If Revit wants to be taken seriously as a rebar detailing solution then the UK Rebar shape codes need to checked and corrected so that they function in accordance with the British Standard.
So far I have found that 23, 25, 26, 27, 28, 32, 34, 35 and 46 are all wrong. The UK does not have standard hooks, we need to be able to specify the leg length(s).
Also a number of shape codes report values for dimensions that should not be in the schedule but appear to be required to manipulate the bar.
It would appear that the old content generator was able to create correct UK shape codes, so why aren't the ones included in 2017 and 2018 correct?
