I currently started working in an architecture firm and am tasked with updating their revit families for casework. They are all super unorganized and not parametric at all. Does anybody know any good tutorials for advanced parameters or formulas for this particular job?? I’m familiar with the basics and can create simple parameters. So I’m looking to get a little bit more in depth.

Abstract: We present a deep learning algorithm for the numerical solution of parametric families of high-dimensional linear Kolmogorov partial differential equations (PDEs). Our method is based on reformulating the numerical approximation of a whole family of Kolmogorov PDEs as a single statistical learning problem using the Feynman-Kac formula. Successful numerical experiments are presented, which empirically confirm the functionality and efficiency of our proposed algorithm in the case of heat equations and Black-Scholes option pricing models parametrized by affine-linear coefficient functions. We show that a single deep neural network trained on simulated data is capable of learning the solution functions of an entire family of PDEs on a full space-time region. Most notably, our numerical observations and theoretical results also demonstrate that the proposed method does not suffer from the curse of dimensionality, distinguishing it from almost all standard numerical methods for PDEs.
The included families in revit are quite sparse by design. Most of the work I do doesn't benefit much from full custom families as I mostly work with many different smaller residential renovation/addition projects at a time, and I'm a one man revit team.
Having a robust, well made and consistent generic family pack would be awesome and time saving for me. Spending time hunting down a generic parametric sectional or 3-panel multi-slide window on Revit-City leaves a lot to be desired. Even manufacturer models don't cut it most of the time (over detailed or designed to be in a render and nothing more). Other than the time sink involved in finding an appropriate family, nobody tends to make these families plan/elevation ready either i.e. doors not showing swings on plans, or appearing as open on elevations, etc so I often have to spend time modifying them to work.
I'm at the point where I need to do either two things: spend a bunch of time modeling out parametric generic families for furniture/doors/windows/etc or find a pack where someone already did all that. I'd love to just do the latter to save me a lot of time. It looked like the xrev team had one made on their website but as far as I can tell there's no way to purchase it and they don't "advertise" it at all? I'm open to other suggestions too!
How can I show that? Thanks.

Hi again everyone.
Im creating this family:
I want to make it parametric, I mean: when large is changed, the louver large changes its size too, including the frame.
I dont know if the constraints are wrong or the extrusions I created for the frame:
Can you help me?
Hello dear Revit community. I have a question on building a new Family. I am currently stuck on a the problem on how to bind an element that is grouped by an array. ( it has to be there is no way around it. ) And the problem is if I bind it on both ends it says its invalid and has to lose those ends. The element itself should not only move but it should stretch itself when adjusting the width.
I would like to post a picture but its not allowed here >.>
Very new to revit, I'm currently trying to make a cylindrical parametric family, but have only been able to tie the length to the parameter. I've created the reference planes and dimensions but how do I attach the diameter of the cylinder to my "width" or "height" parameters?
Hey everyone, I'm currently in Puerto Rico holding on for dear life. I have been reading about survival analysis because it's the perfect tool for a problem in tackling currently.
Initially, I thought a Cox proportional hazards model would be great because it seems to be the favorite model out there. However, I intend to use the results to project currently censored individuals to the future and that is not possible with Cox (since baseline is never really specified).
Because I am interested in inputing covariates getting output "probability of failure at time t", it seems a parametric survival model will be optimal. Most of the literature I have found indicates that a simple exponential distribution works remarkably well for tha vast majority of uses, so I'm inclined to try that. However, for my precise problem, there will be competing risks and I believe that they work fundamentally different across time.
A bit of background on the issue. I am trying to estimate probability of departure from a company for each individual in it given a vector of covariates which include: division, wage, age, position...The competing risks are that a person can leave by will, be booted or retire. I expect retirement hazard specifically to be very low at the beginning of tenure and to spike up at the end of the span.
What parametric family works for what type of hazard ? Is there a systematic way of determining the specification based off the data, or is it just intuition ?
Im sorry if this is stupid, I started reading about survival analysis yesterday. Also, sorry for the spelling mistakes, I have no electricity and typed this on my phone.
Thanks a lot for your help. Hope everyone affected by Irma stays safe.
Hi /r/revit. I have a question about parametric families.
I've been trying to understand how to use parameters in building modeling, and I feel like I've hit a wall. I downloaded the Gigabidea plugin (from what I've seen, it multiplies a family object with the proper parameters) after watching this video. I'm trying to design a high-rise for a class and it's essentially the walkway in that video but rotated 90 degrees.
The product I've made after watching that video rotates and buckles in and out, but I want to make it also shrink in area as it rises. Basically I want to add a type of height parameter that will make each incremental panel decrease in overall square footage while maintaining the flow of the curves. I have a min and a max square footage for the base and the cap. How would I do this?
I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.
Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
Do your worst!
I'm surprised it hasn't decade.
For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.
I said "hey look, an escaPEA"
No one near me but it didn't half make me laugh for a good hour or so!
Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂
It really does, I swear!
Because she wanted to see the task manager.
Heard they've been doing some shady business.
Today I have been imagining what Rust could be like if it had associated type families, like Haskell, and parametrized modules, like Standard ML. In particular, this would allow us to implement STL-like iterators and algorithms, in a type safe and modular way:
https://gist.github.com/eduardoleon/10120521
In Haskell, associated type families allow type classes to have type members. In my snippet, I extended this with the possibility to add methods to these type members - traits can have impl members for their own type members.
I provide four examples of the expressive power this affords us:
-
"Functor instances" (map) for Source (input iterator) and Peekable.
-
"Contravariant instance" (contramap) for Sink (output iterator).
-
A safe port of C++'s std::transform from the <algorithm> header.
-
A zip iterator that, when used on iterators of different lenghts, returns as leftovers the unused elements of the longest iterator.
They’re on standbi
Pilot on me!!
Nothing, he was gladiator.
Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.
This sub is mostly just NSFW puns now.
If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.
Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.
Or would that be too forward thinking?
