I’ve a Microstation DGN file where Building as polygons and each corner of the building polygons have a point, those points have some attributes in the form of MicroStation TAG, i want to check the TAG attribute of the points.

Each point will have many attributes like building no, street name, etc

if any point in the Building with TAG value ES=1 then the trailing point and successor point must be either ES=1 or ES=6

in the below image red point are ES=1 and the orange points are ES=6

i want to check the validate this case

any ideas most welcome

thanks in advance

 

Could a sorter and or using Adjacent Feature Attributes in Attribute Manager provide a solution?
Adjacent Feature Attributes in FME: Reading Text Files - FME by Safe Software
 

hi 

thanks for your suggestion, i tried with this approach but i stuck in between, unable to reach the desired output, can you help me to proceed further on this,

i made workbench as below, where i can’t read the output of attribute manager, because i want to do another check before writing the error flags

the next step would be finding the points which are isolated (not to overlap other building polygons) from other buildings
