ACIS Import not showing up when imported into revit mass

Anonymous — Thu, 26 Apr 2018 03:07:03 GMT

Hi,

I am trying to import a facade made with rhino and grasshopper into revit. Every time I try to import the ACIS file of the facade surface nothing shows up. I have tried rebuilding the surface multiple times in various different ways with no luck. I have tried making the facade a solid rather than a surface but still not much luck there. I have also tried splitting the surface into smaller segments again no luck there. Sometimes it does come when its a solid but have of the surfaces seem to be missing. All the revit settings have mass turned on. Any help or leads are appreciated. I have attached the rhino and ACIS files.

Your first sat won't import in for me, but your second one ("solid") does. R2018.2

@barthbradley It shows up for me as well but the rectangular cut outs only show two surfaces and the other two look like its in wireframe view if that makes sense rather than it looking like a solid with the rectangles punched out. Is that the same for you? Ive attached an image showing mine.

I have no idea what it is supposed to look like, but this is what I see.

Are you sure you are not just seeing though the mass. You need to apply a material to it.

It is supposed to be a solid panel with rectangular holes punched through like this.

Can you work with Revit? This screen can be done in Revit as a Curtain wall in 2 minutes.

p/s: guys like @barthbradley will try to prove me wrong by getting it done in under 1 minute mark

@barthbradleyI have changed the material under the object styles menu but am still getting the same visual result. I am not seeing a material parameter when i go into edit mass and click on the imported mass unless im missing something?

@ToanDN I can work with revit. Definitely open to doing it in revit if you have a good way. It might not be clear from the pictures but the holes to get smaller as they approach one side of the facade which is why i used grasshopper.

You apply a material TO the faces of mass. This one's a booger though. You got a lot of faces!

....to quickly see what I mean, open your paint tool and pick on some faces with it. Voila! Paint material applied. But, of course, I'm not advocating you do this; just trying to explain the concept.

Besides using the paintbrush is there a way to apply a material to the mass? Even with the paintbrush revit wont let me select certain faces to put a material on and they are left transparent.

Sorry, but like I said: there are a lot of faces; maybe too many faces for Revit to compute. It happens. If you need this in Revit, you may need to build it in Revit.

Gotcha. Thanks for the help.

I think you need to edit the model in Rhino or Grasshopper and "flip normal", if you know what I mean.

This can be done in Revit--
