If you haven’t already heard of Tekla BIMsight, you should take a look. I first saw it at one of the AGC BIMForum conferences last year. It is a free – yes, free – tool for 3D coordination using aggregated design or fabrication models (notice, no kittens harmed here). BIMsight now offers support for tablets including multi-touch hand gestures as well as stylus use. And yet again, another tool that uses – guess what? – IFC format for input.
I’ll be running some informal tests of this tool in the near future. In the meantime, feel free to share your experiences in the comments below.
