definitions are currently available for the out-of-the-box core Dynamo nodes, and we are actively working on Revit nodes.
– Multi-output port re-connect feature using Shift+Left-Click
– Highlight geometry from selection in preview bubbles and watch nodes.
– DateTime.Format: (shout out to Radu Gidei!)

Dynamo Studio:
– Translate (CAD import) functionality now supports 3DM (Rhino) and SAT file formats, in addition to DWG and DXF. (Additionally, import of FBX, OBJ, STL, and SKP formats are supported, but there is currently limited downstream capabilities with these meshes.)

Dynamo for Revit:
– Revit allows for duplicate parameter names in a file, and Dynamo is now able to consistently pick between Named or Built-In parameters.
– Preview Bubbles enabled for Revit Selection nodes
– New Revit nodes: a number of Creation methods for System Families, added access to Global Parameters, and exposed file auditing tools with the Performance Advisor.

Bug Fixes
– Fixed line break issue in for group titles, increased group titles font size
– Convert between units now gives correct Hectares for Area conversion
– Fixed File Paths with spaces sometimes converting paths to escaped URI path
– Fixes to Arc.ByCenterPointRadiusAngle, Arc.StartAngle, and Arc.EndAngle




I’m bringing some more standards tools to you today. A quick copy and adjust of the original text tools graph resulted in three tools for dimension styles. The first allows the user to select a dimension type and then selects all elements in the current project that use that style. The elements are selected in Revit, so the user can use the type selector to change the type.

3 tools in One Graph

The second tool reports all dimension types and writes them to the chosen excel file in a worksheet named dimensions after the category chosen.

The third tool allows the user to choose a dimension type and change the elements selected by the “type” filter and change their family type to the desired type within Dynamo.

Here is a the complete screen capture of the 3 tool graph.

This workflow starts with the category and achieves the same result, in a lot fewer nodes.  Grab a copy here:


Dynamo Based Project Review

Dynamo Based Project Review

As I was updating existing templates and building some new ones, I wanted a better way to determine what fonts/text styles are in use and where they are being used.

Exploring some existing dynamo graphs and custom nodes, I put the following graph together.

capture info
Full Capture

This graph searches the current project, builds a list of graphic views (plan, section, elevation, drafting, legend, and callout) and then builds a list of elements in those views.

The data is then output to an excel file for review. Here is what the output looks like.  As you can see, the graph outputs the textnote style and the viewname the text element was found in.


Excel Image
Output from Graph


For those of you who want to do it yourself and understand how I reached the working version of the graph, follow along as I describe how I created the graph.

Input graph section
Input Path to excel, and boolean toggle


First Step – Insert the White_Dynamo_Graphic_Standard node, edit the custom node and copy all the precreated groups, pasting them into your new home workspace.  I edited the file notes contained inside this standard and saved it so I have a ready to use set of groups whenever I need them.

Since we are trying to determine where standard elements are being used in projects and templates, and I know I want to be able to reuse the data in excel, lets get started with the beginning and end in mind.  Type excel into the search tool in the Dynamo graph editor and add the Excel.WriteToFile node.  This node presents a number of connectors helping us to quickly add the necessary inputs by search.

Excel Write to File Node Image
Excel Write to File Node

Add a File Path node, a Categories node, and a Boolean node as we will be able to quickly connect these up as we begin to think through the logic of what the rest of the graph will require.   I prefer the the file path node to a string based input, because I can select an excel file by browsing to it.  The categories node allows us to select the category to be reviewed (Text Notes).   I will add a “String from Object” node and connect it to the Categories node, so I pass in the sheet name directly from my chosen category.  The boolean node lets us control whether the data is refreshed and whether the excel file is overwritten.  I know that I want to start filling the excel file from column A and Row 1, so I’ll add a code block by double clicking in the editor and preparing to pass out a value of zero.  I will connect up the nodes like this:

Begin with the End in Mind Image
Begin with the End in Mind

As you can see in the image above, I have already provided 5 out of the six input nodes required by the Excel.WriteToFile node.  So now we tackle the data input.  Since I want to figure out where all my text note styles are being used, so I can standardize the text note styles, I’ll next add the Document.Views node from the clockworks package to generate a list of all views contained in the current project.  Click on your Excel.WriteToFile node, right click your mouse and freeze this node til we have the data input prepared. Click run to see the output from the Document.Views node.

