    Interior gutter and wooden roof

    Hi everyone!

    First post on this forum so be kind please!

    I tried to look for a similar case in other posts but I didn't succed.

    I am currently working on my first project on Revit Architecture: a wooden structure with a simple geometry and ordinary roof.

    My issue is related to the connection between roof and walls as in the attached image (exported from a reference CAD file).

    I was guessing how to model the connection since structural parts (the beam and the x-lam layer) and architectural ones are not alligned.

    Here some of my consideration:

    1- Would be a smart solution the one which considers the creation of two different walls (EXTERIOR CORK FINISHING | STRUCTURAL X-LAM) with the first one reaching the final height over the gutter?

    2. With regards to the roof: I was wondering if a double roof would solve the different alignment between |structural beam+wooden panel| and the |insulation+cover finishing| layers. The first one starting from the wooden panel quota and the second one from the top of the wooden panel.

    3. Lastly: how to model the gutter? Maybe is a better idea to avoid its modelling and let an empty space on top of the structural wall?


    Thank you for your time in reading!

    The simplest way to model it is to use just use a single wall and a single roof structure. You can handle the minutia of how everything connects and layers in a detail view, you do not need to do this when modeled. You can accomplish this by using cut profile command to in that view only cut the structure short and add detail components to model the rest.

    As far as making the void for the gutter. Model it as an in place component that is a void and cut the roof with the void, you can then model in the gutter if you want to.

    Does this make sense.

      Hi Denis.

      Thank you for your kind reply and sorry for the delay.

      I agree with you for the detail issue: a better solution would be to put a detailed section view.

      With regards to the void for the gutter: I was trying to create it with a model-in place (roof type) and a consequent void extrusion as already done for some walls in the past. Nevertheless I just realised that even if I select the right work plane, after creating the void, this is not able to cut the element (as reported in the attached image).

      Where am I doing wrong? I tried also with the cut geometry tool but then there's no model to select to make the cut.

        After you model the void you have to use the cut command, just above the join command on the Modify tab to cut the roof with the void. Unfortunately you cannot just model a void and expect it to cut what you want. You have to tell it to cut this with this.

        Hope this helps

          Hi fconcas, if you are trying to cut your Roof as shown in my thumbnail (See Image) :laugh:,


          You can do it by using a Roof (in my case I used a by extrusion Roof) and then you go to Architecture - Opening - Vertical opening,


          If you're trying to use an In place Roof Component that will be an Inconvenient

          you must hit your Roof and the you need to add the opening; maybe a reference plane will be required, then you'll be able to cut your roof and then you should put a Gutter by hitting the gutter tool that if all goes weel will follow your opening , Hope this helps, regards

            This is also a viable solution. I do not think he wants the void to go all the way through the roof though. I think he only wants enough of a void for the gutter

              Hi dtp81390, Just a quick example to demonstrate how the tool works, then if he wants or not that is another question, :coffee: and again the solution will be as I shown in this thumbnail but this time is using the Cage tool I don't remember the name in English version! regards

                Franco I totally get it I was never saying that he couldnt do it that way I just wanted him to be aware that this tool cuts entirely through the roof whereas the void can cut partially through the roof. He just needs to pick what works best for his situation

                  Firstly, thank you everyone for the suggestions (or maybe "inspirations" would be a better word )

                  My aim was to obtain an hidden internal gutter as reported in the section view in my really first post.

                  https://www.revitforum.org/attachmen...oof-gronda.jpg

                  As suggested by dtp81390 this operation would have been too strenuous for the final purpose of a Revit Model and a detailed view could have been created to report all the information about the layers and their connection.

                  Therefore I tried to simply recreate the void of the internal hidden gutter. I realised that the cut geometry tool wasn't working because I used the "void" tool instead of the "sweep void" tool that let you select a 3D edge (this post was really helpful)

                  By using the sweep void Revit allowed me to use the cut geometry tool selecting the roof firstly and the void then.

                  Nevertheless I am not really satisfied of the final result





                  I reckon I got too many layers in the real situation and manage all of them with a simple void is not that easy and maybe even useless.

                  The final aim would be to obtain a better material takeoff of the external walls. The void created actually doesn't help with it since the external walls. Indeed, I should remove the wall to roof attachment, use the Create panel (Create Parts) tools to explode the layers view and extend manually the shallowest layer.

                  This is the result (visible just with the check on show parts):




                  Any suggestion? I wonder that a more simple solution would be avoid the gutter and manually take it into account later in the material takeoff.

                  But maybe there's a better solution.
