Hey vulcan architect it’s guys here and in today’s video i’m going to be talking about one of the most underrated tools in revit so joint geometry is one of my favorite tools in rabbit i know i sound like a kid i have a favorite rabbit tool
But that’s the truth and i think it’s a little bit underrated people don’t know how to use it it’s not common knowledge when it comes to people that use revit it’s not common knowledge how exactly this tool works and how it can improve your workflow and what are some of the
Important things that you should know before you use the tool because in the end the project documentation that you produce it heavily relies on the proper use of this tool so it’s really crucial to know how exactly it works and that’s why i decided to make this video
Where i’m just going to go step by step explaining how the tool works how it operates and how it changes the data that you create in revit when you use this tool so that’s what this video is going to be all about now if you want to learn more about
Revit actually have a website with over 100 hours of courses so it’s going to be the first link just below the video it’s called balkan arctic.com and there i take the extra time to go slowly step by step and explore all of the rabbits uh beginner intermediate as well as advanced level
Topics so if you’re interested please check it out also make sure to check out my patreon that’s going to be the second link in the description and that’s where i upload all of my revit project files so make sure to check that out as well and also make sure to like this video
Helps me out a lot and helps promote the video to other people that might want to see that and as i said this is an important topic and finally make sure to subscribe i make useful private tutorials each week i make three tutorials so make sense not to miss them okay sorry
For all of this now without any further ado let’s get straight into rabbit and here we are in revit so this is just going to be the first in a demonstration of the most basic and rudimentary form of joint geometry how you can use it to kind of fix certain situations in revit
So here you can see that i have a wall so this is just a simple wall segment here we have a floor and then here we have a little beam segment now just if you’re wondering how i managed to make this look like a section in 3d it’s simply by using a
Section box which is currently hidden if i were to go here to reveal hidden elements you can see that this is a very very long section box that’s kind of cutting this little detail out anyways so here we have that segment and here i have an actual section where you can see that
So a wall a beam and then also a floor here now the main material here that you know this is this gray material which is concrete so usually if you have a wall that looks like this and a floor and a beam uh and everything is
Made out of concrete so this part of the wall is concrete this concrete in this concrete that should all kind of come together uh in in just one kind of model it so let’s see how can we use the join geometry tool to join this together
So join geometry is located here on the modify tab and it’s on the geometry panel and here we have the join geometry that is not to be confused with the cut geometry anyways you just click on the join geometry tool so just click here on the main tool
Or you can expand the drop menu to see the the rest of the options but let’s just click on the main tool and then you can well join some geometry so first you click on one of the elements let’s say here the wall and then i’m just going to click on the
Beam and it’s just going to join those two together so these two are now together but still the floor is kind of separate so now we can select that beam and the floor and now that is joined together but still here we have a small issue
Now the reason for this issue is because the floor and the wall are not joined together yet so let me just join these two together and as you can see now this is one kind of completed segment of wall beam and floor now i’m just going to hit the escape key
A couple of times and then go back a few steps before this was all joined together so something that’s really important that they would like to show you is what this join geometry tool actually does to the model elements so let’s now transfer to the 3d view and now let’s select this
Floor segment that we have here so if i select this floor segment go to our properties if i scroll down here under dimensions you will see that revit actually reports the perimeter the area the volume and so on now in this case the volume is what i’m interested in
And i’m interesting to see interested in seeing the change what happens when i join all of this geometry together so let’s select this floor for example and i’m just going to open up the snipping tool here and i’m just going to take a little snip and just take this information here i can
Even highlight that simply like this so this is the volume so this is what i’m interested in and i’m just going to drag this over to my second screen anyways now let’s go to join geometry so again on the modify tab draw on the geometry panel join geometry and then let’s select
The beam and the wall and then also the beam and the floor and then the wall and the floor and now it’s all joined together hit the escape a couple of times now if i select this floor and come here so as you can see the volume
Has stayed the same so the volume did not change so even though we’ve joined these two together it’s going to keep this kind of going all the way to the inside so it’s kind of measuring this as kind of the main volume of this floor if i select the
