New Revit nodes in v1.2.3 daily builds

Hi All,

We are getting ready for a 1.3 release, and we have a number of new functionalities that we would appreciate your feedback on. Here is a draft list of what’s going in, please take a look at the latest builds available at

Large number geometry scaling: For folks who have had trouble with geometric precision in models with large numbers (buildings and landscape projects described in mm), there is a solution that adjusts numerical precision to accomodate these large numbers. Check out the Geometry Scaling section in the Settings menu.

Isolate geom preview: When the mode is enabled, only selected nodes will have their corresponding geometries displayed in full opacity. Geometries that correspond to unselected nodes will be displayed transparent with 10% opacity for meshes and 20% opacity for lines and points.

Dynamo Dictionary Access from context menu: A link to Dynamo Dictionary is added at the bottom of help menu popup window. This is available for the out-of-the-box core Dynamo nodes. Next phase will include Revit nodes

Preview Bubbles enabled for Revit Selection nodes

Multi-output port re-connect feature using Shift+Left-Click

Fixed line break issue in for group titles, increased group titles font size

@john_pierson Ah, looks like this is in the Master branch, but not yet in this branch leading to 1.3. Stay tuned.

Ok, isolate in daily builds now. Also Global Params!

*Begins to frantically close Revit and Dynamo. Then heads to :grin:

Global params aren’t quite in the latest build yet. Thought I would let you guys know.

I was just using it . . . what version of Revit are you in?

Ah, that’s interesting. I was in 2016 and it does not show up in that version.

Hi @john_pierson

Global Parameters were introduced in Revit v2016 R2, and then improved in v2017.

Are you using Revit 2016 R2?

Global Parameters API was fully implemented in R2017.


@john_pierson Isolate Preview Geometry now available in the latest daily build of 1.2.3, please try and let us know your feedback.

Awesome! I plan on writing a full review. :smile:

Hey John, have you had a chance to try the FamilyType.ByGeometry? I’ve seen a strange lag in getting my Dynamo control back, although the operation is completed in Revit. But only reproduces on my machine, not on others in development.

It seems to run as expected for me.

Is there any known Incompatibility of the current build of 1.2.3 with Dynamo Studio installed?

Nope, I’m using just such a combination myself. What are you seeing? When we release, the suggested upgrade path will include a Studio specific patch from the Autodesk Desktop App

When installing the current Build, DS will not start, Un installed and Reverted to 1.2 and DS works again.