First Design collection
Graph Design Area 1

I added and connected the Lunchbox node: Remove Null Values to the output of the Document.Views node, because I saw some null output after running it the first time.  Looking at the list of views provided, I realized that there were many views that would not be of use to me in this process, so I searched for a node that could give me a way to filter out these nodes.  Having found no such node, I decided to modify the View.IsTemplateView node from Clockwork for my use.  The easiest way, I’ve found is to simply add this node to your graph, then select it and right click choosing to “Edit custom node”.  Once the node is open in the editor, copy all the internal nodes to the clipboard and then close the View.IsTemplateView node.  Remove it from your graph and click “File” new custom node.  When the editor opens, paste the contents of the clipboard to your new custom node.  It should look like the following image:

custom node content image
Custom Node Contents

I named my custom node: View.IsGraphicView and added it to the BesideTheCursor Package, I’ll publish it later tonight or tomorrow.  In the mean time, you can do what I did and modify the python script as shown in the image below.  I added some exclusions of view types to exclude.  This results in a view filter that effectively rips out the views that wouldn’t contain graphics.

Custom Python Code
Custom Python Code

I modified the original python code very slightly, see the difference view image below:

image 3
View Nodes Code Difference

I used a boolean if else line to accomplish what i needed as seen in the images above.  A quick run of the partially completed graphs shows that I am now effectively identifying the views that I do not wish to process.  I can use the true false output from my new custom node with the List.FilterByBoolMask to filter out the view types I no longer want to include.   I connect my node to the bool input and connect the cleaned output to the list input on the List.FilterByBoolMask node.

View.IsGraphicvView in action
Identifying True and False

I am now ready to pass my list of included views into the Springs.ElementsFromViews node, to begin building the list of elements found in every view. A quick run at this time reveals many thousands of elements.  Don’t get worried by the spinning blue wheel.  It will run to completion rather quickly.

count of elements in views
Element Count is High!

Now its time to filter for the type of element I’m looking for.  We can add a code block and type in the TypeName description for TextNotes.  You can see what is required from the Object.Type node.  We connect this into the String.Contains node to search our large element list and build a boolean list of true and false.  Connect these up to a List.FilterByBoolMask and then flatten the output will complete our data filtering down to just TextNotes as shown below.

Filtering Element Types

Lets add some more nodes.  Add Element.OwnerView, Element.Name (Universal), TextNote.Typename and we’ll connect them up and build a new list using List.Create with two input connectors as shown below:

ViewName Id
Getting View Names from Elements

Lets run this graph and take a look at the output from our list to this point.  As can be seen in the image below, we are getting two sublists; the first contains the viewnames and the second list contains the textnote typenames.  Having worked with the Excel.WriteToFile node in the past, I know from experience that the data input node prefers lists that contain rows and columnar data.  Lets add the List.Transpose node to convert our list to this format and connect it into the Excel.WriteToFile data input connector.  Now its time to run the graph, so unfreeze the final node and get ready to review your list of textnotes used by view.  You can grab a copy of the graph here:, but its always best to build it yourself to gain a better understanding of how Dynamo works.

During the process of writing this blog post, I realized that the path I took was longer than necessary and can actually be accomplished without the custom node created, but what fun would that be?  Check back later for an update and a simpler graph to complete the same workflow.

Macro: Create Isolated 3DView based on Workset

Macro: Create Isolated 3DView based on Workset

Finally got around to adding the code to modify a great routine published by Harry Mattison back in 2015.  I’ve been using the routine to generate the isolated 3D views, but from the first time I ran it, I wanted a way to do workset isolation rather than element level temporary isolation.  Using the Harry’s original code, I added a dictionary and the SetWorksetVisibility code segments.  The code published below will set the workset visiblity for the view in addition to the element.

