This program is a set of AutoLISP routines to annotate ventilation ducts and pipes of Autodesk® AutoCAD® MEP. The annotations are TEXT objects in two lines, a standard in many companies (Width / Height) and which cannot be done by the _LABELCURVEADD command (only 1 line). The annotation isn't connected to the duct.

To learn how to use it, read the General Usage Instructions and watch a video example. A free demo version is available to download at www.autolisps.blogspot.com.
