The more I'm trying to use FOF dimensioning the more I seem to notice that it has limitations.
Namely in my experience you'll see things going awry if you happen to use a dimension from one face of flange to another. The problem isn't with that dimension but if however later in the route you for instance want to remove pipe between the second flange and an elbow chances seem to be bigger that you'll get overdefined or other errors. When taking away the FOF dimension and putting in a 'regular' dimension going from Cpoint to Cpoint (or in other words from the back of one flange to the back of the other) then I can remove pipe without anything turning red or even yellow. Seeing that nothing else changed in the route it stands to reason that the FOF dimension should be the cause of the problem in the first instance.
Does anyone else having similiar experiences ?
