Residential stairs very commonly make an L-shaped 90 degree turn and have a riser (2 treads) at that 90 degree turn. That can easily be accomplished in Autodesk® AutoCAD® Architecture with the AEC Stair object, but the method to accomplish this is not readily apparent.
Autodesk has released a utility that will benefit users that need to create a file to be used with the Autodesk’s Navisworks 2010 program. This is excellent news as users no longer must have a licensed copy of Navisworks Manage installed on their computer to create this file. This has real benefits to companies needing to create the exchange file.
