Parametric Seating Part 2


This is the contemporary city bench by Rocker Lange Architects.

I had a trouble creating same curves in Grasshopper, and then control them as I wanted.Grasshopper02

It looks that  Brep is not working but it is. I think it cuts the frames and that’s why. But it is working.

This is the sketch of mine, The idea how I wanted create in Grasshopper


Hare are some GIF animations

It’s my firs time doing it, I’m happy haw it looks, I wanted to make it different way but hope next time I’ll make that happen.

Final Seating Assignment

The 3 parameters that I was able to explore with this project was the density of the number of metal mesh pipes that constructed the chair, the radius of the pipes of the chair, and lastly the location of the pipes in the frame of the chair seat…


# of Metal Mesh ranged from 1 to 40

Distance between Pipes ranged from .1 to 1

The radius of the pipes ranged from .1 to 2

Here is the first one… I was pretty happy with how this came out, except I was never able to find out how to trim the object to get the shape I wanted, instead of just the whole area.

Parameter 1

Next I was able to change the radius of the pipes that created the chair…

Parameter 2

Finally, the location of the pipes.. This one came on kind of unintentionally. I didn’t understand this parameter exactly. It involved the “Domain” on the Range button.

Parameter 3

Here is my grasshopper at its best settings:

Jehs-Laub Lounge: Grasshopper Final Version

I’ve been struggling with the screen recordings, so here’s a low-tech version of my parameters in action:


I created the curves for the chair by referencing points from Rhino. I selected the top 3 points and connected a slider to them to change the x and z coordinates.


The bounding boxes that are referencing the geometry (“cushions”) onto the surface can change height by a number slider.


Those same bounding boxes can also be controlled by an attractor point, moving on the surface.


“Cushions” can change size in length….


…and in width. The original chair is a 3×5 grid.

This is the original Jehs-Laub Lounge chair made in Grasshopper:


These are my 5 design proposals, including the Grasshopper parameters I used for each one:

So I’m very excited because I feel like I accomplished two goals: create the form I want, and to create the same form in Grasshopper. I was able to successfully use Network Surface in both Rhino and Grasshopper in order to make my surface. Network Surface

I did as Ben suggested and used a plane over my model that I used as a reference. I was then able to create the network surface without any problems..


I was supper happy with this! Although yes, the metal mesh is still missing and currently the grid is in the wrong direction…….. BUT STILL, PROGRESS.

Grasshopper Attempt 4

I was then able to successfully repeat the network surface command in Grasshopper… However, including not be able to do the pipe command, I also can’t seem to find information on Trimming in Grasshopper………….. HELP.
