Sneak peek into Dynamo 2.0

It’s been a while since the last “major” Dynamo update (Dynamo 1.0 was released way back in 2016). And if you are tired waiting for something new, you can download and install one of the latest Dynamo 2.0 daily builds from the Dynamo development builds webpage.

Starting from this year’s daily builds, Dynamo team has changed the way Dynamo installs, so that it doesn’t interfere with existing 1.x installs:

  • DynamoCore and DynamoRevit will be installed in the folder named using DynamoCore major version instead of major version point minor version;
  • Installing the new Dynamo 2.x build should not affect your existing Dynamo 1.x installed;
  • Installing a new Dynamo 2.x build with a larger minor version will overwrite the content in major version folder.

Considering that Dynamo 2.0 will save files to a format that is not compatible with earlier versions, it is highly important to backup your existing Dynamo content folders. Please read this safety note from Dynamo team before downloading and installing daily builds:

These are the early stage builds that are leading to the Dynamo 2.0 release. Please keep in mind that it is early days for these builds, there are still a number of large moving pieces and, as always, this area should be treated as an active construction site. If you do decide to participate, please wear your hardhat!

Dynamo 2.0 brings a plenty of changes, including:

  • New JSON file format instead of XML-based one;
  • Updated node library with different organization:  Dynamo2.0_Library
  • New OOTB (out of the box) dictionary nodes:Dynamo2.0_Dictionary nodes
  • Custom packages have been moved to the dedicated “Add-ons” submenu;
  • Usability fixes for those who work with Python (code execution button, custom templates, multiple editor windows, etc.).
  • And, of course, a lot of tweaks under the hood. You can view the full list of the future changes here.

Dynamo 2.0 can be installed side-by-side with existing 1.x versions, allowing you to experiment with the early pre-release tools without interfering with your existing workflows. You will be prompted to choose which version you wish to run when first launching Dynamo in Revit:

Dynamo2.0_Launch

This setting will be saved per-session of Revit. Restarting Revit will enable you to switch to a different version of Dynamo. Please don’t forget to back up your existing Dynamo workflows, packages and files. And do not use unstable software in the real project environment!

Autodesk Building Performance Analysis Certification Retirement

Today is the last day to finish your Autodesk Building Performance Analysis Course and earn the certificate before the entire course gets retired.

BPAC-Badge

If you are currently enrolled in the course, you’ll have time until December 15th, 2017 to finish it. Any non-completed courses will be de-activated together with the training portal after December 15th, 2017.

But don’t worry, all of the course content (excluding quizzes) is already available in Autodesk Sustainability Workshop: Building Performance Analysis Course page.

The course itself won’t disappear: the authors are currently working on bringing BPAC to Autodesk Design Academy portal in the next coming year.

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.

Revit 2018.1 update comes with enhanced Dynamo Player

Good news, everyone! Revit 2018.1 update is now available for download from the Autodesk Account portal. It comes with some cool new features (see this article at Autodesk blogs for the full info), including enhancements to Dynamo Player. Now it finally supports changing input values directly through the Player UI, which is super handy:

Dynamo_Player_update_2018.1

As you can see, there may be plenty of inputs that could be changed without even launching Dynamo. But note that there are still some limitations:

  • Code blocks as input strings are not  supported – if you prefer to write text inputs in code block, using quotes, you’ll need to rebuild these Dynamo graphs (swap Code Blocks with Strings) to use with Player;
  • Custom nodes as inputs are not supported – they are not shown in the Player UI;
  • Frozen nodes will be shown as changeable inputs, while they’re not used in the script logic.

Anyway, this is a cool update, and I’m sure that these subtle issues would be fixed in the near future. And by the way, here is the quote from Dynamo community addressing these issues:

We will look into the frozen node and address them in the future.
For the Code Blocks it’s a little more tricky but doable if there is a strong request from the community.
For the custom nodes it would be really nice indeed to have that.
The way I see this as a possibility in the future : a third party will create the custom node on Dynamo and then will have to create the node UI representation in Dynamo Player ( using some Dynamo Player API which doesn’t exist yet ). So the third party will have control over the DB level of the node and also over node UI representation in Dynamo Player.
Good news is that things are designed internally to make this possible in the future.
However , since this still requires a significant development effort we need to have a strong request from the community so that decision factors prioritize this accordingly. So please tweet about it on every occasion !

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+