Beam as you can see the beam only highlights on the bottom and then if i select the wall the wall highlights over here so looking from this the main part uh is the floor so the floor kind of goes all the way through and then kind of one at the whole
Join geometry but we do have an option where we can switch the join order so we can switch this from being in the main one to perhaps the beam being the main one or the wall being the main one in this case i’m guessing the beam
Should probably be the kind of the main structural element so what we can do in that case is simply go here to join geometry open up the drop menu and go go to switch join order this allows us to select two elements and then revit is going to switch the drawing order
So now if i select this as you can see only this part highlights it no longer highlights all the way to the inside and if we select the beam the whole beam highlights and if i select the wall the wall highlights only here but not where the beam is
Now if i go back here and select this floor now it’s going to report something different so currently the volume is 1 meter and 4.4 and if i open up my snipping tool as you can see it’s kind of different so here it’s 1.875 and here it’s
1.475 so the volume is going to change but only to those elements that are affected or subtracted using joint geometry so this is something to take into consideration so for a situation such as this it’s really important to define at least to yourself what is going to be
The main element here what’s the kind of the main element is it the floor is it the beam or is it the wall and then you use that in order to play around with the join order so you can go here to switch join order
And then you can switch it from the beam and the wall and now as you can see we have a gap now the reason for the gap is because we’ve told revit that our beam or our beam is more important than the floor and then we told it that
The wall is more important than the beam so in the end we kind of found ourselves in a situation where there is a gap in the middle if i go here and can we see that we are the gap so we can go again to switch join order
And then we can switch the join order between these two and now we have a different situation so here the the wall is the main element then we have the beam that’s kind of on that and then we have the then we have our floor so we can just go and play
Around with this all day long playing around with different join orders and then see how that is going to appear uh when we select the elements and selecting elements is usually the best way to determine uh what is the correct join order and which element is stays here so in this case only
The beams stay the same the floor is smaller and obviously the the wall is smaller by this section of the wall here so this is really important not only because it’s going to define how your model looks either in 3d sections or flat sections but also because it’s going to change
How your model reports the amounts of materials included so here we we have obviously less concrete in this floor than than we did before we’ve joined it to the wall so it’s really important to join your elements because it’s going to make it look nicer but also it’s going to give
You a more accurate quantity of materials which is going to give you a more accurate cost calculation which is going to make your client very happy because you’re giving them an accurate estimate and also you’re not counting double the materials in areas such as these here where we have
Three elements the floor the wall and the beam overlapping in one space anyways uh one more thing that’s really important when it comes to join geometry is what to do in a situation such as this one here where we have multiple elements together so here as you can see we have these
This beam system of multiple beams and then it’s basically overlapping with this floor so let’s say that we want to join all of this together well we can go to our modify tab we can go to our geometry panel go to join geometry and then we have this button that says multiple join
So if i just track that it’s going to allow me to select first the element that’s going to the main element so here we have the floor and then all of the beams are joining to that floor so we first select the main one and then we can select all of the
Individual beams and just add those to that floor as you can see if you had to select the floor and the beam for each one it would definitely take a long time and like this it’s really a quick and easy process and of course keep that and keep in mind
That at any point you can go back to your modify tab back to join geometry and you can just go to unjoin geometry this is simply going to allow you to just unjoin those elements here because this was a multiple drawing it just unjoined them all and if i were
To go here to this section go to unjoin geometry as you can see i can just remove things from that join so as soon as you select the element it’s going to unjoin it from all the adjacent geometry so there you go that’s the join geometry tool
It’s one of the most underrated tools in revit at least in my opinion because it’s it’s my favorite tool to be honest but anyways it is really useful it is uh it is going to give you a more accurate estimate or accurate quantity and then also it’s going to make
Everything look nicer and well correct to be honest so there you go that’s the join geometry tool make sure to subscribe for more videos i upload videos each week i have three videos coming out and also make sure to like and share this video it does help me out a lot
