Sketching under Building Regulations
At the initial design phase of an apartment project in İstanbul, Nilüfer Kozikoğlu (TUŞPA Architecture) has offered me a job I haven’t done in Grasshopper before. This definition includes a sketch of a possible apartment renewal, analyzing and optimizing data from the contractor’s and property owners’ perspective. It also checks if the proposed solution is appropriate according to the building regulations for that area. In Turkish, KAKS means the maximum total floor area / land area, and TAKS means building base area / land area. All data input are parametric, so this solver can be implemented in most of the situations (except that the shape of the land area is not rectangular). Also Nilüfer asked for an addition that declares the different floor types, lofts with two storeys and green gardens that also have to be calculated.

Quantity Surveyor
February 26, 2024
This work emerged out of necessity. In the design and application process of wooden frame structures, where we put thousands of pieces together like a puzzle, the issue of preparing and updating quantity and measurement lists requires the most effort. Hours spent on this and the possibility of making mistakes are very high. However, with the Quantity Surveyor I developed in Grasshopper, you can generate measurement lists almost in real-time. All that needs to be done is to model each…
Fermat’s Nightmare
October 14, 2026
Revisiting a specific mathematical phenomenon that I previously explored twice, here (in 2017) and here (in 2011), from a different angle in 2026 now. This was the final video (from 2023) that I found in my junk folder during the blog’s resurrection. Today, designers mostly know Fermat through the famous 137.5-degree angle of rotation, which is the mathematical formula used to describe the arrangement of sunflower seeds. However, today I will speculate on a nightmare of Fermat’s. Because Fermat, in…
Campanus Sphere
October 9, 2026
I want to introduce a concept I came across the other day, one I had never heard of before, along with a few fantastic websites. The Campanus Sphere is essentially a rather crude spherical representation, the kind I’m used to seeing in (very old) computer games, and it also makes a nice nod to 80s disco culture. I also recall that in many older CAD software packages, spheres and sphere-related Mesh objects were represented as polyhedra using this method. However,…
Field Deformation
October 8, 2026
Ever since I restructured designcoding, I’m still sorting through the trash folder. All 580 posts published on the blog have been reviewed, and their files have been uploaded as open source. The mysterious trash folder, where I couldn’t even tell where things belonged, is shrinking fast. While checking this folder yesterday, I found a video. This is probably a simple tutorial I prepared about 10 years ago for the parametric modeling elective course (probably related to this 2012 post). The…
Damped Harmonic Motion
October 7, 2026
Have you ever thought about making a damped pendulum in Grasshopper? I have no idea why, but I did. I just decided to transfer a Python snippet I found online into a Grasshopper definition. Here, the Initial Angle (Radians) Number slider sets the initial angle to any value from 0 to Pi. The letter G represents the acceleration due to gravity (approximately 9.81 m/s2). This is the primary force pulling the pendulum downward. As you know, pendulums wouldn’t swing without…
