Parametric Bench (Grasshopper Tutorial)

In this Grasshopper tutorial, I will model a parametric bench by using three different sections and a curve as the bench's rail. First I will orient the sections on the rail and then I will sweep to produce the results. In the end, we will make the sections with "per frames".

Hey coders! If you're having trouble with your cross-sections being rotated, attach the "Perpendicular Frames" mod to "Flip" mod and then to "Target"

Very best made multi object with Grasshopper,
really interesting

thanks for good tutorial!! i did it 4 times!! it was so difficult for me but good tutoriall! thank you!

For people who are searching to flip the bench. The only way it worked for me was to add a 'flip plane' after the 'perp frame'. Then connect toggle switches ('boolean toggle') to the 'flip plane'. Double click the toggle to flip in the desired axis.

I just want to let you know that I learned a ton from thank you for

[fatemehnorouzzadeh]

I would appreciate your considering this. I need to know more about this software to start, actually, I find myself really interested in

[juliocesarcorralesardiles]

Thank you!! I had some of the problems mentioned down below but I kinda figured my way out of them. Loved this tutorial

wow you always make it look like it's easy to do.. 😂

[한수몬]

thank you so much for tutorial !! but I can't connect multiple "number sliders" on "perp frame". I can only connect one. how can I solve it?

[tatsianakublashvili]

Очень простой и быстрый алгоритм! Спасибо! 🌼

flipped curve to the "Perp Frame", "Perp Frames" and "Sweep 1" its not fliping in opposite direction but flipping in 90 deg.

hi, than you for this informative video, I have got a PROBLEM: I did every single thing u made in Grasshopper, but I still get "data conversion failed from curve to surface rhino", would you please help me out?

[baothunguyendang]

Thank you very much for such a helpful video. Just a little question: When I connect the 3 number slider to the perp frame's parameter, it only takes 1 and on the curve there's only 1 section even though I already selected 3 sections and 3 curves in order. What do you think the problem is? Thank you

[percynovak]

For those that had the same problem I had were the the 3 curves were flipped and the comment didnt work for you guys what I did was to rotate the curve in the rhino instead of modifying the grasshopper parametrics. Hope this help you guys.

[hengamehdaghighi]

Thank you for your tutorial, it's amazing.
i have a question, so i did everything you explained but there is a problem that my curves intersection are rotated in minus z direction, i mean instead of being in a right direction they are in the opposit. it seems the bench is rotated. i dont know ehat i did wrong. can you help me out please?

[raywong]

I think I finally know why it is always upside down. you guys can try to flip you rail curve, mine is working now.

[aaa-qzmn]

Hi from Argentina! Do you Know how make the surfaces parallels to curve instead of perpendicular? Thanks!

[genalejandromoyajimenez]

Why i cańt connect more than one slider to the Perp Frame? Thanks it looks awesome!!!

[mariuszmilewski]

very cool, I am curious if it is possible to divide the object so that the distances between the elements are different as well as the thicknesses of these elements

(can it be done easily in a softwere)
