Rhino to Revit via Spring Nodes/Dynamo Cut Hatch Issue

[thompsonburry]

[FONT=Helvetica]Hi all,[/FONT]
[FONT=Helvetica]I am new to the forum, dynamo and revit. I am a student and primarily a rhino/grasshopper user. I have been interested in organizing an effective rhino to revit workflow where I can use rhino to model geometry and revit as a documentation tool. I have been using spring nodes via dynamo to import rhino geometry into revit somewhat effectively. However, I am getting inconsistent cut patterns from the geometry. Has anyone experienced this issue? Attached are two screen captures showing examples of the problem i am having. In the screen captures you can see a section box showing a proper earth cut pattern, then when the section box is moved the cut pattern disappears. This is occurring throughout the project as the graphics will show correct fill settings in certain sections but not in plan view(or other sections). The issue seems to be geometry specific as it only occurs within hyper-complex solids from rhino. I am only editing the objects by assigning them materials within object styles in an attempt to rapidly modify the geometry within all views. Any suggestions would be greatly appreciated.

[FONT=Helvetica]In this image i have highlighted one of the solids i am having difficulty with. As you can see the solid does not have a cut pattern displayed. However it was treated with the same object styles as the earth poche below it.

[FONT=Helvetica]The image below shows the same object from a different perspective. It is being rendered within the revit viewport as if it isn't solid, you can literally see into the object.

[FONT=Helvetica]The final attached image shows the same geometry within the same 3d view however in this image the section box was adjusted and pulled away slightly. As you can see the object is now being rendered within the viewport as a solid with proper cut plane hatch assigned.

[FONT=Helvetica]I have found this issue to be present with several of the geometries i am attempting to document within revit.[/FONT][FONT=Helvetica]I have attempted the same process with several other rhino models and have gotten the same results within one or two solids within each 3d model. I apologize to everyone if this is more of a revit problem than a dynamo one. I was hoping that because spring nodes is discussed in this forum that someone else may have run into this problem previously. Please let me know if further explanation is needed.[/FONT]

You might have more luck in our Dynamo sub-forum, which gets a bit more traffic these days...

I'm more than happy to move the thread if you wish (please don't post another) but let's maybe wait and see first?

Otherwise I would love to assist, but my adventures in Dynamo are rudimentary to say the least!

Welcome to the forum!

Hi @snowyweston

Thanks for the welcome. I submitted this topic to the Dynamo Bim Forum. They are telling me this is more of a revit issue than a dynamo one.
Here is the link to that discussion. https://forum.dynamobim.com/t/rhino-...roblem/5421/12

I am still having issues getting the imported geometry to display cut hatches properly regardless of the family I import them into. Im going to attempt to introduce a middle man between rhino and dynamo, something like fusion or autocad. If anyone else has any other ideas please let me know.

Thanks!

Anybody have any ideas?

Hi @thompsonburry

Have you had a look at Flux for your data transfer. https://flux.io/

At AU Sydney last week, there was a very interesting talk by a developer regarding an issue relating to Rhino Breps into Revit and Flux was the answer.
I have not tried it but it looks very interesting.

Barry.

@Barry Mair

I have tried using flux earlier. It is an amazing program for importing some things from rhino into dynamo however when dealing with nurbs solids it doesn't seem to work very well. Do you know if this discussion was recorded/available online somewhere?

@thompsonburry

I have been checking on the AU recordings as they were going to be available. Not as yet!
I will let you know if I spot them.
Unfortunately it was a developer that I have not been involved with - it might be a good reason set up a coffee networking session.
I am interested in learning the process for my own works.

@Barry Mair

I opened up a conversation within the flux community, hopefully we can get some answers there
https://community.flux.io/questions/...-to-revit.html I have had success with meshes and single surfaces, but no nurbs solids yet.

If you are interested in the spring nodes workflow here is the video tutorial i used to get to where I am so far. At around the 25 min mark they start discussion the rhino to revit workflow.

Hi

I am facing the same problem myself in 2020! Did you have any luck finding a solution?
