Unconstrain #Revit Walls with #DynamoBIM

A coworker of mine recently had a need to unconstrain a lot of walls in his Revit model. Naturally, we turn to Dynamo to get this done. Initially we thought it would be as easy as assigning "Top Constraint" as nothing or unconstrained. Wrong! It turns out, if you want to unconstrain a wall's top, you simply set the value to the wall element. Check it out in the video below!

First I demonstrate what I tried at first, then I show the solution.     Have fun and be in awe of the mysteries of Dynamo!

Get #Revit Beam System Members with #DynamoBIM

A question came up at my firm recently regarding how to quantify the amount of beams a beam system contains in Revit. Currently, this is not easily accessible through the UI, but luckily there is an API method for obtaining the members of the system.

This is where Dynamo and python come into play.

This node is now in Rhythm, enjoy!

#Revit Space and Room Tag Host with #DynamoBIM

Recently I was talking with Marcello on the Simply Complex Podcast about the lack of annotation nodes in Dynamo. After a question also came up on the Dynamo forums, I decided to add these two useful nodes to Rhythm.

This enables us to do some fun stuff based on the tag elements now! And yes, these are made with Python!

#DynamoBIM, What The Node?!?

The question of where a custom node comes from comes up on the forums pretty often, so I figured it was time for a solution. Well thanks to dynamonodes.com we now have an index for most packages available on the package manager.

My #AU2016 Proposals Right Now

I saw a few other people share their proposals with everyone and I have only done so on twitter so far. So here they are.

And here are the videos I made to promote them.

• Manage Your Revit Model, with Dynamo!
• Rhino Can Do Random, Can Revit Do That Too?
• Stretch First! Exciting Methods to Make Your Revit Families Stretch and Flex

I have a few more in my back pocket that I want to get in before the deadline on May 27th.

Any suggestions on anything else you all want to see, send me a message!
