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 which is a standard in many companies (Width / Height) and which cannot be done by _LABELCURVEADD command (only 1 line). The annotation isn't connected to the duct.

To learn how to use read the General Usage Instructions and see a video-example. Free demo version available to download at www.autolisps.blogspot.com.