Harry’s original post

My modified code shown below (Application Macro):

public void CreateIsolatedWorksetView()
Document doc = this.ActiveUIDocument.Document;
int max = 100;
if (!doc.IsWorkshared)

// get the 3d view type which is needed when creating 3d views
ViewFamilyType vft = new FilteredElementCollector(doc)
.FirstOrDefault(q => q.ViewFamily == ViewFamily.ThreeDimensional);

using (Transaction t = new Transaction(doc, “workset view isolation”))
// create a dictionary to hold the worksetid and workset name
Dictionary<string, Autodesk.Revit.DB.WorksetId> dict =
new Dictionary<string, Autodesk.Revit.DB.WorksetId>();
// loop through all worksets (but only User worksets)
foreach (Workset wset in new FilteredWorksetCollector(doc).WherePasses(new WorksetKindFilter(WorksetKind.UserWorkset)))
dict.Add(wset.Name, wset.Id);
foreach (Workset wset in new FilteredWorksetCollector(doc).WherePasses(new WorksetKindFilter(WorksetKind.UserWorkset)))
// create a 3d view
View3D view = View3D.CreateIsometric(doc, vft.Id);

// set the name of the view to match the name of the workset
view.Name = “WORKSET – ” + wset.Name;

// isolate elements in the view, using a filter to find elements only in this workset
view.IsolateElementsTemporary(new FilteredElementCollector(doc).WherePasses(new ElementWorksetFilter(wset.Id)).Select(q => q.Id).ToList());
view.SetWorksetVisibility(wset.Id, Autodesk.Revit.DB.WorksetVisibility.Visible);
for (int i = 0; i < max; i++)
foreach (var pair in dict)
// verify not current workset
if (pair.Key != wset.Name)
view.SetWorksetVisibility(pair.Value, Autodesk.Revit.DB.WorksetVisibility.Hidden);

Cumulative Area and AutoCAD Hatches

Cumulative Area and AutoCAD Hatches

I was asked this question recently:

I noticed the “cumulative area” when attempting to add up SF numbers from multiple polygons. Please see the two images below. Why can I select 4/5 polygons and have it add them in the cumulative area space (Shown in Image 1) but when I select the 5th area the cumulative area disappears (Shown in Image 2)? Do you know why this occurs?

Screen Capture 1
Image 1
Screen Capture
Screen Capture 2

I suspected that there was a boundary issue, that prevented the hatch from calculating the area.  This can occur when a polyline boundary overlaps itself before its closed.  Since a hatch can generate a new boundary, I felt that was the easiest way to resolve the problem.  Here is my response:

The problem exists with the last hatch area. If you select it by itself, it displays no Area. I suspect that the boundary is probably overlapping itself. It’s not related to the number of hatches chosen, it’s actually that hatch by itself. To fix it, I did this:

1.) Unfreeze the layer containing the hatch, and make it current.
2.) Isolate that layer so only the hatch objects are visible. You can use layiso to isolate the layer containing the hatch.

Screen Cap 3
Image 3

3.) Now that the hatch is visible and isolated, select the problem hatch, right click and choose generate boundary.

Screen Capture 4

4.) Once the new boundary is created, you can delete the original hatch.
5.) Use boundary hatch to place a new hatch into the generated boundary, to match existing hatches already created, you can use match properties.

Viola problem solved.

Revit Dynamo Parking Tools

Revit Dynamo Parking Tools

Working on some tools to assist the design teams in managing parking spaces.  The attached graph contains two tools.  The first tool renumbers parking spaces based on a model based spline drawn through the spaces.  Refer to the image below for more info.

Controls in Dynamo
Renumber Parking

The instructions to renumber the parking spaces are shown in the blue area in the image and listed below this paragraph.   Use the control toggle boolean node to run one graph at a time by setting its value to true and the other node to false.

