What Dynamo Needs?

So having dabbled in Dynamo on an off for the best part of the year, I am in no position to greatly comment on what Dynamo needs. It is a complex animal and seems you need a good bit of Python to tweak what is on offer. There is a good smattering of custom packages out there that can really aid in productivity and open avenues within Revit that were seemly impossible to do.

 

From newbie with no virtual computational experience, to having created a number of successful graphs either interoperating with Rhino and adaptive components, placing complex railings equidistant over a curved floor perimeter, or generating site plans with Open Street Map data, I am now in a position of understanding, yet having frustrations both at the same time.

 

It is a great feeling to nerd out and get a graph to function, minimizing the nodes and playing with Dynamo’s logic. It is frustrating to see those little yellow error messages appear without explaining very much, or that the definition seemingly works, only to find out the next time you run it, it inexplicably doesn’t; trying to locate that node to do something simple or that the Revit API isn’t exposing itself.

Arghh! Those error message, deprecations and unresolved statuses

 

My colleague Dane Stokes, a Grasshopper whizz and Rhino jockey, gets easily frustrated with Dynamo. He likens Dynamo to a British car: finicky, powerful but good luck getting it started and seemingly in the shop most days. 

The functionality and polish of Grasshopper attract many graduates, who typically aren’t constrained to producing construction documentation. Given a choice, most simply gravitate to Rhino and Grasshopper for their needs, leaving few that can aid with Dynamo in the professional setting.

 

Dynamo is a great tool to Revit, but best practices, workflows or documentation have not been developed in industry. The standalone Dynamo Studio is being used with FormIt to create geometric shapes and change their properties. Josh Goldstein at Autodesk has provided tools that generate louvers on a building or create a staircase in FormIt. Yet this added functionality provided by Dynamo already exist in the Revit product with parametric families and tools. So when is it appropriate to implement Dynamo with Revit? What are the best workflows if you are pushing data back into Revit in a Work Shared and live model? How can we share and document our custom graphs that we create?

Dynamo Studio Properties in FormIt

 

Dynamo Player has arrived as of Revit release 2017.1 which helps, but varying inputs need to be incorporated for the Player to function effectively. When we get input functionality, should we create a Dynamo graph or create a dedicated Add-in tool using the Revit API? I feel Dynamo works well for custom situations that require hacking Revit’s stubbornness, yet if there is a repetitive task or a function that is being used consistently on all projects, it is probably wiser to create a tool using the API to share with your entire firm or industry.

I realize that you have read all the way to here and I haven’t addressed what the title of this blog asks, What Dynamo Needs?:

I feel Dynamo would benefit by:

  • Improving search functionality speed.
  • Filtering a list of compatible inputs from an output.
  • Make error messages make sense.
  • A Python debugger.
  • Inputs to Dynamo Player in Revit – akin to the how Dynamo Studio interfaces with FormIt. I have been told by sources that this is coming soon!
  • Dynamo Studio communicating with a headless Revit in the Cloud.
  • Increasing mobility with an iOS application.

 

Kudos by the way to the Dynamo team to having done a great job on the Dynamo Dictionary and the new list level functionality. I look forward to future developments. It is fun to get under the hood!
