Revit railing enhancements with Dynamo

Lately I’ve been working on some Revit railing enhancements. This is still work in progress, but some of the Dynamo nodes are already available online in my updated Zhukoven.com (rev.2017.8.17) package. Below you can see available railing Dynamo nodes (please note that currently all of these nodes support only one railing instance at a time):

Railing.CalculateBalusterProfile

RailingBalusterProfile

Currently there’s no direct link between the railing element and its hosted balusters through the Revit API. So in order to get the baluster profile data, we have to explode railing geometry and extract surfaces. Output values are diameters / widths of baluster elements.

Railing.CountBalusters

RailingCountBalusters

This node calculates the number of railing balusters. See this post that explains the logic: Count railing balusters in Revit with Dynamo

Railing.GetHost

RailingGetHost

Check if the railing element is hosted, and get this host element as an output (if applicable).

Railing.GetPath

RailingGetPath

Get the list of lines that form the railing path.

Railing.GetTopRail

RailingGetTopRail

Get top rail element (instance) from the input railing instance.

Railing.TypeInfo

RailingTypeInfo

Input railing instance to get its type, primary handrail type, secondary handrail type, and top rail type. The node returns null values if selected railing type doesn’t contain handrails.

Dynamo deletes previously placed elements after each run – workaround

If you need to iteratively place multiple Revit elements with Dynamo, like these stadium chairs, then you are in trouble. The problem comes from element binding – a Dynamo feature which preserves the link between DesignScript and Revit elements during the current Dynamo session. This is how Dynamo works by design, preventing your model from an avalanche of element duplicates, created in ‘Auto’ mode:

DynamoBindingOn

Either you run the graph in ‘Auto’ mode (like in the figure above), or re-run the graph manually, Dynamo places new elements while removing previously created ones. This kind of behaviour sounds pretty logical and straightforward – look what you’ll get if there’s no element binding at all (using one of the workarounds):   Continue reading “Dynamo deletes previously placed elements after each run – workaround”

WhatsApp Dynamo package is now available for download

Today I released my tiny WhatsApp Dynamo package, and it’s now available for download and testing @ dynamopackages.com. WhatsAppDynamo provides integration with WhatsApp Web platform, allowing you to send text data (like URLs, file paths, parameter names, etc.) using Dynamo. Note that due to the platform limitations, images and files are not currently supported – they could be sent only as a hyperlink.

Currently WhatsAppDynamo package consists of a single custom node called “WhatsApp.SendMessage”. This node creates a WhatsApp message (string) in appropriate format to be used in WhatsApp Web platform. As I’ve already said, images and files are not supported due to WhatsApp limitations. Input desired phone number or leave this field blank (“UsePhoneNumber” switch is set to ‘False’ by default) to choose your contact later in browser.

Omit any zeroes, brackets or dashes when adding the phone number in international format: ‘+001-(555)1234567‘ must be converted to ‘15551234567‘ . Also please keep in mind that this phone number must have an active account on WhatsApp, otherwise you won’t be able to send your message.

Please feel free to test the package, and report issues & bugs here: Dynamo packages. It supports Dynamo 1.3.0+ & Revit 2016+

Count railing balusters in Revit with Dynamo

Counting something in Revit seems pretty easy, right? You’re able to extract lots of parameters from different element categories out of the box, and use them to create schedules or count quantities. This concept works great until you get to the system families. They usually make you scratch your head and turn your eyes towards Dynamo to get things done…

Say, we want to schedule the number of balusters by railing types. How are we supposed to count things like this?

Railings

The first thing that comes in mind – is to create a Railing schedule and check out available fields. And that’s when the first obstacle comes in your way: there’s no such thing as “Baluster” in the railing schedule:

The next step is to check railing instance or type parameters. Still, nothing useful here but baluster placement, that obviously can’t help us count the number of elements. Well, what if we check out available parameters in Dynamo?

Zhukoven.com dynamo package update brings Navisworks SearchSet XML creator

An updated version of my Dynamo nodes package (rev.2017.6.2) is now live at Dynamopackages.com. This version contains the Dynamo node that builds a Navisworks search set XML from the input data:

Navisworks.CreateSearchSet

Based on the original code by Luke Johnson from What Revit Wants (Bakery package), this node gives you the freedom in Navisworks XML file creation. You’re able to specify the Navisworks Search Set name & group, and choose which Navisworks parameter you’re going to use. This XML file stores data in the structured way that could be easily read by Navisworks. This means that you can use the power of Dynamo to automate your Navis searches, and even set the rules that couldn’t be otherwise done without workarounds.
