The form creation engine in Revit does not really know about flat vertical zero thickness surfaces. However, with DirectShape, we can make almost any type of mesh geometry. One interesting idea coming out of the RTC ANZ event this year was creating these flat surfaces to display grids in 3D. This lets us do things like dimension easily in Navisworks or Revizto. I wanted to use them to add some flat datum lines to a construction setout point family.
Here is the Dynamo Script that I used (Download Make Flat DirectShape From Line):
Basically, you select a Detail (Symbolic) Line and run the script. In action:
Playing around with the lines a bit, I built this geometry for use in the project:
There have been different ways of accomplishing this over the years. Now, with Dynamo, I would use this simple two step process:
- Create a unique type for each Planting or Entourage element (as Height is a Type parameter)
- Randomize a list of values and write them into the Height parameter
It is super easy with Dynamo. Here is how you make the unique types (GUID from Bakery, Duplicate Type from Springs, SetType from Clockwork):
Then, just push the random values in, like this (the Set List node is in Bakery too):
My last attempt at this was here.
Big day yesterday in Revit updates, particularly with Revit 2017 Update 1 bringing some really cool enhancements, and the Dynamo Player! Here are some links and other information:

People have been asking for a way to run their scripts more easily and transparently, and now you can. Simply install Revit 2017 Update 1, ensure you have Dynamo installed, and you will have a new option on your Ribbon…
It comes preconfigured to point at a samples folder:
You can point this at your own “Player” folder containing DYNs.
Press Play button to Run, and Edit button to open the DYN in Dynamo.
It remains to be seen how inputs will be handled?
Pick Objects and Dynamo Player
Interesting thoughts over on the forum, about how if you use a DYN with a Select Node, it will still ‘work’ — this opens up some great possibilities!

I had a good time at RTC back in 2016, it was awesome to catch up with the usual BIM crew and see what they are all up to. Hopefully I’ll get a chance to post in more detail about a few things I learned this time around… but for now, here are my 2016 presentations for you to check out.

Quite a momentous day!

### 1.0.0 ###
– API Stabilization: 1.0.0 is a commitment to stable code that allows for smoother and more reliable movements from one version to another. To more clearly express this, we have been moving to “semantic versioning” to illustrate the nature of changes in each release. We will be using the fairly standard version naming with an x.y.z system, where x incrementing represents breaks to the API (requiring developer refactors), y indicates changes that are still backwards compatible, and z are smaller bug fixes. Package creators and maintainers are encouraged to assess changes to the previous code, which can be found here
– Graphics performance enhancements: see this post for details
– Documentation: Along with new sections of the DynamoPrimer (http://DynamoPrimer.com), we have started an online documentation of the Dynamo API with a searchable index of public API calls for core functionality. This will be expanded to include regular nodes and Revit functionality. http://dynamods.github.io/DynamoAPI/
– Licensing: Dynamo Studio is now using a new version of the Autodesk installer that allows for easier access to network and token flex licensing tools
– Install: we have created a separate installation for “core” Dynamo functionality, those tools used by all implementations of Dynamo, and Revit, and Studio installations. This allows for the sharing of a common core of Dynamo code and packages.
– List Management: Changes to “replication” or automated matching of different data streams in nodes and Code Block nodes eliminates the need for List.Map and List.Combine in many situations
– Send to Web: formerly known as Share Workspace, we have improved the ability to view and interact with Dynamo online with Customizers
– File Export: Users can now author DWG files in the Translation section of Dynamo Studio.
– Direct Shape: Dynamo in Revit 2017 can now take advantage of faster and more sophisticated direct shape creation. In most cases, solid and surface geometry can be sent directly into the Revit environment as smooth (rather than tesselated) surfaces and solids, categorized to whatever is needed. In the cases where a smooth element cannot be created, a tesselated (mesh) object is created, as was the case previously.

For a while here on What Revit Wants, I was a bit worried I was writing about Dynamo too much… “Hey, Dynamo isn’t Revit, its just an addin!”
But guess what?
Now Dynamo is Revit, its right there on the Visual Programming panel, Manage Ribbon.
If you were running Dynamo 0.9.2 prior to installing Revit 2017 (perhaps as part of Building Design Suite Ultimate 2017), you won’t immediately see Dynamo on the Manage Ribbon. After installing Revit 2017, re-run the Dynamo install package, and ensure that Revit 2017 is selected:
Next time you launch Revit 2017, Dynamo should be in its rightful place, right there on the Manage ribbon, ready for you to jump in and start winning.
I put this presentation together about 6 months ago, which is forever in DynamoWorld. But I thought I’d share it anyway, just as a general and basic introduction to Dynamo.

As you are probably aware, when moving from Dynamo 0.9 to 0.9.1 you lose backward compatibility… in other words, you can’t open 0.9.1 files in 0.9 or earlier.
Before taking that step up to 0.9.1 and beyond, you may wish to apply a filename suffix to all of your DYN files, so you are reminded of this issue when you open a DYN. I have a single folder with subfolders containing most of my DYN files, and I added the suffix (082) to all of them at once with this method:
Install Advanced Renamer.
Add the Directory that holds all your dyn files:
Then add a suffix to the filename:
Now, you basically have an inplace backup of files. When you open one of these dyns in 0.9.1 or newer, just remember that you should Save As in Dynamo, and then newly saved file will not be open-able in 0.9 or earlier.
At some point in the future you can then remove or upgrade all of these ‘older’ Dynamo files.
