I made a quick YouTube screen capture of some dynamic timber components I’ve been working on. SketchUp Pro V7 adds new functionality to create parametric components – in this case timbers and joinery that can change size from an option menu as opposed to editing the geometry. Displayed in the video are: dynamic gable shell creator, dynamic posts and timbers, a dynamic rafter, and examples of dynamic joinery. I’ve detailed two small frames using a combination of the dynamic components and Clark Bremer’s TF Rubies. The components need a bit of work – but in all they are a great first step to creating a parametric based timber modeling package.
Dynamic Timber Components
March 9th, 2009New Hardware
March 2nd, 2009I’ve been migrating my software from the old machine to the new… a dreadful task. Two days of head scratching with a timber app and we’ve finally sourced the problem – and hours of waiting for my backup drive to copy then to paste. The new machine is blazing fast compared to the old. SketchUp was starting to bog down with complex models, and the recent version of AutoCAD was nearly unusable.

Structure Under Tension (we’re all connected)
February 25th, 2009I created this piece while teaching design at the Cleveland Institute of Art. I’ve unearthed it from my archives as I’ve had a chance encounter on a project that reminded me how small the world is – and how interconnected we all are.
The piece attempts to reflect the interconnected nature of the world, where actions we take are linked through a web of ecosystems, potentially affecting the stability of the structure – the stability of the whole as influenced by small actions. A current that ran through my class was the blending of traditional craft with conceptual art – and my students’ work focused on blending the disciplines of ‘thinking’ with that of ‘making’. This object was the result of turning the tables on my students and asking them to write the final assignment of the semester. Both instructor and students would create works that enmeshed recent changes in our world view within an object.
Structure Under Tension is a kinetic sculpture made of wood and steel cable. 26 wedges and 26 keystones form a circle. Steel cable links keystones opposite each other across the circle and individual cables extend outward from the wedges to wooden handles. Participants assemble the structure on the ground, sit in a circle, and pull on the handles. The circle locks together, becoming a tension ring with each piece of the circle compressing on it’s neighbor. If the tension is equal and controlled around the circle, the ring lifts off the ground and floats. When pressure becomes unequal, the integrity of the structure is compromised and the ring collapses. The forces involved in holding the circle together are easily visualized – but the variables in the pressure are not easy to control. Predicting where the ring will break is impossible – as the slightest change in pressure finds the weakest link and starts to break the chain.

February 23rd, 2009I will be teaching SketchUp for Timber Framers at the Heartwood School May 25-27, 2009. Check out the course description – and sign up soon – our last class at Heartwood booked solid!

SketchUp – New Hampshire
February 11th, 2009
The view from our wonderful accomodations.
Returned from teaching an intense two day introduction to SketchUp workshop in Tamworth, New Hampshire. We had a small class and focused on using the software for timber frame design (but the techniques can be applied to furniture design, woodworking, and other general construction tasks). The group had a wide range of skills – so we started with the absolute basics and worked our way into compound roof design, shop drawings, and even took a quick look at exporting materials lists for estimating and job site coordination. In the right hands and with a bit of creativity SketchUp can be a powerful presentation, fabrication, and estimating tool for designers and builders. Special thanks to Jon and family for putting us up in a wonderful rustic farmhouse with an amazing view of the White Mountains.
