EastCoast CAD/CAM announced on November 30th that they are now supporting a workflow from AutoCAD MEP and Revit MEP models to their fabrication software.
Here's a snippet of what they wrote:
Sheet metal contractors and engineers can take advantage of this elegant, yet simple, workflow that enables them to take a fully engineered HVAC design from Autodesk Revit MEP and automatically convert the system layouts with real manufacturer geometry and specifications to the industry-standard AutoCAD environment for preparation to drive to fabrication. The workflow eliminates redrawing, and delivers fabrication-ready models inside AutoCAD MEP for final detailed coordination and downloading to highly efficient sheet metal plasma cutting machines. Contractors and engineers have been waiting for and anticipating this release, the impact of which will play a significant role in furthering the adoption of EastCoast CAD/CAM Design to Fabrication solutions.
The rest of their site hasn't been updated to reflect this recent development though so I wasn't able to learn much more about it there. I either completely missed them at AU or they weren't there. So much to do, so little time. Looking forward to hearing about how it works for people!