To renumber existing parking tags based on spline

1.) Draw a model line using the spline tool. If your sketch contains multiple sharp curves, you may need to increase the “Integer Slider” amount to ensure the routine gets all the parking stalls. 400 is a good starting number.
2.) Start in lowest number parking spot, continue spline through parking spots in order ending the spline in the spot you wish to have the highest number.
3.) Use Select Spline (Model line) “Change” button to select the model spline in your project.
4.) Enter desired starting number for in Starting number node.
5.) Enter desired increment amount

Click Run when Ready

The second tool addresses parking spaces on ramps.  It requires a custom parameter named SCHEDULE LEVEL.  Use the second tool to write data to the parameter.  You can use this to filter your parking schedule.

The instructions to update the parameter are shown in the blue area in the image below and are listed below this paragraph.

Assign Parameter
Updating custom shared parameter using dynamo

To Assign Schedule Level

To differentiate between level based parking and ramp associated parking, perform the following steps:

1.) Click Select model elements and window the parking elements that are to be associated with the ramp.

2.) Click True to run this operation or False to run a different operation.

The image below shows the entire graph.

Dynamo Checkerboard Curtain Wall Panel Tutorial

Dynamo Checkerboard Curtain Wall Panel Tutorial


Rowlock Brick Checkerboard
Architect’s Sketch

This post will describe a fairly simple graph for offsetting alternating curtain panels in a curtain wall.  The idea was generated by a request for a checkerboard rowlock brick wall accent.  I’ll break down the dynamo graph for you in pieces.

Prior to getting started, make sure you have installed Dynamo Version 1.2.0 or higher.  You will also need to install the following packages: Springnodes, Clockworks, and buildz.  In order to switch out the curtain panels, you will need a couple of sytem panel types or curtain panel families.  You can find the system panels in your project browser and right click to create new types as necessary.

CW Panel Type Image
Create New Panel Type

Once you’ve created the new types, right click the type and set the appropriate properties to create the offset surfaces or alternating patterns to be used.

Duplicate, Duplicate, Duplicate
Right Click to Duplicate the panel type once created.

In this example, I’ve created two new system panel types: Brick_Flush, and Brick_Offset.  I also edited the type properties and added a brick rowlock material.  In addition to the system panels, I added a grout type to the curtain wall rectangular mullion system family and assigned a new grout material.

Resulting Checkerboard Offset Rowlock Brick wall

The above image is the result of the graph shown below which collected all the curtain panels from the user selected curtain wall.  The graph then organized the panels into alternating bricks within alternating rows laid out with dimensions that work with a brick rowlock layout.

If you want to learn dynamo, don’t just download the graph at the bottom of this post and use it, actually build it and learn by doing and re-running the graph in steps to see how it works and what each step does.  Ready to learn? Here we go.

Launch Revit and draw a curtain wall.  To replicate the brick rowlock checkerboard curtain wall, adjust the properties of the curtain wall to match these settings:

Element Properties of the Base Curtain Wall

The initial “Rowlock Brick Curtain Wall” shown above.

Note: I have already created the Rectangular Mullion Type to represent the 3/8” thick grout between the bricks.  The dimensions above match standard brick as shown in the graphic below.

Brick image
Standard Brick Rowlock with dimensions.

Launch Revit Dynamo from the Addins tab and using the node search function, add the following nodes and connect them together as shown in the image below: Select Model Elements, CurtainPanel.ByElement, and CurtainPanel.Sort.  Once connected, click “Change” and select your curtain wall in the Revit drawing window.

Revit Dynamo Curtain Panels
Collection of Curtain Panel elements in Revit Dynamo

Once you’ve connected the nodes together and selected a curtain wall, click Run, then hover over the lower right corner of the sort node to see if you’ve gotten any panels in the data list.  The CurtainPanel.Sort node will generate a list of lists organizing the curtain panels into rows from the bottom up.

