Image Image

Image Dynamo is a visual programming tool that aims to be accessible to both non-programmers and programmers alike. It gives users the ability to visually script behavior, define custom pieces of logic, and script using various textual programming languages.

Create a Node Library for Dynamo

If you're interested in developing a Node library for Dynamo, the easiest place to start is by browsing the DynamoSamples.
These samples use the Dynamo NuGet packages which can be installed using the NuGet package manager in Visual Studio. NuGet
The API Changes document explains changes made to the Dynamo API with every version.

You can learn more about developing libraries for Dynamo on the Dynamo wiki.

Build Dynamo from Source

You will need the following to build Dynamo:

Directions for building Dynamo on other platforms (e.g. Linux or OS X) can be found here.

Contribute

Dynamo is an open-source project and would be nothing without its community. You can make suggestions or track and submit bugs via Github issues. You can submit your own code to the Dynamo project via a Github pull request.

Releases

0.9.1

Dynamo Core

  • Direct manipulation: Sometimes numerical manipulation isn’t the right approach. Now you can manually push and pull Point geometry when in navigating in the background 3d preview.
  • Freeze Functionality: When you have long running portions of your graph, or don’t want to export data to other applications, or want to debug some logic, don’t unplug your nodes. Now you can suspend execution of specified nodes in the graph by using Freeze in the right-click contextual menu
  • Search Enhancements: Only look at the node libraries you want to with new filtering tools. See more options at once by using a compact view, or get more information with the detail view.
  • Zoom re-center: Select a node, then zoom and recenter your orbit on it in the 3d Preview Navigation
  • CNtrl-drag: Copy/Paste nodes in a familiar way
  • Add comments to custom node inputs and full default states for complex data types
  • More forgiving DesignScript syntax: Users can now write instance methods (ex. MyCurve.PointAtParameter(0.5)) as Static Methods (ex. - Curve.PointAtParameter(MyCurve, 0.5))

Known issues

  • No backwards compatibility with 0.9.0 and before

Dynamo Studio

  • Share your work online: Share interactive parametric models online. Just publish your Dynamo graph and send a link to your colleagues or the whole world. People can view and interact with your designs in a regular web browser with no Dynamo installed
  • ImportExport: Read directly from DWG files and only pull out those pieces of the file that you want.

Known issues

  • Customizer not using Display.SurfaceGeometry

Dynamo for Revit

  • Batch placement of adaptive components : Huge improvements to the speed and reliability of placing large numbers of adaptive components.

Known issues:

  • In some situations, placement of Adaptive components requires a change in list structure. The AC placement nodes now expect to receive lists of lists of placement coordinates. In the past, the nodes expected to only place one AC, now it expects to place many. If you are going to only place a single component, it needs to be nesting into a list.

0.9.0

Create DirectShape Elements in Dynamo

  • You can now wrap meshes, solids, and surfaces in a DirectShape and place it into your Revit Model

Library Enhancements

  • The library is now organized in a tree view to make it easier to find the nodes you want. Node types have also been color-coded to make it easier for you to locate create, action, and query nodes in the library

Manage Custom Node and Package Paths

  • Add paths to makes nodes and packages show up in the library

Node Layout Cleanup Improvements

  • Clean up layouts considering groups as a whole or clean up layouts within groups

Background Preview works on Remote Desktop and Parallels

  • For remote systems with GPUs and virtual machines with hardware-acceleration, background preview is now visible.

Additional Updates and Improvements

  • New Chapters and expansion of the Dynamo Primer
  • Easier to read Search Results
  • Node to Code Stabilization
  • Improved 'Canvas Snapshot' functionality
  • Move to .NET 4.5
  • Lots of bug fixes

0.8.2

Local Network Package and Definition location

  • use a common shared network folder within an office environment.

Preset Graph States

  • Keep track of different states of your graph and develop design options with Presets, found in the Edit menu

Color on surfaces

  • Square arrays of color can now be applied to surfaces with the Display.BySurfaceColors node

Node2Code

  • Select groups of nodes and automatically create Code Block Nodes from the selection
  • Known issues that we will continue to work on

Search/Browse

  • Tooltips and search algorithm improvements for in canvas search (via right click)

Localization

  • Now localized to 12 languages (Dynamo for Revit and Dynamo standalone)
  • Define the localization for Dynamo standalone Instructions here

Documentation

Command Line Interface

  • DynamoCLI now available for executing non-Revit Dynamo graphs

Package Manager

  • Publish a package locally from Dynamo for Revit

Known Issues

0.8.1

New Graphics pipeline

Graph Management

Excel

  • Improved handling of Excel.Read, including more robust management of null values and ragged lists
  • Excel.Read now has a ReadFromFileAsString toggle, to preserve text imputs if desired
  • Excel.Write now has the option to completely overwrite data in a sheet, or only the affected cells
  • Excel.Write ignores popup messages

Lists

  • List.Transpose now keeps indices of lists consistent
  • List.Clean removes null and empty lists from a given list, with or without preserving indices
  • IF nodes will now lace over test input. Example, list with inputs {true, false, true}, {1,2,3}, {a,b,c} will result in {1,b,3}. Previously, result would be {{1,2,3},{a,b,c},{1,2,3}}. See submission https://github.com/DynamoDS/Dynamo/pull/4464

Revit

  • FamilyInstance.SetRotation node

Localization

  • Dynamo for Revit is now localized based on the Operating System locale.

For instance, Point.ByCoordinates in a Code Block Node was affected by a collision with a Point. operation in the popular Rhynamo package and would throw an error saying “Warning: Dereferencing a non-pointer. Dereferencing a non-pointer.”

Hardware Acceleration in Revit 2015

  • Hardware Acceleration was turned off when running in Revit 2015. Graphic speed and clarity is greatly improved

Instrumentation

Dynamo contains an instrumentation system that anonymously reports usage data to the Dynamo team. This data will be used to enhance the usability of the product. Aggregated summaries of the data will be shared back with the Dynamo community.

An example of the data communicated is:

"DateTime: 2013-08-22 19:17:21, AppIdent: Dynamo, Tag: Heartbeat-Uptime-s, Data: MTMxMjQxLjY3MzAyMDg=, Priority: Info, SessionID: 3fd39f21-1c3f-4cf3-8cdd-f46ca5dde636, UserID: 2ac95f29-a912-49a8-8fb5-e2d287683d94"

The Data is Base64 encoded. For example, the data field above ('MTMxMjQxLjY3MzAyMDg=') decodes to: '131241.6730208' This represents the number of seconds that the instance of Dynamo has been running.

The UserID is randomly generated when the application is first run. The SessionID is randomly generated each time Dynamo is opened.
