Rhino Grasshopper Architecture (Isenberg Business Hub)

in this Rhonda grasshopper architecture tutorial I want to model the Eisenberg business hub in grasshopper in right aligned grasshopper so you can understand how we can model these sections as you can see in this building and it's rotating to reach this section so I'm going to show you how to make this in rhino and grasper before we start this tutorial I'm going to show you some of the images of this building and also video about how this building has been built so be sure to watch the video till the end because then we will start modeling this in Rhino and grasshopper [Music] [Music] [Music] [Music] [Music] [Music] before we start this tutorial if you're new to our channel welcome consider subscribing because we have weekly tutorials and I will also put up a video up here which is about what is right now and grasshopper and why you should learn it and also a beginners tutorial so if you're new to our channel you can watch this playlist and also we have an advanced lessons about grasshopper weekly we are going to switch on two or three weekly tutorials for our course so be sure to watch our course lessons also up here I will put the playlist you can see what we are adding to the course and enroll in our power course lessons okay let's get started from scratch okay so first what we have to do is to produce the base surface of the structure and as you can see I have modeled this in Rhino I would explain how we can produce and model this surface so the base of this is if you look at this we have a complete arc on this here which is let me just draw this 270 degrees then we go down we have a 180 degrees arc and then we would have to extend that in a line right so we have two sections here then we will give the rails for the up and down and these sections for the surface and we're good to go so remember we have to make those arcs the sections and then finish the model so now what we want to do is to go to the arc I'm going to give it a zero so the center is zero I'm going to use the shift key to make an orzo and bring that like 270 degrees and that's going to go a little bit up remember before that I'm going to again draw an arc and use to snap to this and make this 180 degrees so let's just bring this up this is based on your project and the heart of the project you want and now what we want to do is to extend this arc so I'm going to type extend you can use is the extend tool here let's just type this stand we don't need a boundary so we just say okay the curve to extend is going to be a line the type is line and we just select this one we extend it to the end and reach the step okay though step is has to be on and we'll finish that okay the next is the section so I'm going to draw a section here a section at the end of the arc we have to find that and that's the knot Oh a snap on and I'm going to click here use the control key to bring it up and snap into my second arc and again this one so now what we want to do is to produce a surface from this and the command which uses that rails is sweep to the sweep to command uses two rails this will be the first rail this will be the second rail and bees are going to be the sections right so what we want to do is to use the sweep to the first rail second rail sections and okay and you can see that it said it's going to give you a neat and a uniform web surface we can also rebuild that if we want to make it more uniform so remember to rebuild it if you want to and you can see that these eyes occurs are completely correct because they are going up and they are not tilted so what we want to do is to work with this in grasshopper and get started so I'm going to go to the palms menu go to the geometry and select a surface to set it to this surface and let's just turn this off and delete these lines we will need the line at the bottom so I'm going to just delete these lines okay the next section the next part of this tutorial is to how to find those curves on this one and as you can see it's going to be perpendicular and then when we go forward at this part it's going to be a little bit tilted right so how can we do that I'm going to go to the curve section set this curve to the base curve at the bottom and now they use a - in the curved section called the preventable of frames okay if you don't know about this we also have another tutorial about pipe in the groove frame so I will put it up here check it out for now we can just set this to the curve and increase the number of the counts of the perpendicular frames this will give you perpendicular frames on the base of this surface okay now we have to bring sections on this surface with these frames I'm going to go to the intersection and select this one mathematical be red plane that means we want to intersect the be red with a plane so we can give this to the B rep and these to the plane okay after we give that there's a problem as you can see we have sections here the reason here is that some of these planes because plane is in the mathematical section that means it's infinite what happens is that this plane is going to go extend it and have an intersection also with this part okay so if we just go into the curve section you can see that we have two sometimes two different sections sometimes one how can we just extract the one we want the way in the technique you can use is really simple first we're going to connect a point to these planes that means we're going to interest in extract the center of these planes then what I want to do is to go to the curve section and select a point on curve so I'm going to extract a point on these curves okay and you can see that we can see these sections when I go up and down what I want to do is to extract a point and find the nearest one to the center of the plane you can see that this one is exactly what we are doing what we want to extract right so we can just put that at the start now what I want to do is to find the distance between these right so I'm going to use a CP point CP point to do that you can also search for CP and select the closest point okay when we say CP point we are searching the distance between these points and the center of this right and remember you have to also graph this so each of those sections you can see we have 35 groups go to 35 centers okay if you don't know why I'm graphing this because perhaps grasshopper hat is a little bit advanced and it's a programming language we have to make them into the same data we are analyzing so if you don't know about graph you can watch a tutorial up here I will put it and I have explained about graphed flatten on those things okay now what we have to do is to let me connect a panel to the distance here okay you