To see the results of our work, lets add the “FirstItem” node and the “Element.Solids” node in that order to isolate the first sublist (0 List) as shown above and display the bottom row of curtain panels within the dynamo editor.  Click Run, your dynamo window should resemble the following image:

First Row of Curtain Panels
First row of curtain panels isolated by List.FirstItem

Using List.FirstItem and Element.Solids gives us visual feedback within the dynamo editor. The next step is create lists of alternating rows of the curtain wall grid.  Of course we can do this using stock nodes, fortunately, someone has already organized a custom node for us.  Add the Springs.List.GetEvenOdd and connect it to the CurtainPanel.Sort node.  Now click the Odd output connector and connect it to the “List.Firstitem” input connector.  Lets run the graph again and look at the results. Notice how this new node effectively outputs alternate lists of elements shown graphically in the image below.  Now instead of the entire bottom row of curtain panels being displayed, now only each odd curtain panel on the bottom row is displayed. Switch the output to even and re-run it to see the other panels.

Curtain Panels
Alternating Curtain Panels in bottom row (List 0)

If you bypass the “List.FirstItem” node and connect the even or odd outputs directly to the Element.Solids node, you’ll see exactly what the GetEvenOdd node is doing.  It is creating lists of the alternating columns. Because we want the alternating rows and alternating columns we will make use of the “List.Transpose” node along with two more …GetEvenOdd nodes.

Alt Curtain Panels rows and columns
Alternating Curtain Panels in rows and columns

In order to generate our checkerboard pattern, we are going to have to build lists of alternate rows as well as lists of alternating panels within each row. Let’s adjust our graph a little further. Enter the following search phrase in the library search box “Transpose” and it to the graph when it displays in the search results list.

List Transpose node
Use this node to swap rows for columns in your list collection

Select the List.Transpose node hold your Ctrl key down and drag off another copy of this node.

Now Click to select the “Springs.List.GetEvenOdd” node, hold the Ctrl key down as you drag off a copy of this node. (You can also use copy / paste within the dynamo editor). Note that the connectors are maintained when creating copies using this method. Click to unselect them.

Connect each transpose node to an output connector from the original …GetEvenOdd node, now connect the new …GetEvenOdd input connectors to the output connectors from the transpose nodes as shown in the image below

Organize Alternating data node
List.GetEvenOdd Node from Springworks

At this point, if you want to duplicate the solids node another 3 times you can connect them to the four even/odd output connectors to see what each output list contains individually (the download is organized this way for learning purposes).  Note, when you click on the Element.Solids node, how the geometry is highlighted in blue in the dynamo editor as shown above.

Since we are alternating only two types of panels in our curtain walls, we will use the List.Create node to recombine the output lists in an organized fashion.  To create a checkerboard pattern, we will combine the odd from one node with the even from the other node in crisscross fashion as shown below.

criss cross connectors
Collection across outputs is how we build the checkerboard pattern

Now that we’ve reorganized our curtain panel lists, its time to change the curtain panel type.  Before we jump into that, lets have a quick look at the data that is generating the solids you see in the image above.

Nested List of LIsts
Nested List of LIsts

As you can see in the image above, the result of our reorganizing has created some very deeply nested data.  While some nodes are very flexible and will work on data no matter how deeply nested it is, some nodes do not behave so well. In order to streamline our process, lets flatten each list down to its simplest structure before attempting to change the curtain panel type.  Add a “flatten node” for each output.  Use the Builtin version of the flatten node to reduce the 4 deep list of lists to a single list of panels as shown below:

flatten node at work
Flatten the lists of data for use downstream

Click in the Library search box and enter this keyword: “FamilyInstance”, choose the second one in the list displayed. “CurtainPanel.AsFamilyInstance”.  You’ll add two of these and connect them to each of the flatten outputs.  Enter “SetType” in the library search box and add two FamilyInstance.SetType nodes as shown in the image below:

Family Instance Set Type
Family Instance Node needs an element list and a type

Note that the FamilyInstance.SetType node also needs and input of the familyType to be set.  Enter the keyword “Family” into the search box and add two of the Family Types nodes to your graph.  Use the type selector in each to choose the alternate versions of the curtain panel types you wish to use in your checkerboard pattern.

Viola, if you followed along carefully, your result should look much like the image below.

Final result in Dynamo Graph
Swapped Types

I hope you were able to follow along and add this workflow to your Dynamo repertoire.
