How to cut out forms in Group family roof?

Greetings,

 

Is it possible to cut out forms like that, without breaking "roof group family"?

I tried "Void forms" but they are not making any cuts?

Instead of doing you Roof Cladding as a loadable family, you can do the same thing even better in the Project as a Sloped Glazing Roof.

I checked "Sloped Glazing Roof", as i looked in tutorials it's not what I'm looking for, since i have all roof structure already made, I need only make cuttings in roof.

Thanks for recommendation tho.

 

ps I'm using pre made roof because it has all documentations and structural schemes.

Don't have Revit at the moment so I can't see your file.

 

1. If it is a generic model family the use another generic model family with solid, not void, to cut it using cut geometry, or join geometry and hide the other.

 

2. If it is another category family, add the void directly in the family and use dimension parameters to locate/size the void to cut or not cut the solid. Meaning, if the void intersects the solid then it cuts, if the void is outside of the solid then it doesn't cut.

 

3. In the long run, it is better to use roof tool in project instead of a family and you have a host of modifier tools to work with such as former, opening by face, vertical opening, shaft, roof join.

Well, might be worth reconsidering. Consider the BIM value too.

You only need a Void ... modeled in a Face based generic Model 

For the added BIM Value and if quantification is required...you can set the nested standing seam panels to shared ... then you can schedule their quantities and dimensions (assuming that the latter are shared parameters)

An Alternative method you can use without Voids or cuts or shared families is Convert the Standing Seam Roof Generic Model Family to Parts ... This will allow you to

  1. Treat each panel individually using Shape handles
  2. Splitting and excluding parts of the panel at the intersections with walls
  3. Quantify the panels using Parts schedule
  4. Get the cut pieces measurements from the excluded parts

See GIF below:

Hello,

Yes that's 2nd solution is what I was looking for for this roof.

I don't understand why I can't "Divide parts", what I'm missing?

And will be there a way to group them back together later?

There are not much tutorials about "Sloped Glazing", but anyways will look into it for future CAD functional.

  1. Make sure the right workplane is set (the Standing Seam plane)
  2. (On the outer side) Pick the edge of the wall from the outside
  3. (On the inner side ) Pick the inner side of the SS Panel then drag the sketch line slightly outside the panel
  4. At the top Pick the edge of the Panels you dragged up
  5. the bottom simply pick the edge of the panel and drag the sketch slightly outside the panel
  6. connect the ends around the wall using pick line

When the division is done properly you will see the sketch lines turn green when you exit sketch mode

Do not group them,,, Once done >> Isolate category >> select all except the excluded parts and Assemble them See GIF below

Divide Parts at Intersecting Level and then Exclude Parts to remove the ones at the opening.

I just noticed it's only making changes to roof made in certain view, if it was edited in 3D then changes only applies to certain 3D view?

That's how it's supposed to work? 

I need to edit every view?

Yes ...On the view properties palette select show parts. That is how parts work...it is a view mode, you do not edit every view, you set up a view template for those views where you need to show parts...

Yes, I didn't notice that some how my "Constraints" base level was not Associated, I set it to any level to match warplane, and it's fixed allMissing.png
