It can be frustrating for an MEP author when a family is a face-based component that sits on a floor that is inclined at some angle to the pipe network. One tries to draw a pipe down from it vertically, but it refuses to generate.

First check to see if the angle is greater than the pipe connection tolerance. If it is then the connection will not be made.

Instead look at the connector in the family itself. In this case the family is a level-based family that was nested into a face-based family. This is a technique that allows for the “conversion” of a level-based family to a face-based family, but note they will schedule independently, so be careful to exclude one of them from the schedules. The connector that was created in the face-based family is the one that is inspected.

There is a property called “Allow Slope Adjustments” that governs whether the connector will allow the pipe that is generated from it to adapt to the slope tolerance. Make sure to switch this on. When the pipe is now drawn, it can be vertical as per requirement even though the plumbing fitting is at an angle to the vertical. These families are particularly of interest when floor drains, are considered as, especially outside floors are sloped to drain water away. Face based families are flush with the floor surface and appear very neat.
