Twisted Surface

Currently working on a project for a small restaurant in Ann Arbor. Here are a few studies that continue the explorations into developable surfaces and smart surfaces. At this point it is not clear if we will have the time to explore a dynamic / responsive system or simply develop a restrained surface to create subtle distortions in the ceiling to allow for HVAC and lighting requirements.

Here is a parametric model that looks at using two servo motors to create s simple wave movement.













Simple walkthrough of a static surface illustrating the open and closed conditions of the surface made of sheet metal strips.

Assemblies and Aggregations

A recent exhibit in the college gallery showcased student work from my ParaMod seminar and from Glenn Wilcox’s Digital Fabrication Seminar.







This post seemed like a good opportunity to post some of the work from last semester. Click on the project images to open the final PDF board which shows various configurations and mutations.

Digital Project to STAAD

Here is a quick series of steps to go from Digital Project to STAAD. A few basics moves in STAAD will have quick feedback based on changes in geometry.

Click here for the video tutorial.

Simple animations below of three variations based on self weight loading. The cross member is in three positions 90%, 50% and 10% of its location to the vertical member. I was pleasantly surprised to realize that the 10% geometry deflects the least given the simple loading.

Grad Studio to engage Parametric, Biomorphic, and Structures

Cultivated Form

Through a whole series of unrelated events, my graduate studio this term will expand on parametric design, biological research and the design of wood structures. A new initiative is looking at linking technical courses with design studios. This is a first for Michigan and we are the test subjects. In our case students registered for the studio are also registered for the graduate wood structures seminar taught by Peter von Buelow. This limits both classes to the same group of students allowing us to modify to make connections between the two.

Given my ongoing interest in biological systems, genetics, and morphology the studio will look to the botanical. To this end we are making connections with evolutionary biologists and botanists from U of M. They have already been very helpful in discussing the "rules" that might be at play behind various genetic mutations and adaptations. In many cases producing a wide array of variation with simple rules.

As a means to push the discussion further and our need to get to a point of proposing wood structures, we are working with the New York Botanical Garden to develop a series of hypothetical / theoretical / prototypical projects in response to their future building and exhibition needs. Given the freedom and content of the studio, I imagine student will will find its way onto the blog.

Knowledgeware Optimization

This tutorial introduces the knowledgeware warning function and multi-parameter optimization. In this tutorial I model a simple room and use its dimensions and configuration to analyze surface area and volume. Using the values, the reverberation time is calculated. As a first attempt at using the engineering optimization tools I let the software determine the room dimensions based on appropriate reverberation times.

Random Numbers for Framework

This video tutorial attempts to pull together a few of the previous examples. A powercopy is used to adapt to its height and to be divided based on a random number from an Excel design table. The Excel spreadsheet can be a powerful tool to control geometry.

Framework Options

Short video tutorial describes three methods for the creation of frameworks for use with doc templates and powercopies . Click the image to start the video.

Fire Installed

John and I finished the installation of the Fire project and the the opening occured last night. Once I get a chance to photograph it I will upload more. For now, here are some i-phone shots.

There is more up on John's blog: http://designedobjects.blogspot.com/.

And some images from the opening from Earl Carlson: http://www.theearlcarlson.com/duderstadt/fire.html

'Fire' from John Marshall on Vimeo.

Unfolded PowerCopy

Tutorial that explains how to include unfolded geometry in a powercopy.

The tutorial also shows how to use local and global parameters.

18 minutes. Click the image for the video.

Arts & the Environment: FIRE

As part of a University of Michigan initiative to explore arts driven inquiry, Arts on Earth sponsored multidisciplinary faculty teams to develop work that explores environmental issues. Since the summer I have been working with John Marshall from the School of Art & Design and Werner Dahm from the Laboratory for Turbulence & Combustion (Department of Aerospace Engineering). We were given the element of fire.

The opening night of the installations / performances is on: November 5 from 5 - 11.
Here is a link to Arts & the Environment.

A series of aluminum forms will hold an array of autonomous interactive units that will respond to the movement and environmental conditions around it. The behavior is obviously informed by the dynamic qualities of fire.

Random Numbers linked from Excel

This tutorial will describe the creation of a design table, allowing for the control of geometry from an Excel spread sheet. The design table is also useful for input and output of data from Digital Project. Using the random number generator from Excel, a rule is created to randomly open or close the geometry of a powercopy.

Grasshopper - Brick Surface

This grasshopper example places a series of boxes on a lofted surface. Currently it is an approximation of a brick surface. The next file will follow the rules for corbeling to set a maximum curvature based on a brick module.

Here is the grasshopper file.

Grasshopper - Array of Boxes

Simple Grasshopper video tutorial that shows how to make a series of boxes re-orient themselves based on a point.
Beyond the simple re-orientation the file uses both a MAX and MIN to control the size of the boxes.

Digital Project - Tutorial 5 - Document Templates

This is the fifth and last comprehensive tutorial for the ParaMod seminar. The five tutorials should give everyone a basic understanding of many of functions. I will continue to add shorter more specific tutorials.


Document templates allow for advanced replicatiopn at the product level, each part of the syetem is a separate file.

Digital Project - Tutorial 4 - Power Copies

Here is the fourth Digital Project tutorial developed for the ParaMod Seminar.

It is 45 minutes long and introduces advanced replication using a simple framework.

Digital Project - Tutorial 3 - Part to Whole

Here is the third Digital Project tutorial developed for the ParaMod Seminar.

It is 48 minutes long and introduces solids and part / product relationships.

Digital Project - Tutorial 2 - Surfaces

Here is the second Digital Project tutorial developed for the ParaMod Seminar.


It is 65 minutes long and builds on tutorial 1. Here we will use the first sketch to drive the height and shape of the covering surface. At this point the form is less of a concern than learning how to develop the interactions.

Digital Project - Tutorial 1 - The Sketch

Here is the first Digital Project tutorial developed for the ParaMod Seminar. It is 42 minutes long and covers the interface and the sketch. Let me know if I left anything out.

ParaMod Seminar: Structural Density

It is that time of the year; back to school. This semester I will be running the ParaMod grad seminar at the Univ or Michigan School of Architecture. Rather than work with a different topic I am continuing the work that we started in the spring term. The seminar will again be looking at the relationship between structure and organization. Obviously the associativity and intelligence of the Digital Project modeling environment allows for various ways to explore the topic.

The plan is to post samples of the student work to share the research. A series of video tutorials will be developed to support the seminar work. I will be posting these tutorials here too.

Here is a link to the syllabus for the seminar.
