This is how to create a half-tone image using Autodesk Dynamo and Revit for laser-cutting. Dynamo is an open source graphic programming plugin for Revit and Vasari.
You can get a copy of Dynamo at http://dynamobim.org/ ( I suggest downloading the latest daily build) and get a free trial of Revit at http://www.autodesk.com/products/autodesk-revit-fa...
Disclaimer: Dynamo is a new and constantly evolving software development. If for any reason these files or instructions no longer work, or if you have any questions, please direct them to the forums at http://dynamobim.org/forums/forum/dyn/
Begin by starting Revit. Click "New Conceptual Mass" and open the file "mass.rft".
Within Revit, click on the Add-ins tab and click Dynamo 0.7 to open Dynamo.
