Everyday Revit (Day 253) - Adaptive Chain Family

hey guys bing here um today i'm going to show you how to model this um adaptive chain family so you will be able to just adjust the point so it will follow the point and you can make it longer and also you can change the size of the under each one so hopefully make it smaller make it bigger okay so let's start so first create a generic model adaptive and um just place one point another point okay so and then make adaptive spline reference line so then another point put another two points draw on face and one two so i'm going to show you the um what i'm going to do to do okay so so here this will be one segment of that chain so it will be uh something like this so this will be the internal face of this chain right and um so the uh this will be the the path of the sweep and then i'm just going to uh so from this point do a half circles from this point half circle okay so half circle half circle and a straight line so that's it so let's do it so now we have these two points so uh we need more so points uh draw our claim set workland pick the horizontal workplane and place it on the point you should see this warning and ok and place on this point drag it down and place another point set and pick the horizontal wall plane again and then place it on this point and okay this time drag it up so let's repeat draw on workplane set or plan tab and place it the point drag it down and another one um and this time it goes up so now we need um create this parameter so from here to here so from this point to this point so it's actually a radius so see so it's a radius of chords are one yeah so let's create a radius r instance okay and okay same this one i'll just use this r and this one because it's a negative one so i'm going to create another one so let's call it r negative instance okay and okay so this one i'll link to the r negative go back to family types are negative equals negative r apply okay so um now the next next step let's go have a look at this one so because we want this internal thing so so uh actually let me just do the profile of the this radius the little circle here on this path so go i'll just do the finished parts first sorry so select these two points spline reference line so that these pop two points find reference line and also for this arc so i'll draw a uh so half circle using this point okay so reference so uh this one center and arc and draw a work plan step one plane pick the pick the vertical work pencil tab tab so this one and then click here here drag it down to here so that's it so you don't need to lock i don't think you need yeah so click on this little icon here and then this is the radius um radius so it's same as this offset the offset offset of this point so i can actually just link to this right so uh so repeat this this this descent and just center ends arc draw our plane set more plane tab tab pick this workplace and place it from here to here then radius again then link this to radio r so now i need to move this point okay so so um before i set this point the location of this point i'm going to do this this circle so we can get the these radius okay so i'll just place one point uh draw our face and anywhere on this weapons line and then do a reference circle draw our plan set or plan and pick this vertical work plan and then draw a circle on it and click on this icon and then create another radius alcohol r2 or little r okay instance okay so now i just roughly change it to make it smaller um so now if i have a look of this one so because this one is r and i if if i want this uh this sway the internal face to match this point so i need this one this one will be r minus this bit this bit is actually this radius the small r okay so go back to reddit so click on this point so here i change the measurement type to segment length and then here i'll create a new parameter so here i'm going to call it offset of instance okay and okay so now if i go to family type o f equals capital r minus lowercase r apply okay so now if i so if i create this sweep so you will see this way this will go right through this point okay so now i'll just same this one change change this to a segment length and for this one actually i need to change this to and and then i can link this to offset okay so now if i select this one the profile and the path one two three four create form so this will be the sweep okay so now we need to somehow um so because this is uh compared to the radius the this radius the little the log is radius a little bit too small right so let's go to family type so the small lowercase r let's try maybe r divided by two oh sorry yeah capital r divided by two so apply um this looks like too small when you have another one or maybe what we can do is divide by 2 um 0.2 yep that i think that's probably better even 2.4 maybe yeah i'll say 2.3 okay so now another thing is the the length so um what we can do is we set work plan pick this reference line and then d i pick this uh adaptive point and also this one make sure you pick this point okay so this will be the length of the um the um the the length between these two uh data points so we can create a reporting parameter i'll call it length l instance recording okay so now what we need to do is to um to give this capital r a formula so let me try r equal l divided by three apply um i think that's that's okay so yeah let's let me try divide by two that's probably too fat maybe uh 2.5 yeah that looks okay maybe 2.7 okay so i think three okay yeah okay i'll just use three so okay so now this is finished and also because we we want to rotate this sweep when we create that chain so what we can let me just try so select this point and i'll see if i can rotate it 90 degrees nope negative 90 yes let me try this one negative 90 so yeah so now i know that uh i can use negative naughty so i'll select these two points and then here i'm going to create a an angle parameter or call it a instance okay and okay so now this is finished so now what we need is we need to create another generic model adaptive and i'll just create just put so i'll i'll just put three pawns so you can place uh as many as you like so but uh i think space okay for me and then create the spline and reference line okay and select this as reference line click on divide path and here so instead of fixed number i'll change it to change it to change it to fixed distance so and also you can actually create um let me just uh create create a parameter so this will be the um i'll say um the the length of each segment okay so oops sorry what did i click create or call it a segment there and instance okay and okay so now i'll actually change this to maybe 200 okay oh that's a little bit too much i'll change it forward oh i'll just use 200 and i'll just move the point to close to each other so the will be less less less segments so now go back to this one and load this into here so don't worry about this the size because when you place it so make sure so you start from one direction okay so you don't don't you don't don't do it like uh this way and that way so so so to do it from the maybe from this one to here and then from this point to here so now select the second one so we know that we can oh that's nine minute negative large that's okay i'll change it to zero so now so we've got two of them so and then select select both both of them and then click on this repeat now we have this chain and if i move this so you can see it instantly um adjust the each segment right and also um if because we have that uh parameter there so this one for number if i change to 100 it will become a smaller chain yeah and if i change it to 300 big one 500 okay so now let's have a look um i'll close this one and i'll create a project so we can have a test so i'll just create two wall here and then i'll load this into the project so go to 3d view i'll create a chain to change this to wall okay so one uh maybe let me go down to the floor and then yeah so okay and then we also have this one segment let's make it smaller smaller yeah so that's it yeah i hope you like it and if you have any question please let me know um i'll see you next time thank you bye
