Revit Based HydraCALC (Ribbon/Toolbar/Location)

Button: Hydraulic Calculations Function: Continue Error Type: 1a.1

Description:

Step 1a.1 - Error box - missing Pipe Type pointing to Ref 1 & Ref 2

can also be Step 1a.4

Solutions:

Cause:

1. pipe diameter does not have an internal diameter for that size pipe being used or bad fitting sizes

1A. same as above but in metric pipe sizes are not nominal.
Solution:

1. Revit -> Manage Tab -> Inquiry ->Select By I.D., enter a reference I.D. and Revit will zoom to the fitting. Fix fitting or place a system divider on the pipe.

If you'd like a further explanation: Here is a 10 minute video detailing the process on how to resolve this error

1A. Metric sizes are literal in the model, not nominal - for example 1" in imperial is equal to a nominal metric dimension of 25 mm, but literally converted the size is 25.4 mm.  All metric diameters must be the nominal size (25, 32, 40, 50, etc.) and not the literal size.  Best bet to fix, bring in Pipe Types from the toolbox and convert existing literal diameter pipes to the nominal diameters by switching to HCAD pipe types. Note: one must pay close attention to conversions because the literal diameters round up i.e. 25.4 becomes 32.
