hello /3/ I never post here, um do any of you's use rhino/grashopper? I want to get a plugin that can generate a bunch of mesh's based on one original mesh but the ones generated are modified by some parameter, like a plugin the would take a square mesh, for example, then the plugin gets the user to specify how to square would be changed, ie remove/add some volume from the square, and then the plugin would generate a bunch of new squares the have the removed/added volumes in different places, basically I want to do what the gif ive posted is doing but instead of instead of it happening to the same model I want to have an array of all the versions generated, hopefully this made some sense
Tell us what you want to really achieve.
These randomized generator always sound good in theory, but will break in many tasks, so it depends on the usecase.
basically I study architecture and to justify our designs we have to come up with a bunch of concept models that give us the general form of a building that we are designing, its kinda tedious to do it all one by one so I figured there'd be some plugin to automate it, I don't have a specific usecase now because I'm on break so im just trying to make my design process less tedious, if you know any plugins like this or the names of what these types of plugins are called that would be appreciated
Just do your homework by hand.
If you add up installation, learning and failed attempts, you'll spend much more time trying to get a half-decent procedural thingy going than just creating ten or twenty variations by hand.
I doubt your school requires you to present 1000 variations, which might warrant a procedural approach.
im on break, I just find this stuff fun, can't you just tell me if you know?
Many 3D applications allow you to script some stuff, including mesh generation and usage of boolean operations, which would be the imho best approach.

You could write a function, which creates a bunch of cubes with different scales, then creates a bunch of cubes which have varying scales and distances from the first cubes and then you apply an add/subtract modifiers every time.

If you want to go an extra mile search for plugins/projects which already creates procedurally generated stuff, reverse engineer it and try to create your own plugin from there.

It's not too easy and rather specific though.
Ask a dedicated community for help:
ok yeh I was thinking of learning how to write scripts for grasshopper/rhino, I always have stuff that I want to do that I can't find, I guess ill have to bite the bullet, at least I know some basic programming already, thanks for your help, also you're kinda right my uni doesn't require us to generate thousands of models but the students that just do whats required usually get C's, it probably is more work than its worth to learn all this stuff but like I said I enjoy it and it doesn't hurt to learn more stuff

If you have an intermediate understanding of grasshopper its nothing too hard. The key things are making sure your parameters for randomness are set to produce what you want, and ensuring that the seed values for each random component are distinct. Then its making sure the set of breps that are being subtracted intersect with your first set in way which will allow them to be booleaned in a reliable way without failure.
I have a kinda basic understanding of grasshopper, maybe that's why im stuck, I only stared learning rhino like 5 months ago and grasshopper like 2 months ago but they don't teach us how to use specific applications in my course im just trying to teach myself, I didn't even know the proper difference between a nurb and a mesh until recently if that gives you some idea, could you post the grasshopper file if that's possible? I just wanna see what you've done
>students that just do whats required usually get C's
Nobody cares about your degrees in a few years.
If you want to go the extra mile advancing your career, you should get your Cs and use the additional time to do internship or similar for some firms.

Imagine if the additional effort to get to A's will be around 10 hours per week. That's 1-2 hours per day which you could be working for a company or doing your own stuff to improve your portfolio.
Who do you think will be hired in the end?
The one with a bunch of A's or the one with a bunch of C's as well as an ass load of recommendations and work experience?

Definition is attached, but i wouldn't get too into grasshopper until you have some experience using Rhino and a solid understanding of some of the concepts. If you want to learn grasshopper treat it as a side project over the course of a year or two. You also need to think critically about digital tools like this, so you can look past all the hype and understand where using them is appropriate. Otherwise its very easy to get sucked into the glamour surrounding them and wasting lots of time to produce things which are complex but have no substance. As others have said it the thread, you'd be better off doing this concept modelling manually. It will be faster and you'll actually have to think about what you are doing, how these forms might relate to site context, function etc. Doing something like this is pointless if these aspects aren't considered, just meaningless shapes. Get some foam/ soap and carve into it. set a 3 minute timer and spend only that time on each one. Doing this for an hour will be a much better use of your time. Also read this blogpost by the main Grasshopper developer, its relevant.

I agree, i'm trying not to get too lost in it but it's so much fun to learn, also thanks for image, also interesting read, a few things that were mentioned said kinda stuck a chord, like how many architecture students work turns out the same or similar, I notice this all the time at my uni. also I study civil eng so reading that "scientific" paper was pretty funny, I had no idea this was such a big problem in architecture, I just assumed most students were taught how to write papers properly
