JTB TimberTool Trial
JTB TimberTool makes it easy to convert closed polylines into mass elements and makes the bounding box width and depth correct for scheduling purposes in Autodesk® AutoCAD® Architecture and Autodesk® AutoCAD® MEP. The product was initially created for usage with timber but works with lumber, structural steel or concrete shapes. When not registered TimberTool works as a free trial that is fully functional except that you can only convert three polylines per Autodesk® AutoCAD® session. When purchased it can be used without restrictions.
