Hi
I am still new to FME and would like to find out the best/easiest/quickest way to calculate lengths of pipe sections. In this case the distance between S01 and F01 (3.8-0.6 = 3.2). The tricky bit is that there are sometimes more than 1 pipe section per Inspec_ID which need calculating, ie S02/F02, S03/F03 etc.
Thanks in advance

So I'm not sure if I understood exactly what you need, but here's a sample workspace that calculates distances between S01-F01, S02-F02, etc. Unfortunately it isn't trivial (if I've understood the requirements correctly), so I ended up with some Python to do the actual list calculations.
The section lengths are output in the list attributes lengths{}.distance and lengths{}.name
Output from the sample dataset:
`lengths{0}.distance' has value `3.1999999999999997'`lengths{0}.name' has value `S01-F01'`lengths{1}.distance' has value `85.3'`lengths{1}.name' has value `S02-F02'`lengths{2}.distance' has value `4.299999999999997'`lengths{2}.name' has value `S03-F03'`lengths{3}.distance' has value `5.200000000000003'`lengths{3}.name' has value `S04-F04'If you need one feature per section, use a ListExploder on lengths{}. You can then also use the AttributeRounder on the distance values, if needed.
Hi @johannhurter
thank you for the data sample. I think the workflow might be

Hi @johannhurter, using global variables for each interval might also be a solution, if it's guaranteed that "Fxx" appears always later than the "Sxx" containing the same xx (01, 02, ...).
The next step is to look for areas where 2 pipe sections overlap, e.g. S01/F01 and S02/F02 running on the same section of pipe, and only counting the longest section. If anybody has a quick answer in the meantime feel free to shout ;)

then again...2 transformers seem enough..
