I’m not a fan of linking Autocad into Revit, but sometimes you just have to. We recently were having problems with AutoCAD Mtext not importing correctly. In the AutoCAD dwg file the Mtext was set to wrap, but when linked into Revit it wasn’t wrapped.
The fix we got was strange but it works. In the AutoCAD drawing by putting a space (space bar) at the very end of the text, when linked into Revit the text will wrap. It’s totally buzzer but it works.
