Revit MEP 2013 section geometry is not working properly. Some pipe and Duct etc. are popping up outside the cutting frame. Is there a hot fix for this or just need to work it out on the setting? RMEP 2012 was not like this.
Got the same issue, It is a bug with the software. When a pipe has
insulation on, it looks at the bounding box of the insulation so if the
insulation is on an angle that bounding box becomes quite large. The workaround
is to turn off pipe insulation in sections... Autodesk are aware of the issue,
as I have logged to them on another occasion.