can see when we have two different sections some of them are near the center point or the plane point and some of them are far okay we need to extract that one which is near it so first of all I'm going to use this technique of sort and sort these keys so it's going to sort it you can see that it has let me just show you here it has changed the location of 35 and zero so it going to sort from minimum to maximum as we are sorting these values we have to also sort those curves so I'm going to you can always add different curves to this so I'm going to say by sorting these distances also sort these curves okay so this will be the first curve and this will be the second curve now what we want to do is to extract all the first inputs so I'm going to go to the sets and pick up the list item and select the first one okay excuse me from the curves we want to select the first one and that so remember the technique when you want to use a plane because it's infinite is going to intersect with different sections of the curve is this technique you have to first of all pick up a point then extract the point of the plane use the CP point to find the distance sorted and then pick up the curves or the first distance right and this will give you the girls that's it so the problem here is that it's a curved section we want a straight line okay if I want to show you here we need a straight line so that's also easy we want to go to the curved section and pick up this end points and we can extract the start in the end and make it or remodel this with a line so that's really going to help us to make this happen okay I'm going to turn everything off and now you can see that you have made those lines from that surface we can also increase or decrease the numbers of this let's just turn this off and have the base section okay if I bake these lines and select all of them and put on the other wise direction you can see that every or all of them are going up but the last one is going down okay so the problem here is that the last one is in a different direction from all of the other curves again we have to fix this because it's going to have a problem with the sweep we're going to use or about the extrusion technique is first of all we have to flatten this because these lines are in groups so we have 49 groups again when we flatten we have 49 lines in one group so check out the flatten and graph tutorials so I'm going to flatten this we have this 49 lines then just type flip we have different flip tools but we want to use the slip curve so I'm going to use this flip curve and give it to this you need to say a guide line okay a guide curve we want to pick the first line so I'm going to go to the sets and pick up the list item the first line is the guide and says flip all of those curves based on the first line so now if I bake this you can see that all of them are in one direction so this is another technique you have to use if you want to have them all in one direction and remember grasshopper is a little bit more complicated than Rhino rhino will maybe sort of find the direction itself but grasshopper you have to have the right direction okay that's it now we have to finish this tutorial by giving them thickness so I'm going to go and use the offset tool give the cursor the offset and you can see some of them are going to go inside some of them are going to go outside we have to fix that by giving the plane of this the curves what is the plane of these curves we have them here right we have to offset them in these planes so we can just give that to the plane turned that off and now you can see that they are all going to go in one direction because we want to go outside we can just go expression and say minus X and offset that okay now we have to just join them together so I'm going to pick up a curve just to explain why we have to graft or flatten this okay when you upset a curve you can see it's going to put it in groups so first of all this base curve is not in groups and this one is in groups if we want to lock these together and let me just put them into one group so I can explain that we have to have groups of two so remember you have to graph this so both of these lines are in one set of groups and you can see when we add them up we have a problem here okay the next thing about offset is that when it has it puts it in one groups it gives us zero to that okay so when you working with offset remember this technique we have talked about in our course lessons many time when you're offsetting remember first check the graft then second check the simplify thing right click and simplify we have talked this about in also you can watch the flattened rafter to look again that will put up all the zeros down and then we will have them all in groups of two that means we want to lock them two by two and that's the technique we can use so I'm going to lock these together and we can just increase the distance and you can see that this is exactly what the structure looks like and now we have to just give that an extrusion and a thickness if we want to how can we do that we can extrude that in the normal direction so if we go to the planes the technique you can use is to give power arms and a vector to the plane so another technique if you just give a vector to a frame it's going to give the z direction of that and we can use that for our project so now we have to extrude it's just about flattened and graphed again these are not in groups these are in groups so I'm going to graph that and then multiply that with the math section multiply that with a number so I'm going to give them a number then give that to the extrusion so you can also extrude that in the normal direction that's it and you can see that it's going to give you the results okay again we can control the offset we can decrease the numbers so you can see how great it is for grasshopper to help you with your projects if you want to produce the structure because if you want to make that in Rhyno you can't control the thickness you can't control the numbers and you have to change it all the time but now if you just give the base surface and the line of the curve excuse me if you give the base surface and the base curve you will always have these structural sections on the model so you can just bake that and produce the results so that was the tutorial of how you can make that let's just close this one how we can make those sections and then you can just work with that surface to build your project and go forward okay that was a tutorial of how you can make this a rival grasshopper thanks for watching remember to like this video so it can reach other people because if you like our video YouTube will show you more of our videos and also
