How to find the family inside the Room of revit project link

This Post is show you how to get link elements , find Geometry intersection pairs and set the parameter of elements.

For the lager project that split the different part of link revit project would be very useful.

 

First you need to operating the Dynamo on Fmaily side Project, because the parameter need to be editable.

And following Package need.

1.Steam Node (1.0.0)

2.Clockwork for Dynamo 1.x (1.0.2)

Basic Workflow :

  1. Get the link room geometry and family location point.
  2. Check Geometry intersect with family location point.
  3. Filter the intersetion and get the “Room Name”.
  4. Get room information and set parameter to family parameter “Mark”.
  5. Family Parameter “Mark” will fill with the correct “Room Name” where the family location is.

Workflow: Create Structural Framing Opening for Horizontal Ducts from a linked file in Revit 2016 using Dynamo 0.9.2

In our previous tutorial Create Structural Framing Opening for Horizontal Ducts in Revit 2016 using Dynamo 0.9.2 we saw how to create openings for ductwork in structural framing which coexist in the same file.
In today’s tutorial I have created another workflow and I will show how to create the openings but with the ductwork file inserted in the structure file as a link.
First we will use the Python Script node to get all the ducts elements from the link then we will pass those elements to the “Geometry.Intersects” Node. The intersection between two geometries is another geometry so we need to allocate the center of the intersection geometry thus we use the “Solid.Centroid” Node.
After we will got the intersection points we shall identify the duct and the beam that create each successful intersection.
Once we have the beam corresponding to each duct we will use a plane that is parallel to the beam and centered in the intersection point to get the boundaries of the intersection by get the intersection between the plane and the duct. As now we have the boundaries we can create the opening from them.

Workflow: Create Structural Framing Opening for Horizontal Ducts in Revit 2016 using Dynamo 0.9.2

Updated:

Hello folks

It’s been a long time since my last post. Today we will use a new technique to get the intersection polygons between Structural Framing and Ducts in Revit using Dynamo.

This topic has been inspired by Matt Wash and we will use the Location Curve property of Line Based families to get the plane at which the intersection points exist. Then we will use this plane to get the intersection polygon from the Ducts.

As we have the polygons we can pass it to the Python script node to let the magic begin.

Workflow: Import Geometry to Dynamo from CAD Link

I had a simple question recently: How do I get some DWG or DXF geometry into Dynamo to do some simple tasks, like placing families at points in Revit?

I looked for the DWG import nodes, until I realised they only come with Dynamo Studio. Then I realised that Dynamo Studio doesn’t run on top of Revit. Weird, huh?

Then, I came across this little offhand comment from John Pierson:
You can import in Revit> select file> and query geometry.

It can’t be that easy, can it? Yes, it can!

Just like this:

So, by simple selecting the Link or Import element in Revit, we can use Element.Geometry to unpack its geometry. This method would likely work with any other CAD format that Revit can Link or Import, such as SAT, SKP or DGN.

I had tried some more challenging workarounds like going via Flux, but sometimes the easiest option is the best.

Workflow: Create Rectangular Wall Opening for Horizontal Pipes from a linked file in Revit 2016 using Dynamo 0.9.2

In our previous tutorials we showed how to:
The workflow assumed that the model contains all trades in one file. But most of cases each trade exists in its own file and based on the linking technique used in your firm the relation between the trades projects defers.
In this example I assumed that the architecture linked the piping file to the base model project, because most of cases the architect will be the responsible for making the opening in the walls of his model.
Nothing changed from the Create Rectangular Wall Opening for Horizontal Pipes in Revit 2016 using Dynamo tutorial except the technique of getting the pipe elements. In the previous tutorials we addressing the pipe elements directly from the current model, but now we will access them through the Link file.
The “Get all Pipes from link” Node is pure Python Script that get the link documents from the current project then collect the Pipes Category and set them as its output. The workflow then continues as it is in the Create Rectangular Wall Opening for Horizontal Pipes in Revit 2016 using Dynamo tutorial.

Create Rectangular Wall Opening for Horizontal Pipes in Revit 2016 using Dynam 0.9.2

First of all thanks for all the fans for the reviews, comments and following up. This topic is prepared as a special request for my followers on LinkedIn, DynamoNodes and Facebook.
In our previous tutorials we showed how to:
In today’s tutorial we will make a little tweak for the Create Wall Opening for Cable Tray in Revit 2016 using Dynamo workflow to perform the rectangular wall opening for horizontal pipes.
The example will use the Revit’s standard rectangular wall opening. Depending on the radius of the pipe the width and height of the opening will be set.

Workflow: Create Floor Opening for Vertical Pipes in Revit 2016 using Dynam 0.9.2

As we saw in the previous lessons Create Wall Opening for Cable Tray in Revit 2016 using Dynamo and Create Wall Opening for Ductwork in Revit 2016 using Dynamo it is possible to make opening in Walls for cable trays and ductwork in Revit 2016 using Dynamo.
In today’s lesson we will see how to make openings for Pipes but this time in Floors. All you want to do is to select the Pipes Category and the Floors Category.
Dynamo should determines the intersection surfaces and hence the edges of the surfaces.
We choose in this example to make circular openings.
To control the diameter of the circular opening an offset from the intersection curves shall be done.
Once we determined the radius we can let the Python Script do the rest of the magic.

Workflow: Create Wall Opening for Cable Tray in Revit 2016 using Dynamo

In the previous lesson Create Wall Opening for Ductwork in Revit 2016 using Dynamo we saw how to create wall openings for ductwork in a project. In today’s lesson we will do the same exercise but this time for cable trays.
First we get all the wall elements and the cable tray elements in the project then get the intersection points between them. As we got the intersection points we need to determine the direction at which the opening shall be placed.
One important point that has bee raised from one of the page’s fans yesterday was that the size of the opening is constant, so now by adjusting the “Size Factor” Node we can control the size of the opening as a function in the dimensions of the cable tray (or duct).
The Revit API and hence Dynamo are using the Feet as its standard measuring units, so in some cases we need to correct the units by multiplying the lengths by conversion factor.
In our case the Revit project units are in mm so I multiplied the lengths came from the Dynamo calculations by 304.8 to convert from Feet to mm.
At the end by using the Python code block we make the magic happen.

Workflow: Create Wall Opening for Ductwork in Revit 2016 using Dynamo

Hi folks!
Have you ever in Revit find it so tedious to track all the clash points between different disciplines and the architecture elements to address them.
Now with Dynamo you can do it so easy. Today’s workflow shows how to find the intersection points between ducts and the walls then using a simple python script we can add the wall opening in the proper position with an arbitrary width and height.
The image of the workflow may not be so clear so I’ll attach the dyn file.
