To rotate my maps in  a mapbookserie using ARcMap, i extract a angle using

 

oriented boundingboxes.

 

I use the option to use a attribute for the sides. It's an option in the transformer Boundingboxreplacer.

 

After chopping the boundingbox i use an expressionevaluator to test for

 

lenght of longest side = @Value(length). to acqurie angles of the longest sides.

 

 

Tester then said all failed???

 

 

So look at what fme does:

 

 

 

Up to four of the last digits appear different. Not one is the same. (only talking about those that should be the same angel of course.)

 

I assume that lenght() function is accurate. But what is up with the lengthcalculation of the BB-replacer.

 

And does this also occur in 2014 version?

 

 

This is in oriented mode BB_replacer mode, have not checked non-oriented.

 

 

( i now round the test to like 6 digits, its just for selection anyways)
