Rhino / Grasshopper to Revit

Help
1

Hi there,

Just trying a simple setup here to transfer data from Rhino / Grasshopper into Revit.
its a simple model, a structural grid for now, columns and beams.

Did a rhino inside revit version that works quite well.
The result is like the image below.

My problem is that i cannot do the same with speckle.
While trying to do the same with speckle as detailed below i get an error in revit. (this is just the first level columns).

Error in Revit is that
”Objects failed to bake due to a fatal error!
This is likely due to scaling issues - please ensure you’ve set the correct units on your objects or remove any invalid objects.

Revit error: Change Offset Value so that Column height is not 0.0.”

Speckle stream with the data is:

Maybe i did not setup a parameter propperly but did not come accros any kind of documentation for that.

Thanks for any help.

Hey @Ionut_Anton !

I think the parameters field does not currently support values that are Elements…
I’ll double check the code, but probably the easiest fix for now is for us to add a Top Level input to the Slanted Wall component.

P.S.
Parementer names should be inputted either:

  • exactly how they appear in the UI eg. Top Level
  • or with their Revit BuiltInParameterName

Hi there,

Problem is the script does not work at all, with the toplevel or without.
and toplevel is not the only parameter i want to work with.
I would like to add a baseOffset adn topOffset so how do i add these parameters to the column component?

Cheers

For base and top offset you can just use:

Base Offset and Top Offset as input parameter names, I’ll try put together a quick working example later!

Hi there,

Gave it another shot.
Looks like beams i can send succesfully with parameters.
stream for beams test branch: Speckle

But unfortunately colums i still get the same error from speckle when receiving the stream:
”Objects failed to bake due to a fatal error!
This is likely due to scaling issues - please ensure you’ve set the correct units on your objects or remove any invalid objects.

Revit error: Change Offset Value so that Column height is not 0.0.”

Stream for columns branch: Speckle

And the grasshopper script for columns looks like this.

i cannot send columns without a level.

Please advise.

Hey @Ionut_Anton !
Apologies I forgot to get back to you, next time you should ping me :wink:

Here’s what I would do to create columns:

Note that:

  • I’m using the Level by Name node, this is recommended if you already have set up levels in Revit
  • I’m using the RevitColumn Vertical node, since I noticed all your columns are vertical (and this has inputs for top-level too)
  • I’m inputting the stream from a URL, saves a bunch of nodes
  • the input offset is in meters, since the Rhino document is in meters, while the Revit document is in mm

Let me know if it works, gh file attached!

PS
I just noticed the RevitColumn Slanted is not working as expected! I’ll look into it.

Great. thank you.
didnt realize there was another type of column node.

Cheers.

Quick update, I’ve fixed the slanted clomuns (structural columns in Revit).
For these, you don’t need to specify a top/bottom offset or top level, as they are automatically inferred by the position of the baseline endpoints.

Any other issues/questions just let us know!

Sample usage:

Hi there,
now vertical columns work like a charm.

The only thing that mislead me was that vertical columns are in the Architecture tab in Speckle 2 Revit and not in the Structure tab. And both read in Revit as Structural columns.

Thank you.

Oh! Thanks for that suggestion! We’ll move it to Structure since it makes more sense for it to live there. :+1:t3:

I am running into the same problem as @Ionut_Anton,

And i tried the simple example as well, but I am still getting the error?

I placed one column by hand, to check the Family and Type. I also tried to flip the input curves (maybe they are upside down).

Hey @Joelmick we have fixed the slanted columns but have not released a new version of the connector yet.
You can expect it early next week, otherwise, let me know if you’d like a beta release and I’ll make it for you :slight_smile:

A beta release would be great, thanks!

That’s ready for you to grab, please install both revit and gh, and let me know how it goes!

Awesome, it works perfectly now!
