- (Quarantine Day 175)
Today we are going to quickly model some roof structure.
As I said in the comments, this exercise is only to show you some basic method we can use to place the structural framing. The truss itself is probably not right because there are many facts that will affect the design of the truss, like the size of the roof, the load, the location of the house etc.
Maybe we need some help from the builder or truss manufacturer. :)
Thank you, you have the best content.
awesome work and skills !!
Would love to see more Revit learning videos how to build wood framing house.
Although most of the houses here(Australia) are timber framed, most of the time we do not model any timber members except those major columns or beams, unless the client is paying for that?
This is helpful and instruct full ❤
Thanks for this video
Hello, thank you for your great video! Is there a way to join the beams so they have a flush connection? For example, making the rafters meet the ridge flush at that angle.
Yes, you can use the Cope tool.
@@BINHE615 It seems that when I use the Cope tool, there is a gap between the elements. Is there a way to eliminate this gap so the two elements are touching? Thank you again for the video and thank you for your response.
@@Glorbs444 Select one of the beam and find the Notching Distance
thank you...can you make details of wood with dimensions ready to cut?.... for instance , if I want to precut all the framing instead of cutting them at the job site....
I want to make my own business but WI ant to pre-fab as much as I can before installing it
I think you can create a structural framing schedule and list the length of all the timber frames. But it’s probably not very accurate. Maybe you should check and see if there is a timber framing addin for Revit?
hi, Bin He thanks for this video it is very helpful, in case I want to change the slope of the roof is there a way to align the hip rafters so they can follow the slope? I tried changing the roof slope, I'm not sure which slope I want to set for the final design, and some beams, mainly the hip rafter beams and some individual beams from the beam system stay on the same position while the roof changed slope. I fixed the beam system by doing a reset but I could not change the individual beams on the hip rafter.
To be honest I don’t know how to make the rafter you follow the roof (height), I would just use the spot elevation to find out the height and manually adjust the 2 heights for the rafter.
@@BINHE615 I was thinking if it is possible to create truss just with the top beam and align it to the roof. Thanks I will use the spot elevation. Trusses are kind of confusing.
@@CrlsE094 Yes, I think it's possible to use the truss. But I don't think you can simply align the top beam to the roof. What I can think of is to create a truss with an angular parameter for the pitch, so you can easily adjust the angle when you need to change the pitch. What do you think?
@@BINHE615 I believe that trusses have the Attach top base option like in walls if I’m not mistaking. What I’m not sure is to what side is going to be attached because the hip rafter is not plane, it is a line. I think I will watch your truss videos, I find trusses very confusing hehe . I was thinking of a truss just with a top and bottom chord for structure support and the option to extend the top cord, in order to have a high ceiling or vaulted ceiling. But as you said, controlling the angle with a global parameter will be a more simple solution.
Thanks for this. Curious why you did not attach the roof to Level 1?
It's up to you I guess. I refer placing the roof on floor plan so I can roughly tell the height by selecting it, actually, I like to model everything on the floor plan to have minimal amount of levels. :)
If you place the roof on the Level 1, you can adjust the roof height by adjusting the height of Level 1.
You will figure this out and find your preference soon.
Amazing👍 just can you please show us with the same example how to make the trusses especially in the change of direction of the cover
TBH I don't know how these trusses will be designed. You probably need to find some builder, or people from truss manufacturer and ask them. Once you have the design of the truss and you will be able to model this using the method in this video. But most of the time the truss manufacturer will take care of this I believe.
If you are referring to this image ibb.co/PtQQvmj
I don't think there is much difference.
Hi Bin nice video but very fast. I was following your video but whenever i put the top plate in place it always position on the bottom. What should i do for it to go to top?Thank you
You probably skip the part where I adjusted the height of the truss. Select the truss and in the properties you would see a couple of height parameters.
hi.My teacher says that he gives an error with the pick line and he cannot create it. what could be the problem (talking about mahya lovers)
Yes, sometimes this does happen. What you can do is uncheck the 3D Snapping, create the beam first, then adjust the Start Level Offset and End Level Offset manually. I'm not sure why this happens, maybe they just don't like each other.
How do u make facia without set work plane just pick line with just 3d snapping ?i have just tried it many time it said cant create then i set work plane so i can make facia?
You can use the fascia tool under the Architecture - Roof tab.
@@BINHE615 sorry i maen in minute 3.42 how do u select it without select work plane
Yes, you have the option to 3D snapping while place structure beam, but sometimes it does not work. Instead you can set work plane first and place it without 3D snapping check. This will create a member in that selected work plane.
And what about if there were a former window in between ??
Tbh, I don't know. Generally, I would not model any of these roof structure. The truss manufacture or builder will take care of them. If you do need to model them yourself, I recommend you consult these people so you can do it properly.
Yes How to make the trusses sir in this shape of roof 🤔
The intension of this exercise is to show you some basic method of modelling, eg. beams, beams systems etc. I don't really know how this truss will be designed tbh. Maybe we need to ask some builder or truss manufacturer people to help us. :)
why i cant pick a plane like u do its not showing triangle plan 5:52
Do you have the Select Elements by Face on?
The frame doesnt connect each others...
You can try the setting under the Pattern of the beam system.
why do we duplicate beams? I dont get it someone please
Can I help?
@@BINHE615 yea , we do you duplicate beams when you go to edit
I’m afraid I still don’t get you. Can you show me the time in this video where you have this question?
@@BINHE615 ok, in minute 2:14 why do you duplicate the beam, or used this duplicate function, can't I just go to load family every time I need a beam?
Yes, you can. I prefer using some standard size, eg. 45x90 instead of 38x89, so have to create those new type. Sometimes I will just duplicate types because it's faster to do so than loading it from the library. :)
help me
Your mouse clicks are louder than your voice mate.
😆 . Sorry about that.
jesus that mouse click is annoying!
Sorry about that. :)
