Revit Family Facade

[Lahoma Jenkins]

Hello,

I am new to the interoperability workflows, and was wondering if I could push a custom facade element that I created in Grasshopper, to Revit as a family (and possibly other tools). I need to communicate geometry as well as some information about the element. Aside from Rhino.Inside, is there a way I could achieve this? How would I go about it if I wanted to create an IFC model of the element, preferably with the help of opensource libraries (eg. xbim)?

Any help would be much appreciated!

Hi everyone, I have been testing different options for importing a complex facade from Rhino to Revit (all volumes consisting of closed polysurfaces). This facade needs to be in the Wall category in Revit and have the possibility to modify type properties. Hence I have made a Wall family for each individual facade and found out that the direct shape is the only option that translates all the geometry from Rhino to Revit without anything missing.

But I would prefer to be able to update the geometry inside the family and add parameters to the Family Type inside the Revit project, without opening the family each time. When I use the New Component Family and Component Family Form nodes the geometry is updated with many gaps. Is there a way to update the family with direct shapes (with material) instead of using the New Component Family node?

Yes I tried that node, it also runs with the same errors of the breps (even though they are all closed polysurfaces) but for some reason the Add DirectShape generates the volumes despite the error messages and the Add DirectShape Types does not generate the facades in Revit

We are now able to simplify the geometry enough and bake it into Revit but then met another issue with the Add Direct Shape Types node. We are not able to see the walls we have added in the project browser and can not create a schedules with the direct shapes. Is there a workaround for this or an issue with direct shapes?

I have been trying to model a facade system for a university assignment, but have reached a point now where I'm struggling to refine the model. This is probably due to my method of creating the model, so I would be really interested to know how I should be working and where I am going wrong.

Inside of the steel frame is a series of tiles which are arranged in varying patterns (Image B) The tile patterns are comprised of one generic model family unit which I have loaded into the project and copied multiple times to create a row. I've then simply copied and stacked the rows vertically before selecting them all to create a group.

Where I'm now having trouble is that I'd like to cut or trim these tile elements to all sit neatly within the steel framing (highlighted blue in Image B) but I am finding that these groups or generic model families aren't directly editable with cut geometry.

Is there a way I can convert or combine my current facade system so the different elements and families are directly editable and able to be cut? Or is it best to start the facade over with a different approach?

I would start this with a curtain wall. Create mullions to match your steel sections. You can replace panels with empty panels if it is open. Create or modify a curtain panel to match your pattern. These will trim neatly to the mullions.
