Halftone not working for surface pattern in masses

[agueda_contreras_garcia]

I am working on a 3D view in Revit 24 and when I set to "Halftone" in the Visibility Graphics the Masses and Generic Models I get this result:

Apparently all Lines are Halftoned for both GM and Masses, but the Surface Pattern of the Masses isn't.

I also tried with a filter and it's the same result only the lines of the Masses it's halftoned. 

My workarround was to set the Surface Pattern Color of the Masses the same as the "halftoned color" of the GM, but is this a normal behavior of Revit or is there something not working correctly in the model?

It is not clear what is defined under the graphics tab of the materials you are using but to my knowledge Halftone does not apply to solid fills...Instead of messing up the material I would suggest applying a filter to override the surface patterns color of both

[agueda_contreras_garcia]

What is defined is this:

Same filter for both elements, in both the "Halftone" works for the Lines (grey now instead of black) but for the Surface Pattern, in the GM the color changes and gets halftoned, but in the masses not.

Your suggestion it's what I did to solve the problem for now, apply different colors in both elements. But I would like to know if this is a normal behavior (only surface pattern in masses can't be halftoned).

@agueda_contreras_garcia  Unless I am missing out on something or there is some particular view or visibility setting which you have tweaked and forgot to mention, using a filter seems to work fine at my end using one color

I suggest you try changing the view template category to Halftone, or better yet, change the Halftone material color.

That's why I asked, because I can't find the reason why it's different. There is no view or visibility setting tweaked (as far as I can see)

[RDAOU]

maybe because they are not actual masses but imported objects?  Did you create these using Rhino or Forma? and which format did you use? (Try SAT or AXM)

@RDAOU right,so draw them manually :

as @RDAOU mentioned, it's an import from Forma, with a Direct Link. So the idea it's to save time, and to re-model everything it's not an option

but thanks for your answer

this is not too much ,half an hour or something!!

 I left the office so I wasn’t able to follow up…I think there might be an easy way to fix without remodeling. one question though, do the masses need to be individual masses one for each building? Or can they all be in one mass?

[agueda_contreras_garcia]

they can all be in one mass

I tried to replicate the issue on my end but wasn’t able to reproduce it. Please see the GIF below for reference. I’ve tested with nearly all element types in Forma, and the linked proposal works correctly with the filters, based on the link settings I’ve applied. 

I’m wondering if the issue might be related to the types of elements used in Forma (e.g., Basic Building vs 3D Sketch Building)or the Link Options in Revit

The plugin is still in Beta, so I'm not sure if that's contributing to the issue. However, a workaround that might help is to export the proposal from Forma as an OBJ file and use that instead. For a finer finish and more consistent categorization, I would suggest...

• open the .OBJ in FormitPro 
• re-export as .AXM 
• Import the .axm  into Revit as either a generic or a mass
• re-update the Forma

If you do not have Formit, you can try to isolate the category of the Masses in Revit and Export those to STL or OBJ >>> Delete the ones in the current group >>> imprt either the STL or OBJ as a generic model. (In this case you wont need the filters, you would simple override the Category or Subcategory in Visibility graphics)

[agueda_contreras_garcia]

I didn't model the volumes in Forma, I used one of the free packages for buildings there are available:

So indeed it can be either the way was modeled in first place or the Beta plugin.

For now having two different filters (one for masses and another one for generic models) was a workarround that is working to avoid any extra work remodeling or reimporting. But I'll try your suggestion next time I have to import from Forma.

Thanks!
