Window Host and Geometry

I am creating several custom window assemblies from a rhino file. I am having two conflicting problems. In the attached files I isolated the revit, rft, rhino and grasshopper and I get the error “Parameter Width has an invalid value. {324367}” in the New Component Family component. I am still able to create an instance of the family with the Add Component (Location) component but it comes in without any of the geometry, just like a blank window template. I would appreciate help with this issue.

The bonus issue, is that in my main revit file where I was using the same rhino file, same grasshopper script, same rft I was able to create a window family with the geometry, but it would not host to a wall, only floors and it would not make an opening presumably because it was only hosting to floors. The New Component Family component is highlighted Orange with an error “No suitable host object is been found”

Hi @gordonleibowitz

The reason you are getting that error because by default window family template has width parameter or Label.

In the following i have selected the wall based family template and change the category to window.

You might wanna check this if you want to link your parameters inside the Family.

I think I understand, because the window rft has a bunch of built parameters (in this case the width of the opening width) the family doesn’t know what to make because something is conflicting with the built in parameters. Using the generic wall based rft works because it doesn’t have those prebuilt parameters.
