Make a Groin Vault Roof in Revit

[@petermlouis]

wow this is soo much easier than the way i tried to do it. thank you

[@PaulAubin]

+Peter Louis Glad you liked it. Thanks!

[@hassandan8841]

Thanks a lot for this nice video. I tried importing this file to robot analysis, but nothing is showing on the interface of robot program. what is the reason?

[@nadaelzoghby8541]

That is very useful and quite easy to handle. Thanks a lot. :)

[@PaulAubin]

My pleasure. Thank you.

Hi ... I came accross this post following a link on Autodesk'd forum ... Since I am pretty much fond of your work I just thought I would leave a note :)PS: The issue with Revit not being able to join the two roofs is not the top being at same height ...It is the bottom (ie: the Rafter Cut) ... - it cannot be plumb (which is the case here) => cannot be acheived with a perfect half circle Arch that has it's center at the midpoint between & aligned with the 2 bottom/start ingpoint. Should the center be 1mm higher (not lower) than the lowest point of the Arch Revit will not have an issue joining the two roofs... the transfered load/force tangent to the arc at the bottom has to point towards the inside (cannot point out or vertical)

+MINIJODA RDAOU Thanks for the comments. I'll try out what you suggest. There was also a response that suggested using roof voids. So as always there are lots of ways to solve the problem. Thanks again.

[@rdaou]

+Paul Aubin It might be also worth noting that extruding the main roof using 2x quarters would help Revit figure to which side to join... It's here on this link -> knowledge.autodesk.com/community/screencast/af0d76a9-c422-4935-a315-e15479e33004

Hello Paul. Great technique thanks for sharing. one question will it calculate material volume, surface area?

[@PaulAubin]

Glad you like it. Try doing a material takeoff. That should give you what you need.

[@emilielawson585]

I have created vaults using the Model In Place tool under Components and categorizing them as ceilings. How would I join these elements as you have done in your video?

[@PaulAubin]

You have to do this inside the in-place model.

[@abdohkair7039]

thank you a lot and I hope that you will find the straight right path

[@andreamantecong]

Great video!!! Thank you very much!

[@PaulAubin]

+Andrea Mantecon Glad you like it. Thank you!

[@paigebrunault4095]

Would you use the same technique for roofs that are not perpendicular? Or with more than two roofs?

[@PaulAubin]

Sure. You can use this technique on any roofs.

[@paigebrunault8054]

Thanks Paul - I managed the simple two roofs at 90 degrees from each other but I was wanting to model three at 60 degrees from each other ... totally not working ... the original two seem okay but the third roof isn't cut with the voids, even when I choose it. Any help would be greatly appreciated.

OMG thanks, you're a hero :)

sir how to apply embedded curtaint wall in sloped roof

[@PaulAubin]

Make a roof first with a hole in it. You can make the hole in the sketch or using an opening element. Then add a second roof. You can copy and paste the original and edit its sketch to make it match just the shape of the hole. Then on Properties, make the copied roof sloped glazing.

well played, well played

[@petermlouis]

hey paul ive successfully created a "groin vault roof" according to the steps on your tutorial but i realized it was the wrong way to go. what i am trying to achieve is a very similar structure to that of the hagia sophia dome. where there are four arcs at a cross shape then a dome on top. How can i achieve that dome structure on top of the four arcs? any simple way to do this?

[@PaulAubin]

+Peter Louis You'll need to do an in-place family for the dome. You can use a revolve form in the in-place.

[@petermlouis]

hello Paul, i ended up revolving it from a vertical face as a half elipse and it looks great but now im stuck with the dome looking rather odd on top of the 4 other domes (the groin vault), i need the dome and the groin vault to become connected smoothly and im clueless as to how to achieve that

[@PaulAubin]

Peter Louis Try taking a look at this: grevity.blogspot.com/2015/09/john-soane-canopy-domes.html There are plenty of terrific posts like this all over the Grevity blog. Definitely worth following!

[@petermlouis]

hey paul i had a quick skim through it and i actually saw the shape im trying to form, not sure if it explains how to achieve it but thats definitely a start as i could not previously find it anywhere, thank you very much.

[@PaulAubin]

I think he provides files you can download. If not, just ask him. He will be happy to provide I'm sure.
