Cut with void only in fine and medium detail

albertopola — Sat, 21 Oct 2017 13:16:13 GMT

Ho everyone

I would like to create a family with 2 voids. One of the void will always cut the host and the other void will cut host only in fine and medium detail.

Is it possible?

Thanks everyone

How about 2 sets of host and void, one for coarse, one for medium and fine?

Ditto @ToanDN

Or, 2 nested families; a 1-void family, and a 2-void family nested into a host family and assigned the appropriate visibility based on the Detail Level of the view.

Or, don’t have the model visible in a Course view at all. Instead, have a simple 2D “symbolic” representation for Plan and Elevation views.

I try to create a wall-based door family with 2 nested wall-based family in which there is a void. I cut the void in the nested family. When I assign the visibility to each nested family, they cut the wall of the door family and in the project the wall is cutted by both of the nested void.

The family should only have one void (or opening) to cut the wall in the project. If you're using nested components, put it in the host family and parameterize it so it will flex (height and width) to make the wall opening you need for the door type.

But, I don't understand how this relates to how much detail will be displayed (made visible) at each Detail Level. A 2868 door type is is still a 2868 door type in Course and Medium and Fine views.

If you want to upload the host family (with the nested families); that would probably be the best way to explain your issue. We can then better advise you.

Voids don't have visibility properties. They are there, or they are not, no in between.

You need to approach this from the other side. Create the largest void, and fill the wall with different masses for different detail-modes.

Unfortunately in standard families, you cannot join the infill with the wall, so you get separation lines between the wall and infill.

There is a trick however that might get you the result you're after.

Create a shared Wall family using this post (https://forums.autodesk.com/t5/revit-architecture-forum/model-in-place-component-convert-to-family-component/td-p/3363531). Nest this wall family in your door / window family and make sure that the material of the wall (in the project) and of the mass in the wall-family are the same. The nested family mass visibility can be regulated by Visibility Settings.

See example family (Revit2017)

@albertopola: if you don't mind, I'd love to see your door family (the rfa) that uses this method. I can't quite wrap my brain around it conceptually. Old age, I suppose. Ha!
